Chemical Senses

A key piece of the odor emotion relationship comes from the ability to remember odors over time. Odor and memory have been studied at great extent and tends to overshadow the

Smell, on the other hand, is the sense that comes from odor molecules attaching to the olfactory nerve. Air carries the odor into the nose. Then odor contacts the olfactory nerves at the top of the nasal passages. The the olfactory nerves send a signal to the olfactory bulb of the brain, and the nerve sends a signal to the front of the brain. The forebrain translates the signals of the odor into a specific smell (Swindle, Mark).

Tastes and smells are the perception of chemicals in the air. The close relationship with smell and taste helps people perceive the flavors of food. Anyone with a cold has experienced that moment where they can not perceive the flavors of food because their smell has been “impaired” due to a stuffy nose. Taste itself is focused chemicals that have sweet, salty, sour, bitter, or savory taste. “The sense of taste influences food

* Sense of taste helps you to decide whether the food is eatable or not. Sensory organs in tongue helps us to decide what we like and what we do not

The fact that smell is really good at tracing back the memories and makes us remember to the time we were there. Marketing played a big role when someone ingenious thought of using a smell to attract consumers to come into a store because it just make them want that same feeling as before. A good example of this is going to the movie theater. What is the one particular smell that come in mind when going to the movie theater? Popcorn, when you enter the building your initial thought is the movie you are going to watch and if you are going to buy some popcorn. The emotional feeling when I smelling popcorn is the excitement, hyped, and happiness. Even without physically going to movie theater the smell of popcorn I would generally think of the last time I watched a movie while eating

It’s the smell of your grandma’s house, the scent of wax crayons and Elmer’s® glue, the aroma of your favorite home-cooked holiday cookies that your mom baked only once a year when you were a kid. Smells and odors have a natural tendency to transport you back to the rose-colored years of your childhood. Before you know it, you’re suddenly caught up in thoughts of who you were and how you’ve changed or perhaps reflecting on which decisions brought you to where you are in that particular moment in life. It’s in that moment, those short-lived moments, that one deeply appreciates the ability to smell and maybe wonders how such an arbitrary smell can have such a strong emotional response. Most of the scents that have strong emotional connections, nowadays, originate from inside of buildings and houses, just as most of the population lives indoors and spend most of their time in their homes or office buildings or schools.

Sensory processing develops naturally and is done without effort (What is, n.d., para 2). The brain’s “ability to process and organize sensations begins to emerge in the womb and continues into adolescence” (Bolles, 2001). “The human body takes in sensory input from several different sensory systems, organizes it in the brain for functional use, and then sends out signals to the rest of the body to activate” adaptive response (An Introduction, 2014). There are eight sensory systems found in the human body (SPD, n.d, para 1). Five of the eight sensory systems are known as the

“Chew like you’re chewing gum” my mom yelled as she demonstrated.  It had been a long journey and I just wanted to stop and rest when several delicious aromas traveled into my nose and caused my stomach to growl as if I hadn’t eaten for three days.  Following it was a scent of well done burgers with melted cheese and a side of mouthwatering, crunchy fries.  The smell of freshly roasted coffee was everywhere and it was so calming to me because it reminded me of home.

My childhood tasted luscious syrupy the pancakes with the butter.I also have tasted the sourness of the candy that had sweetness to it for i was eating sour patch kids.I also had one that the taste was sour the kind of sour that makes you a funny face this was the taste of sour skittles.The delicious apple pie the sweet taste the gooeyness of the filling.The strawberry wafers the the taste was not like strawberry but something different.The peanut butter cookies the taste so similar to the ones that come in the plastic jar.The sweet taste of the chocolate shell and the chewy peanut butter in the inside the M&M’s.The bitter taste of the medicine the taste sour horrible you want to spit back out the taste is something that is hard to describe.The

Studies published in Chemosensory Perception show individuals with psychopathic traits may also have a weak sense of smell. The article ‘Psychopaths’ Have An Impaired Sense Of Smell, Study Suggests, which was published in Science Daily, has studies done by Mehmet Mahmut and Richard Stevenson in Australia. Previous research shows that the area of the brain dealing with empathy, something psychopaths do not use, and the olfactory sense are relatively near each other in the frontal cortex. The scientists took 70 non-criminal adults who volunteered for the study and began with assessing each participant’s accuracy and sensitivity to smell. Afterwards, they measured the individuals’ psychopathy levels. They did this by asking a series of questions

At first I was trying my best to just look at the optical illusions and move the bar to the right spot or choose the correct answer, but I quickly realized my naked eye was faulty.

The process of smell in medical terms is called Olfaction. The olfactory system allows the brain to detect odorants, or chemicals in the air, that turn into signals which our brain can then use and interpret. Every smell has its own emotional response that triggers a memory. Certain smells can lead to different responses such as the need to fight or flight in the event of an emergency. When you smell something that gives you a memory, you do not think about how the scent is taken to your brain; it just happens. It is actually a very complicated process that involves many pathways and receptors that all reach back to the command center of your body; the brain (Amerman, 2016).

“Taste, like smell, is a doorman for the digestive tract, a chemical scan for the possible dangerous (bitter, sour) elements and desireable (salty, sweet) nutrients.” (46)

Or a dish that didn't turn out right the first time you may have cooked it. These memories are called the Proust Effect. The Proust Effect is elicited memories that are connected from structures involved in both taste and olfaction to the amygdala, which is involved in emotional behavior. And to other structures such as the hippocampus which is involved in storing memories. When we smell certain odors or aromas it activates the amygdala and elicits emotional memories. I can remember my first time eating Korean food and every time I see or smell it being cooked, I think about that time. Some of our memories may not be so pleasant though. You may remember a bad memory of a certain food that you may smell. I know for me every time I smell fire or taste the dust from the air, I think back to the Iraq deployments. So some things that you taste and smell will take you back into that head space. You may lost for a moment because you are in that moment at that time.

It makes up a majority of the human body, covers a majority of our planet, and is in limited supply in California at the moment. Can you guess what it is? Water! Water is the life-giving substance that nourishes our bodies as well as the plant life here on Earth. Almost all of us have sat next to a quietly babbling brook, listening to the sounds, feeling the cool breeze blowing over the water, and watching as it rippled over the stones. Some of the happiest summer memories are those of diving through cold ocean waves, and feeling the water rush around us. Water is such a powerful force, and it widely known for its life-giving properties.
