The Brain and Behavior Essay

The temporal and frontal lobes of the brain play a significant role in behavior and decision processing. The temporal lobe is located in the bottom middle part of the cortex, or more commonly recognized, right behind the temples on each side of the brain. It is primarily responsible for processing auditory information for hearing and comprehension. (Brainmadesimple.com, 2014) The frontal lobe is located in the upper are of the cortex. The primary function of the frontal lobe is processing higher mental functioning such as thinking and decision making. (Brainmadesimple.com, 2014) It is also one of the four major divisions of the cerebral cortex.

The temporal lobe regulates memory, hearing, emotions, language, and learning abilities. Sensory receptors work together to regulate overstimulation of the various criterions. The temporal lobe also works to turn short term memory into long term memory. When damage happens to the temporal lobe Wernickes aphasia may occur. Wernickes aphasia affects the left temporal lobe; however five percent of individual the right temporal lobe is affected. This damaged condition results in receptor problems. The individual may have the ability to hear speech, but they will have a great difficulty understanding the meaning of the words. Other disorders that affect the temporal lobe are epilepsy as well as dementia. Other damage symptoms of the temporal lobe are problems with visual perceptions, impaired long-term memory, and changes in affective behavior and personality. Sexual behavior may also change dramatically.

The frontal lobe regulates movement, decision making, problem solving, planning, and voluntary muscle movement. The frontal lobe is located in the frontal prefrontal cortex of the brain. If the frontal lobes are damaged it could seriously affect the individuals personality and emotional stability. It would dramatically change the course of the individual’s life. Frontal lobe damage will reduce an individual’s self awareness, reasoning or planning skills, and the ability to move smoothly through various life situations. This type of brain damage statistically increases the chances for drug addiction and impulsive decisions. Addictions can only cause more harmful damage that could only worsen the effects of Brocas aphasia. Brocas aphasia is a disorder that causes an individual to struggle with fluently utilized words. It particularly affects grammar and pronunciation. The frontal lobe is also the primary area of which ADHD affects the brain. It is directly the abilities to concentrate and make decisions that are affected. The damage of dementia also begins in the frontal lobe causing memory, self awareness, and concentration damage.

The Brain and Behavior Essay

...The Brain and Behavior Essay The Brain and Behavior Essay The temporal and frontal lobes are only two of the four lobes that make up the neocortex. Both have very specific responsibilities within the brain. The frontal lobe of the brain deals with executing behavior. This behavior ranges from individual muscle control, to complex abstract planning about what to do ("Examining The Brain’s Four Lobes: Frontal, Parietal, Temporal, And Occipital", 2015). Within the frontal lobe are four different cortex. They are the prefrontal, orbitofrontal, primary motor, and the premotor cortex. The prefrontal cortex makes up the majority of the frontal lobe. This cortex is responsible for all skills that require intelligence. The prefrontal cortex is larger in primates that any other mammal. But humans have larger prefrontal cortex than primates, and primates have a larger prefrontal than any other mammal ("Prefrontal Cortex", 2015). The prefrontal cortex is located in the front part of the frontal lobe. This area of the brain is where complex cognitive behavior, personality expression, decision making and moderating social behavior is processed. Thoughts and actions are considered to be the basic activity of this region of the brain. The anterior and medial part of the brain is made up of the orbitofrontal cortex. This is where assessments of risk and reward, as well as moral judgment are weighed. It is located in the frontal lobes and...

Brain and Behavior Essay

...White February 2, 2015 The Brain and Behavior Essay The human brain is a very multifaceted and sophisticated organ. Understanding the function of the brain is often very limited to the understanding of the brains areas or regions with regard to how these areas respond to stimuli or how it responds to damage. Much of the understanding of the brain is embedded in observation of damaged brains and their association of impaired function with specific areas of damage. Modern technologies have begun to change this trend because of machines such as the Magnetic Resonance Imager (MRI) that allows scientist to observe brain function with the invasiveness of surgery. This technology has provided not just insights into neuroscience but also into psychology as brain functions can now be correlated better with behavior and heredity. One can see this insight when examining specific areas of the brain such as the temporal and frontal lobes of the brain. The MRI lets the scientist get an in depth look at the brain in slices of an image to better interpret how the brain works. The cerebral cortex is “a large, extremely wrinkled sheet of neurons, or nerve cells, on the surface of the brain’s two hemispheres”. These are defined as the right and left hemispheres and make up the largest volume in the brain. The cerebral cortex controls all sensation, thought, comprehension, higher cognition, ideas, language,......

