...Brain Response of Behavior BEH/225 December 15, 2013 This paper will explain the communication process of the neurons in the brain, the major regions of the brain and what functions of behavior the systems of each region control, and the sensory process. Part I There are 100 billion neurons in your brain. They are the basic building block of the nervous system. They are also known as nerve cells. There are three parts to a neuron, the dendrites, the cell body and the axon. Using electrical and chemical signals neurons convey information; this process is the foundation for brain function. Neurons need to transmit information within the neuron and from one neuron to the next. To do this they use electrical signals and chemical messengers. Dendrites receive information from sensory receptors or other neurons. The information is then passed down to the cell body and on to the axon. It then travels down the length of the axon as an electrical signal. This is known as an action potential. Action potential is also known as the nerve impulse. It sweeps down the axon reaching speeds up to 200 miles per hour. There is a microscopic space between two neurons that messages must pass. This space is called a synapse. When an action potential reaches the tips of the axon terminals, neurotransmitters are released into the synaptic gap (Coon & Mitterer, n.d.). Sometimes electrical signal can bridge the gap. If not the neurotransmitters are needed to send the information. Neurotransmitters...

... EMOTION: SEROTONIN, AND LIMBIC SYSTEM 2 Abstract This report will review how emotions control our behavior; focusing on serotonin physiology, and the role of the Limbic System. I will report the role of serotonin and physiological changes in the body affecting the emotions of an individual, as well as other symptoms that will be dully noted in the report such as depression. The Limbic System controls the physiological changes which affect impulse control, anger and aggression, among other emotions and behaviors—I will summarize the relation between activity and several disorders. Studies have been done to understand serotonin and physiology in humans, and medications that can increase serotonin activity to offset negative affects (Hariri and Brown, 2006, p. 12). This report will summarize the details of how serotonin, and how the Limbic System affects human behaviors. EMOTION: SEROTONIN, AND LIMBIC SYSTEM 3 Emotions: The roles of serotonin, and limbic system Emotions are generally defined as a state of mind that may reflect joy or fear, although, emotions also consist of patterns of physiological responses that lead to specific behaviors, which is what this paper will reflect. Specifically, the physiological responses of behavior are a direct reflection of how serotonin and the various areas of the Limbic System affect an individual. Imbalances of one or all three of these...

...while simultaneously the repertoire of behaviors not related to drug seeking, taking, and recovery, declines dramatically."(1) Recent scientific research has shown significant causal relationships between drug addiction and genetic predisposition as well as between addiction and environmental factors. Both genetics and the environment influence the brain, which in turn effects the behavior of usage. Once an individual begins using psychotropic substances, such as cocaine or heroin, measurable changes in brain chemistry and physiology perpetuate the cycle of addiction. Thus, we have an example of brain affecting behavior, which in turn, affects the brain. This cycle is particularly extreme and insular in the situation of drug addiction where free will and decision making are quickly and severely impaired. In this paper, we will first explore the genetic and environmental theories on drug addiction. We will then investigate how the behavior of drug addiction changes the brain to perpetuate the circle of cause and effect between the brain and behavior. Genetic Influences on the Behavior of Drug Addiction: Addiction does not result from a single gene. However, multiple genetic trends have been identified as crucial contributors to the illness of addiction. Alcoholics and cocaine addicts often express the A1 allele of the dopamine receptor gene DRD2 and lack the serotonin receptor gene Htr1b. These genes both fit into the pleasure-response category, but there are numerous ways...

...the belief that behaviors can be measured, trained, and changed. (1) Behavior is the response to stimuli. It is mainly concerned with observable behavior, not internal events such as thinking and emotion. Humans learn behavior from their individual environments through classical and operant conditioning. Classical Conditioning. Classical Conditioning is “the alteration in responding that occurs when two stimuli are regularly paired in close succession: the response originally given to the second stimulus comes to be given to the first” (2). Pavlov’s Dogs. Ivan Pavlov was a Russian physiologist in the 1890s who did studies on dogs creating “Pavolovian Conditioning” also know as classical conditioning. In his studies he began to look at the correlation between dogs salivating in response to being fed. A dog salivating in response to being fed is not a learned trait but a reflex. The dog salivating is an unconditioned response, which means it requires no learning (3). Pavlov started measuring the salivation secretions in response to being fed (3). Through his studies Pavlov saw that any object or event that the dog associated with being fed would make the dog salivate. “Classical conditioning is "classical" in that it is the first systematic study of basic laws of learning / conditioning” (3)....

