Taste, designed in part to help us reject harmful foods, has long served as the body’s primary defense against poison. As befits its role, the system is lightning fast: The body can ­detect taste in as little as .0015 seconds, compared with .0024 seconds for touch and .013 seconds for vision. To be tasted, food molecules must fall into a cluster of cells called a taste bud, more than 10,000 of which are spread over the tongue, palate, and inner cheek. The taste bud sends a signal to the brain, which then determines everything from whether a food tastes “safe”—which in most cases means it’s not too bitter—to whether we enjoy it. In a part of the brain known as the anterior cingulate, tastes get married to an emotional reaction: disgust for rotten meat, say, or delight for a sweet strawberry. But while some tastes are innate—nearly all humans are born with a sweet tooth—there’s also evidence that taste can be nurtured. Studies have shown that babies prefer foods they first “tasted” in the womb, or while nursing. (Traces of certain flavors, including garlic and vanilla, turn up in amniotic fluid, and also in breast milk.) More recently, food scientists have found ways to manipulate our likes and dislikes. One chemical, extracted from a West African fruit, binds to taste receptors in a way that makes even the sourest lemon taste as sweet as lemon pie. Food scientists have jumped on the discovery, scrambling to devise additives that would trick our taste buds into perceiving sweetness in the absence of actual sugar.

Chemical Senses Final

...Chemical Senses Julie Harris PSY/345 September 28, 2015 Adam Casteberry Chemical Senses Chemical sensory is the process by which the body experiences the world through the sense of smell and taste. The process the brain uses to perceive the smells and tastes that are introduced to it is through an electrical mapping of electrical impulses similar to the sense of touch, sight, or sound. Each sense is individual but through the interaction of each a more whole picture is produced that the brain stores as a memory. Most adults have their memories peppered with the smells and tastes that helped create those memories whether it was the first time a person was asked to be married, or the first time a person faced death, each experience is marked by a distinct taste or smell that will call up the memory and shape the person who holds it. The process of chemical sensory is conducted mainly through the nose and mouth through a bombardment of sensations is experienced throughout each day. Once considered separate from each other as either the nose or mouth people have become aware of the connection between the two senses as being tied irrevocably to each other. Chemicals in foods are detected by pallia that we have labeled taste buds, small structures in the mouth that are embed in the tongue, the back of the mouth, and the palate (Society for Neuroscience, 2012). Each person has a range of 5,000 to 10,000 taste buds that consist of 50 to 10 sensory cells that are stimulated...

Taste Talks

...A person’s choice of food always should be based on a sense of taste and pleasure. Taste is the most important sense among other 5 senses of a human body. And when it’s the time to decide for taking food, it should be based on a sense of taste, not rely on a sense of nutrition or food value. If a food is full of nutrition or food value, but doesn’t taste good then what is the meaning of taking that food? It is not a matter for doing anything; it is the matter of taking food. If my taste sense denies taking that food which is full of nutrition then it is useless to take that food. So, at the time of taking food, we always have to choose food on the basis of taste sense not rely on food value or nutrition. A food that tastes good is always good for health. Tasty foods also have good nutrition and food value. If we don’t support the taste sense then it is useless to take food. If we see our food habits we can easily rely on taste sense. As we are Bangladeshi, our main food is rice, and with rice we eat fish, beef, mutton, chicken etc. these items are tasty, but, if we just start only taking vegetables that would be tasteless few days later. Fish and meat also have nutrition. Besides these, we often eat burger, sandwich, rolls etc. that tastes good, and our body can consume those items. If we only think of nutrition and food value, we have to give up those items and only have to take vegetables or nutrition filled food items and our life will become tasteless. In our country,......