Brain and Behavior Essay

...When most people think about the brain they think of how it can process memories and helps the body function, but what most people fail to realize is that the brain has different parts for different functions. These different parts of the brains are broken down into categories called lobes. The lobe that controls a person’s hearing and language is the temporal lobe. The temporal lobes are actually located on both sides of the brain. The temporal lobe helps people register what it is they are hearing when they are either talking or listening. When some sort of damage is happened to the temporal lobe people are able to still hear things but will have a hard time understanding the meaning of words, this is called receptive (or fluent) aphasia. This damaged area is also known as the Wernicke’s area. The most important part of the brain that really makes up a person’s self and has higher mental abilities (which means it helps with reasoning and planning) is the frontal lobe part of the brain. The frontal lobe gets its’ name from the location of the brain. It is in located on the front part of the brain and it is a massive lobe at that. Not only does the frontal lobe make up a person’s self, but it also has another role which is motor control. Motor control refers to every movement that your body can make. These movements can be as little as moving a finger to as big as running or swimming. Another thing to know is that the frontal lobe has more tissue dedicated for certain......

This lobe has different functions, mainly auditory detection, keeping memory and emotional perception. The hippocampus happens to be an area of the brain that consolidates information from brain. The damage to this lobe is mainly linked to the impairment of an individual experiences. For instance, damage that occurs to the left lobe may cause difficult noting words while damage to the right lobe can cause lack of talk inhibition. One of the well noted behavior due to damage to this lobe is attention type of disorder, victims proving distraction and inability to attention. They give incompatible memory, sometimes it is called forgetting to recall. The way of thinking of victims with this injury happens to be hard, and they may prove some improper issues in their way of responding. This preservation, with inability to change form one way of thinking to another, brings difficulties with calculations, such as carryover subtraction. Aphasia is not all times observed, but this so contrary from Wernicke’s and Broca’s response on it. Victims have well monitored motor speech. Repetition is always......

Using Examples of Case Studies, Critically Evaluate the Contribution Cognitive Neuropsychology Has Made to the Understanding of Normal Cognitive Function.

...investigates the function and structure of the brain as it relates to processes of cognition such as; memory, perception, thinking, recognition and the human ability to solve problems, ( Jansari, 2010 p.60). Since the second half of the nineteenth century neurologist began studying brain damage in patients, more specifically their research has examined the effect of brain damage and its implication for normal cognitive functions. It has therefore being argued that in order to understand a working system, one must understand how it can fail, (Jansari, 2010 p. 59). This can refine and possibly constrain existing theories, as well as inspire the formulation of future concepts with regards to the structure of normal cognition. Evidence is based on case studies of individual brain damaged patients who show deficits in particular areas of the brain, from such studies researchers infer that different areas of the brain are highly specialized. Furthermore the development of more accurate techniques, aided by more effective research paradigms has increased our understanding of cognitive functions, in areas such as disassociation, plasticity, memory, localization and face processing, which would be explored later in the essay. Cognitive neuropsychology has however shown that there are limitations in understanding cognition where questions regarding methodology may arise, for instance studying single patient symptoms may pose problem for generalization.

The Brain and Behavior

...The Brain and Behavior Essay BEH/225 3/15/2014 Jennifer Reed Did you know that there are four lobes that are within the brain that control the way our behavior is. The frontal lobe and the temporal lobe are the two that we are going to discuss and how they control our behavior. We will also look at what heredity has to do with our behavior and if the lobes were damaged what could the affects be. Broca’s and Wernicke’s had aphesis on the lobes. The frontal lobe is associated with being able to have higher mental abilities and play a role in your sense of self. The frontal lobe is also responsible for the control of movement. The movement comes from the tissue of the rear of the frontal lobe it is called the primary motor area it directs the body’s muscles. The primary motor is one of three actions that the frontal lobe controls. The second one is the mirrors neurons these neurons become active when we perform action. The association area combines and processes information. If there were damage to the left hemisphere may suffer aphasia. The temporal lobes are located on each side of the brain. These lobes are the direct reason why people can hear. Auditory information projects directly to the primary auditory are making it the main site where hearing first registers. The temporal lobe is also responsible for the language that is spoken. If it is damaged the result is a receptive or fluent aphasia. Let’s talk about what is aphasia and why there are two different...

