This is a test of the olfactory senses. Olfactory senses (sense of smell) are due to the olfactory cells being activated by odiferous molecules coming in contact with the olfactory vessels located in your nasal cavity. The nasal cavity is a tube that functions as a pathway that leads odiferous molecules to the olfactory epithelium. This epithelium is made of three different types of cells. The first type of cell is a basal cell, a stem cell that can later form into the receptor cells that line the nasal cavity. The second type of cell is called a supported cell, a cell that contains microvilli and secretory granules. The third type of cell is the receptor cell, neurons that receives a sends the signals activated by odors. (Vokshoor, 2013) The nasal cavity houses over one hundred million olfactory receptors. These olfactory receptors have the ability to recognize and distinguish approximately ten thousand different odors. One olfactory receptor has the ability to recognize ten different odors. When an olfactory receptor comes in contact with an odor the neuron within the cell excites. The neuron sends a signal to neurons in the olfactory bulb. Large amounts of chemicals bind to a wide variety of receptors. Multiple receptors can recognize a single odor. Combinations of receptors recognize different odorants. The identity of different odors are encoded, or represented, by a “Combinational coding scheme”. (Vokshoor, 2013) Each of these receptors send messages to the olfactory bulb where the scent is recognized. The olfactory bulb is located inferior to the frontal lobe. This bulb contains several synaptic layers. (Vokshoor, 2013) The olfactory senses have been a large part in survival for animals in the past and present.

It also tested which fragrances were the easiest and most difficult to distinguish, as well as if gender played a roll in distinguishing scents. It was found that humans are indeed capable of distinguishing between artificial and natural scents. The results showed that women have a stronger ability to distinguish a difference in scents than males. Works Cited Melville, Kate, Rusty Rockets, and Will Parker.

Most pheromone based perfumes marketed on the internet elicit their effect by affecting one or more gland in the body.
Tape Flashlight Cotton swab Tuning fork Tongue depressor Ruler. Procedure- I did a series of behavior tests on my partner Jazmine Cooley to test her cranial nerves functions; I started with her olfactory nerve, I told her to close her eyes and I placed the container of substance under her nose, I told her to inhale through one of her nostrils and then I did the same procedure with her other nostril. Next, I tested Jazmine’s optic nerve, which we walked over to the standardized eye chart and I told her to close her right eye so she could use her left eye to do the vision test. I also used a ruler to point at each letter as she read out loud what letter she could see.
In Lynda Barry’s Common Scents, she considers scents a demon for many reasons. One reason being that everyone has his or her own scent preference and scent in general, yet we also judge the way that other people smell. When the woman whose house smelled like a fresh bus bathroom talking about the smells of different Asian people’s houses, Lynda notes that she was “free with her observations about the smells of others” (18). She sprays her house with disinfectant sprays and air fresheners, which to her smells better that whatever her house smelt like before, but to others, such as Lynda’s grandmother, these smells are too strong and are trying to hide the fact that not everything smells good all the time.

This paper aims to endorse physicalism over dualism by means of Smart’s concept of identity theory. Smart’s article Sensations and the Brain provides a strong argument for identity theory and accounts for many of it primary objections. Here I plan to first discuss the main arguments for physicalism over dualism, then more specific arguments for identity theory, and finish with further criticisms of identity theory.
Natural body odor attributes from secretions of sweat, urine, saliva, and genital excretion. Personality traits such as neuroticism, extraversion, and dominance elicit associations with ones body odor. The olfactory system has the ability to learn quickly. With that being said, repeated emotional experiences may create a scent in response to the under or overproduction of secretions making that emotion or trait detectable to others. For example neuroticism is defined as the tendency to experience anxiety, nervousness, fear and easily upset. Emotions that stimulate and sustain the sweat glands customizing ones own personal neurotic aroma.

Scent is part of the five senses that are developed when an infant is still in the mother’s womb. It is processed by a part of the brain that correlates with memory, so at a young age an infant could differentiate who their mother is by scent. Odor is a sign and olfactory condition (Waskul & Vannini, 2008). As someone gets older they begin to develop scents they like and dislike. There are also scents that people find attractive and unattractive. When meeting another individual for the first time a human’s first instinct is to smell them without realizing it. For instance, have you ever sat by someone or hugged someone who smelled good or bad? If so, many people tend to associate the scent with attractiveness or unattractiveness depending on the level of smell. There have been many studies indicating that there is a strong correlation between odor and attractiveness. Although the scent is a universal and an undetectable smell it can influence the level of perceived attractiveness of another person.
Chicanos’ incorporation into the U.S. has been plagued by discrimination. Chicanos have been systematically oppressed, but they have not let themselves be victimized. Chicanos have not succumbed in the face of oppression, but rather resisted their incorporation into the United States. The Chicano Movement empowered the people to seek change in the inequality imposed on them. Much progress was made economically, politically, and socially in the movement, and now after the movement art continues to forge this identity of resistance in the U.S. Chicanos’ resistance and progress is evident in the film and media industry and in the reclamation of their cultural identity.
The author reminds us of how our nose smell good odor by saying “and now it is the souring flowers of the bedraggled.” (par.5); the odor of flowers are most of the time good odors and make us feel good. When I feel bad sometimes, I find a flower and smell that flower because it does make me feel good and make me forget about my problem for a moment. Although, the author mostly questioned why our nose have to
Olfactory codes are very difficult to study and motor codes are not studied at all. These codes seem to be transitory and the info driven is encoded in the visual way or a linguistic way…
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
From laundry detergent to perfume, room sprays to breath mints, everything now has a chemically produced scent to disguise the natural; modern culture has declared the embarrassment linked with body odor. On a night out or at a first date, men and women are both spritzing cologne and perfume and popping in chewing gum in an effort to smell pleasant and non-verbally communicate a message to the other. They are attempting to present themselves in a way they believe will appeal to the other and enhance the relationship. However, this very act proves that odors have the capability to affect our mood, perception, and
Recent research by Holland, Hendriks and Aarts (2005) has evaluated the effects of odor perception on behavior. According to Holland et al. (2005) associations may be formed between odors and other sensory information. In their research, they explored whether associations that are activated upon odor perception would shape behavior outside of the participant 's awareness. For the experiment, Holland and colleagues tested the hypothesis that exposure to a scent commonly found in all-purpose cleaners would influence a cleaning behavior from the individuals exposed to the scent (the prime).
The five senses of sight, hearing, touch, taste and smell are all sensations throughout the human body. Sensation is the involvement of sensory receptors as well as the central nervous system in order to allow us to experience outside stimuli. The system that allows us to experience sensation is the sensory system.