...Chemical Senses Eric Gunderson PSY/345 - Sensation and Perception June 27, 2016 Matthew Will Chemical Senses The five senses of human experience are well known to most everyone: we can see, hear, touch, taste, and smell. However, the science behind them is not as well known. The first three (sight, audibility, and touch) are senses in which external stimuli are perceived by a person through the by-product (i.e. reflection of light, pressure changes in air, pressure/stretching/vibration) of an environmental object. The latter two, taste and smell, are senses in which external stimuli have to physically enter into a person in order for him or her to experience the sensation. The sensations themselves are activated by chemical reactions from the external stimuli as opposed to light and pressure changes that the other senses employ. The chemical sensations smell and taste are interactively working together. The purpose of this paper is to describe in detail just this. The first thing that will be discussed is how smell and taste affect each other and which one of the two one would change to make a meal taste better, followed by a description of the sensory elements that must be present to emphasize the connection between the chemical senses, emotional memories, and the brain in order to make the most memorable meal of one’s life, and concluded by a description of the connection created between the chemical senses, emotional memories, and the brain. How Smell and......

...Chemical Senses Jenny McDowell PSY/345 04/18/2016 Adam Castleberry Chemical Senses Chemical senses are the connection of smell and taste. Different fluids and water are chemical substances that dissolve in the mouth that is a stimuli of taste. “There are four basic descriptions that stimuli taste, they are the following, bitter, salty, sour and sweet. These sensations can be combined to stimulate different types of stimulation of taste,” (Bartoshuk, L. M., & Beauchamp, G. K.) (1994), Chemical senses. Examples would consist of salt and vinegar potato chips, sweet and sour chicken, and other different combinations. Taste buds that are located on the tongue are called receptors, there are thousands of tiny bumps (taste buds) all around the tongue that are called papillae. Within each papilla there are many taste buds and information is conveyed by nerves, then to the thalamus and finally to the area of the cortex. “For smell, in humans the olfactory receptors work together to detect different types of smells, there are over 400 types of different sensors in the receptors of the olfactory,” (Monell chemical senses center; extensive variability in olfactory receptors influences human odor perception. (2013). The stimuli chemical substances are in the atmosphere, which as in a result the olfactory receptors are simulated by these substances. The receptors are located in the upper portions of the nasal passages. The olfactory nerve is formed when......

Sound and Smell

...sound wave that determines its loudness. The amplitude has to be loud enough for you to hear a sound. This amplitude varies by what type of species of animal. Loud sounds can injure your ears and result in loss of hearing. Sound can be affected by the direction and distance. You can detect the direction of a sound and where it is coming from. When you detect the direction of sound it is determined by comparing the sound heard by each ear. The detection of the distance is the most difficult step to sound; this is because it relates to the loudness and quality of the sound heard. Sound is made so you can hear the world and environment around you. The process of sound helps you understand the information that is being presented to you. Ears sense pitch and loudness; animals and humans can hear sound in different ranges. You can determine direction and distance...

Senses

...THE SENSES Hilgard morgan and Sartain explain that there are more than eight senses that we use to explore and learn about the world.Each of these senses has a specific sense organ within which are receptor cells or receiving mechanisms that are sensitive to certain stimuli in the environment. The Eye Is the organ of vision, is sometimes compared to a camera lens because it works roughly the same way as the latter which focuses images of objects at various distances o the film as it moves toward or away from the place of the film. The lens of the eye focuses light images on a sensitive surface.This surface in the eye is the retina,which is composed of rods and cones. Rods which are cylindrical and number about 100 million,do not distinguish colors but are more sensitive to light than are the cones. Cones which are conical in shape and more than six million in number,allow us to see the different wave lengths of light as different hues or colors. Hilgard presents the process of seeing,light enters the eye through the cornea,a tough transparent membrane.The amount of light entering the eye is regulated by the diameter of the pupil,a small hole in front of the eye formed by the iris.The iris consists of a ring of muscles that can contract or expand,thereby controlling pupil size. The Ear Is the sense organ of hearing which is sensitive to sound waves,the mechanical vibrations in the air. There are three parts of the ear:The outer......