Origins of Psychology

...and ideals that each individual holds dear and sacred. In short, real philosophy cannot start until one’s mind begins to examine itself. Again the mind is central and paramount. To modern psychology he gave the Socratic Method of questioning, which demanded definitions be as accurate as possible, clear thinking at all times, and exact analysis of all details. Hippocrates (460-370 B.C), the father of medicine, developed a new method of research that necessitated the need for careful observation followed by precise collection and interpretation of facts. This method was incorporated into the study of individual physical, emotional, and mental reactions. In essence, he gave psychology the systematic observation of human behavior. Western Philosophical Influence Philosophy is a multi-faceted word. Some individuals choose to associate the term “philosophy” with the hunt or quest for knowledge and wisdom. Others relate to an in-depth study of moral obligations and social responsibilities of humans. Others seek to answer to question of life itself, the purpose, intent of, and how human life fits into the universal picture. Many are the names associated with such thinking, too many to list, yet one not more important or less of value than another.

Brain Structures and Functions

...Brain Structures & Their Functions The brain forms part of the central nervous system together with the spinal cord. The nervous system is the center of all communication and decision making. There are two parts of the nervous system: the central, and the peripheral nervous system. The nervous system as a whole is in charge of every part of our daily lives. Breathing, blinking, reaching to grab your phone, these are all motions brought on by our nervous system. Sensory nerves are the group of nerves responsible for gathering information from the body, and passing it along to the spinal cord which sends that message to the brain. The brain will then combine the message, and produce a response. The spinal cord acts as a superhighway of messages. It’s made up of a collection of nerves that go up and down the spine sending messages back and forth to the brain. The brain is composed of three sections: the hindbrain, the midbrain, and the forebrain. The hindbrain includes the cerebellum, the ponds, and the medulla. The midbrain includes the tegmentum and the tectum. Lastly, the forebrain includes the cerebrum, the thalamus, and the hypothalamus. The hindbrain is an area of the brain that coordinates information coming in and out of the spinal cord. It controls the most basic functions of life such as respiration, and our motor skills. There are three structures that make up the hindbrain: the medulla, the cerebellum, and the pons. The medulla is located just above the......

The Neuroanatomical, Neurophysiological and Neuropsychological Aspects of Obsessive Compulsive Disorder.

...Obsessive-compulsive disorder (OCD) is a psychiatric condition affecting about 2% of the population. Subjects with OCD typically suffer from recurring intrusive, unsettling thoughts and repetitive, ritualistic behaviors. This essay discusses the neuroanatomical, neurophysiological and neural psychological aspects of obsessive compulsive disorder. A range of studies have identified several regions within the brain thought to contribute to the disorder including the orbitofrontal cortex, important in reward based learning, the anterior cingulate cortex, important in error detection, the basal nuclei, involved in motor control, and the thalamus, involved in processing and relaying sensory information. These regions form part of larger neural circuits which could be responsible for the disorder. OCD causes a number of cognitive deficits in its sufferers, from problems in self-perception and regulation to memory and planning deficits. The Neuroanatomical, Neurophysiological and Neuropsychological aspects of Obsessive Compulsive Disorder. Obsessive-Compulsive Disorder (OCD) is a psychiatric disorder thought to affect between 2% to 3% of the population (Koprivovaa et al., 2011) marked, as its name suggests, by recurrent intrusive thoughts which produce anxiety usually with repetitive ritualistic behaviors intended to reduce or neutralize this anxiety. Compulsive actions can include checking, counting or repetition, ordering and symmetry, washing, and hoarding (Neel, Stevens......