...The way the cerebral cortex is organized is through different regions that receive and analyze the sensory information. The first is the primary visual cortex, also called the striate cortex, which receives the visual information. The primary visual cortex is located in the back of the brain in the occipital lobe. Then there is the primary auditory cortex which receives the auditory information. This cortex is located in a fissure (a major grove in the surface of the brain) that’s on the said of the brain or in the temporal lobe. Next is the somatosensory cortex which is responsible for receiving the information from the body senses. This cortex is a vertical strip in the brain that is located in the parietal lobe of the brain. Last is the...

Write a 350- to 700-word response to the following: Explain the communication process of neurons in the brain. List some common neurotransmitters and describe their effect on behavior. The communication process of neurons in the brain A brain of an average human contains approximately 100 billion nerve cells or best known as neurons. Neurons perform as information transmitters and receivers to other neurons or to muscles in the body. Neurons have these tiny fibers that extend from the body of the cell and its main function is to receive incoming messages and transmit them to the main cell. Outgoing messages to other neurons and muscles or glands are carried out by a single long fiber called the axon. Axons are covered with a white fatty tissue called myelin sheath. The myelin sheath provides insulation to avoid signals from other neurons to interfere with each other and it also increases speed when signals are been transmitted. Motor neurons carry messages from the spinal cord or the brain to the muscles and glands. Al l neurons in the nervous system only speak one language ON or OFF electrochemical impulses. The communication process of neurons in the work by impulses or what it’s also called firing. When a neuron receives a message from other neurons it automatically excites the neuron or tells the neuron to fire. This term...

Example: smiling, crying, running, hitting, talking, and touching. • Behavioral data (p.5): Are reports of observations about the behavior of organisms and the conditions under which the behavior occurs. • Behavioral neuroscience (p.14): Neuroscience is the study of brain function; behavioral neuroscience attempts to understand the brain process underlying behaviors such as sensation, learning, and emotion. • Behaviorism (p.13): Has yielded a critical practical legacy. Its emphasis on the need for rigorous experimentation and carefully defined variables has influenced most areas of psychology. The principles of behaviorism have been widely applied to human problems. • Behaviorist perspective (p.12): Seek to understand how particular environmental stimuli control particular kinds of behavior. First, they analyze the antecedent environmental conditions; then they look at the behavioral response, which is the main subject; finally, they examine the observable consequences that follow from the response. The behaviorist perspective was pioneered by John Watson, who argued that psychological research should seek the laws that govern observable behavior across species; and B.F. Skinner extended the influence of behaviorism by expanding its analyses to the consequences of behaviors. • Biological perspective (p.13): Guides psychologists who search for the causes of behavior in the...

...As we continue the discussions about human behaviors in psychology. I noticed that our behavior is influenced by many factors. And one of these factors is biological or physiological. Biologically, our nervous system is the most complex and elaborate system in our body. The nervous system regulates our behavior in order for us to survive. During the discussions I found out that our nervous system is composed of more than 500 million of nerve cells or neurons. These neurons or nerve cells are very important in our body. These are responsible in receiving stimulus or information from the environment then carries it to the brain wherein the brain itself interprets the stimulus in order for us to produce responses accordingly. Without these neurons, we could not coordinate our responses, nor could we perceive, feel or think. But the most important part of our nervous system is our brain because it is the one responsible of all voluntary and some involuntary behaviors. And it is the most intricate, complex and unique mechanism of the human body. So in order for us to have a remarkable behavior, we need to protect and take good care of our brain. In the midway part of the discussions we tackled about Sensation and Perception. This so-called Sensation also affects or influenced our behavior. Through our senses or sensory organs, we come to know our world and what we sense often affects our behavior. Our sense organs are responsible in sensation. And one must be aware or conscious of...