Psychology

...Chemical Senses Paper It’s interesting to find out that the things we eat and drink are more so identified by our senses of sight and smell and not just taste. This is because food can be identified by just sight alone, and same thing goes for smell as well! Our brains actually view taste as a combination of the senses smell and touch at the same time. So really all sensory information is gathered from the actual substance we a consuming. The way we get this information through sent is located in the back of our mouths and called the “retronasal olfaction. The way we gather this similar same information through smell is located in the nose and called the “orthonasal olfaction”. These methods both influence the perception of flavor, so in this smell influences taste and taste influences smell! Taste and smell are classified under a chemical sensing system called “chemosensation”. The whole entire process of smelling and tasting starts when molecules, which are released from all of the many substances around us, stimulate special nerve cells in the nose and the mouth. These cells transmit messages to the brain, where specific smells or tastes are identified. Our body’s ability to sense chemicals is actually another chemosensory mechanism that contributes to our senses of smell and taste. In this system there are thousands of free nerve endings which are mainly located on the moist surfaces of the eyes, nose, mouth, and throat to identify different sensations. Taste and......

Chemical Senses

...Chemical Senses Robert J. Bernal June 6, 2016 Robert Levitt, Instructor University of Phoenix Intro The senses of smell and taste are chemically based senses that are unique to the other senses in the way in which the brain interprets them. Unlike other senses which are perceived and categorized analytically, taste and smell both pass through the emotional response center of the brain on the way to their being stored as memories, evoking an emotional association to their formation as engrams. Consider the unlikely association between taste and smell and the emotional response that they can trigger; a chemical reaction that gives off a gaseous “odor”, completely quantifiable by scientific standards, can trigger a purely emotional, unquantifiable response. The question then becomes, how do smell and taste play on our emotions? How do Smell and Taste Effect Each Other? The senses of smell and taste are integrally linked, the ability to do one without the other is not possible with the way that the brain is wired. Physiologically speaking, the way that humans are “designed” or the way that we have evolved is that the nose and the mouth are located in proximity to each other. This means that as we taste a food we are also inhaling particles that create the aromas that are generated by that food, and the brain’s interpretation of the stimulus from the taste buds along with the olfactory sensors in the nose is simultaneous; the memory engrams that form based on...

Human Sense Organs

...Tiffany Herring B. LaFond PSYC 1000 Human Sense Organs As human beings we have 5 different human sense organs. These sense organs are sight, smell, touch, taste, and hearing. Our 5 sense organs help each of us and how we perceive reality and the world around us. Without our sense organs we would have a much harder time understanding the world we live in. Each of our different senses have specialized organs that are set up to receive specific stimuli, these are linked to the nervous system and from the nervous system then linked to the brain. The first sense organ is sight. The eye is the organ of sight. The basic structure of the eye consists of a transparent lens that focuses light on the retina. The retina is covered with two types of light-sensitive cells called cones and rods. The cones are sensitive to light whereas the rods are not they have a greater sensitivity to light. The eye is connected to the brain by the optic nerve. Our brain takes the two different images from our eyes and turns them into a single 3-D image. One of the most amazing things I learned about the eye was that our eye actually sees things upside down but when our brain processes the images it sees it turns them right side up and that is the image our brain shows us. Smell is our second sense organ. The nose is the organ we use to smell. The nose is lined with mucous membranes that have smell receptors that are connected to the olfactory nerve. Smells are made up of a variety of......