Brain and Lobes

...The Brain and Behavior In this paper I will be discussing the contrasting roles of the temporal and frontal lobes on behavior. What types of behaviors the temporal and frontal lobes are responsible for, and finally what can possibly happen if there is any damage within these lobes. According to the Merriam Webster online dictionary, the brain is an “organ of the body in the head that controls functions, movements, sensations, and thoughts.” (Merriam Webster, n.d.) The cerebrum is the largest part of the brain; and is divided into two hemispheres and four different lobes. Each lobe controls many major functions, behaviors, emotions, and feelings that we need and use in our everyday lives. Lobes and What They Control There are four different sections in the brain called lobes, these lobes are called, the frontal lobe, the parietal lobe, the occipital lobe and finally, the temporal lobe. Each of these lobes has different functions that contribute to the many different behaviors of people. The frontal lobe, also called the cerebral cortex is located at the front of the brain right behind the forehead. This lobe is associated with reasoning, higher level cognitive, motor skills, and expressive language. According to K. L. Hartwig, the frontal lobes of the brain “are the seat of emotions and judgments related to sympathy, which is the ability to feel sorrow for someone else's suffering, and empathy, which the ability to understand another's feelings and......

The Major Effects of Alzheimer's Disease

...The major effects of Alzheimer’s disease The former liberal party leader, Michael Ignatieff said in his essay, “Deficits” (2010) “Sometimes I try to count the number of times she asks me these questions but I lose track” (p.108). Ignatieff is expressing his own feelings towards his mother’s Dementia of Alzheimer’s disease. Dr. Alois Alzheimer, a German physician discovered a patient that suffered from a severe dementia due to brain abnormalities. Alzheimer’s disease is the second most-feared irreversible illness in America, following Cancer. It affects as many as 5 million Americans, a number that could soar to 16 million by 2050 (Hoffman, Froemke, and Golant, 2009, para 1). These numbers are due to the fact that there is no cure. The major effects of this specific disease can be depicted by Ignatieff (2010) in “Deficits” and also scientific studies that create a clear picture of how an individual is affected through the brain, how the individual does not have that sense of security and those caregivers who are trying to cope with the disease to that individual. The brain is a vital organ in the human body, when the brain is affected; the entire functions of the body are affected. In most individuals affected by Alzheimer’s, memory loss is usually the first sign. The individual begins to lose memory of recent events and later the ability to complete regular tasks declines as nerve cells break down. In the book, “The Everything Health Guide to......

In other words, how does the physical brain affect our psychological behavior? It is a biological approach to the study of psychology. This has also been referred to as psychobiology, behavioral biology, or behavioral neuroscience Biopsychology did not develop into a discipline o f its own until the 20th century. While the exact date s not clear, in 1949 the publication of “The Organization of Behavior” by D.O. Hebb. This publication was significant in its emergence in bringing biopsychology to the forefront of study. In this book Hebb's theory was about the complex psychology such as perceptions, emotions, thoughts, and memories might have a strong influence from actual brain activity. Hebb based his theories on experiments of humans and laboratory animals, clinical case studies, logical arguments, and his own observations of daily life. To go back even further, we can look at Aristotle, or Plato. While it may not have been considered as a study of it’s own, we should not forget their early contributions. It is the very beginning of taking a look at the brain as the key to all thoughts, behaviors, and philosophical thoughts. Aristotle looked at the brain in ways that were not yet considered.

The Brain

...The Brain and Behavior Essay The brain is an organ that serves as the center of the nervous system in all vertebrate. The function of the brain is to exert centralized control over the other organs in the body. Contrasting the roles of behavior of the temporal and frontal lobe seems to be quite interesting. Temporal lobe is one of four major lobes of the cerebral cortex. This particular lobe is responsible for the retention of the visual memories, processing sensory, comprehending language, storing and emotions. The frontal lobe is located in the front of the brain. It contains most of the dopamine sensitive neurons in the cerebral cortex. It has similarities of the temporal lobe. Some of the behaviors that the frontal lobe is responsible for are conscious thought, voluntary movement and a person individual personality characteristics. Any damages to either frontal can cause a change in a person’s emotions, they become less motivated to do anything and they become very aggressive in their behavior. Paul Broca did a study that involved language in 1861.His first studied was a deceased patient that had a problem that caused him not to speak nor express his thoughts in writing. He came to find out the he had a small size lesion on the left inferior frontal cortex. After several other studies he discovered that they all had a small lesion and this is when he made the statement “We speak with the left hemisphere” and identify the existence of a “language centre” in the posterior......