...EXPERIMENTATION ON SIMPLE REACTION TIME (SENSES: REACTION TIME) Date conducted July 04, 2015 Introduction How do we know the reaction time of its senses? Which of the senses is more sensitive and very fast in receiving information? How do we read laboratory primers and organized data into summaries and graphs? We will find out from this experiment the sources of reaction time. We shall identify also the early programs of research on RT. We will compare which of the sense is slow or fast in receiving information. OBJECTIVES: -This experiment aims to acquaint us in reading laboratory primers and organized data into summaries and graphs. -This experiment aims to identify which of the senses is more sensitive and very fast in receiving information and which of the senses that is very slow in receiving information. -It sought to know the reaction time of its senses as well as the average reaction time. Background and Related Literature: According to studies such as those done by Brebner and Welford published in 1980, mean auditory reaction times are .14-.16 seconds and mean visual reactions times are .18-.2 seconds. The time it takes for the signal to reach the brain was also found by these studies; it takes auditory stimulus .08-.1 seconds to reach the brain while visual stimulus take .2-.4 seconds to reach the brain. Based on this information as well as that from the experiment, a new hypothesis and prediction were being proposed such that if it does takes......

Concept of Adaptation

...students to learn by firsthand experience. There are a few experiments that could be very interesting for them to do on themselves and others. The concept of adaptation is defined as “Diminished sensitivity as a consequence of constant stimulation ("Psych m.d. –," )” or “The tendency of a sensory system to adjust as a result of repeated exposure to a specific type of stimulus such as low levels of light ("Psych m.d. –," ).” An easier way to understand the concept may be to call it sensory adaptation. This explains in the name alone that it will be dealing with the 5 senses we have. Included in these five senses are taste, touch, smell, sight and hearing. I will be touching base on each sense and give you an example for each, before we continue on to our experiments. Taste is our first topic and one we will be working with later. We have thousands of little taste buds that allow you to “taste” four basic tastes including salty, sweet, sour and bitter. When you eat candy for example you could be eating skittles original flavors. While you are getting ready you separate the flavors...

...and it gives us a variety of different methods to interact with the world we live in. We receive information from the world via our senses. Each sense is distinct and different. Each sense provides us different experiences. Two people can be in the same situation but based on what they sense, they will each experience something different. Everyone relies upon their senses differently and some of the senses may be more accurate than others. I will discuss three reasons for believing in the accuracy of sensory data, three factors contributing to the accuracy of sensory data, and the role of memory with regard to the interpretation and evaluation of sensory data. Our senses act as our lenses, amplifiers, particle detectors, and pressure and heat gauges (Kirby & Goodpaster, 2007). Our sense of smell warns us of dangers, such as smoke or poisonous gases. It also helps us enjoy the flavors of our favorite food and drink. With our sense of smell receptors, we are able to detect thousands of distinct smells. Reactions to smells are rarely neutral; one usually either likes or dislikes a smell. Smells leave long lasting impressions and are strongly linked to our memories. Our sense of taste protects us from eating poisonous and unsafe foods. We are likely to spit out something that tastes bad, before it has a chance to enter our stomachs. Taste also helps us to maintain a consistent chemical balance in our bodies. For example, our liking sugar and salt helps to satisfy......

Sense Perception

...org/dialogue4kids/season10/senses/facts.cfm http://www.sciencemuseum.org.uk/WhoAmI/FindOutMore/Yourbrain/Whatareyoursenses.aspx We have 5 senses which are sight, smell, sound, taste and touch. They are very important in our lives because we would use one of them every moment of every day. They also work together to let our brains know what are going on around us, in other words, they are protector by warning us of any danger. However, any quick change to any of the five senses can cause the feeling of dizziness or unsteadiness. You might have experienced this while riding in a car or turning quickly. Sight: Eyes are the organ of vision. The function of our eyes are the same as cameras, as we can see images from the world and send information to our brain. Then, the brain processes the information, therefore we can see movement, color, depth and shape. Sound: Ears are the organs of hearing. The function of our ears is collecting sounds, and hearing helps us to learn and communicate to others. We can hear a huge range of sounds, from a deep bass to a high-pitched whistle and those sounds will change into electrical signals to the brain to process. Therefore, the brain uses the sounds from left and right ear to determine distance and direction of sounds. Taste: Tongue is the organ of tasting. The function of our tongues tastes four different flavors, which are salty, sweet, sour and bitter. We have 10,000 taste buds spread over the tongue, and each of them contains 100......
