The Human Sense Of Smell

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).

Senses airborne chemical molecules • Related to memories & emotions • Consists of 10 million rods embedded in the olfactory epithelium – responding to different chemicals

Smells connection to emotion was also discussed, it turned out to be molecules with receptor signals capable of triggering memory through the olfactory part of our brain and the hippocampus, the site of memory

Ani Lui explained the importance of smell and how we can use it to fix are problems in life. “Nothing is more memorable than a smell. One scent can be unexpected, momentary, and fleeting, yet conjure up a childhood summer beside a lake in the mountains” (Diane Ackerman).On Ted Talk, Lui talked about how smell can be a huge resource to our everyday life.The show was called “Smelfes, and other experiments in synthetic biology”. She showed pictures of fruits like strawberries that could grow its own fruit. Ani Lui is from EIT lab, a designer. She sorts out science fiction and science fact. At their lab, they study artificial life and objects. Back in the 19-century women would put an apple under there underarm. If the man ate the apple that meant

- This study demonstrated that recollection of odor retrieval-cue brought about more familiarity and the ability to describe

Whenever I start to smell fresh cookies, I’m able to smell the chocolate melting. I’m able to smell the salt in the cookie, while my mouth begins to salivate. When I smell the cookies being baked it’s almost as if I can taste them. I know that as I grow older, whenever i smell cookies being baked, I’ll be able to remember from when I was

The articles, “The History of Stink”, written by Kristin Lewis, and “What’s that Smell?”, written by Kathy Satterfield, talk about how our hygiene’s practices have changed exponentially. To illustrate, the first article states, “The ancient Egyptians kept fresh by rubbing their pits with cinnamon and citrus oils. After exercise, the ancient Greeks scraped their skin with a metal tool called a strigil” (Lewis 18). This excerpt from the article helps explain how even since the begin of times, our ancestors changed their way of maintaining hygiene, from using cinnamon and citrus oils to scraping their skin with a strigil. Additionally, another portion of evidence from the second article says, “Now Clayton, 15, and Nicolas, 12, douse themselves

Under the mentorship of Dr. William Fifer, an expert in conducting high density, high impedance EEG to study learning and memory in human subjects, I will learn how to apply a combination of EEG analytic techniques and ANS function assessment to define and characterize odor-related oscillatory and dynamic electrophysiological patterns in the medial temporal lobe, where the primary olfactory neural system and entorhinal-hippocampal memory system are located. Under the mentorship of Dr. D.P Devanand, an expert of conducting clinical trials in Alzheimer’s disease, I will learn how to translate the findings from EEG and autonomic reactivity into high specificity

The smell receptors interact with the molecules of these vapors and transmit sensations to the brain. We need only a little amount of molecules of substance to trigger an impulse of smell in a nerve end, and we can smell more than ten thousand different scents. If it is a new scent it is possible to remember the scent and identify it again later. The scent captures one’s memory of the place; the nose makes the eyes remember. For the blind people, the sense of smell can help awareness of one’s location. Odour can also relate to hunger and the desire to consume. Since it is not possible to name all the odours, spatial qualities or experiences are often associated with scents. Positive experiences of smell can be used in design to induce positive memories or associations to a space, while negative smells can do the opposite. Bringing certain smells into a designed space can immediately stimulate emotions, guide us, or distract us. Designer Valerie Trent cites research that connects smell and memory; “People can often recall aromas from childhood or a distinctive odor they’ve only smelled once. Whatever your particular nose prefers, smells do enhance comfort and

Smell is one of the five basic human senses. Smell is a powerful sense with many abilities. Smell can alert people to potential dangers. Smell brings variety into the world. In addition to these, smell also has one very special ability. Smell can instantly draw memories out of a person.

Have you ever been to a place and have seen something or simply have smelled something that made you reflect on something that you witnessed when you were younger, or reminds you of a joke that you and your friends cracked up on the other day. Have you ever seen people walking down the street that look like people that you have seen before? Theses are called memories; memories often occur when you have done something and are remembered by the five senses touch, smell, sound, sight, and, taste. These five senses are the main reasons why you remember things, that have occurred in your past. Reflecting on things is usually measured on your first reaction, if you don't like something then all of your senses are gonna be negative towards that event, person, or place. For example, if you don't like the tangy and bitter smell of the salt from the ocean, then that's probably the only thing that you will remember of it. Understanding the core basics of your

The hypothesis for the dog’s experiment of sense of smell was rejected. The data used for the experiment does not support the hypothesis because testing each dog seven times gave both of the dogs both having an equal chance of winning four or more wins. The younger dog had the faster time with 1 min and 24 seconds, the younger dog had won 5 times and had its time decreased. The older dog started off with the time of 1 minute and 55 seconds and decreased too. The older dog won 2 times out of 7. The average of each day is 53 seconds. I think the data turned out the way it did because the dogs are two different ages first of all. I thought that the older dog would have a better chance because of being older and wiser but she only won 2 out of 7 times. A couple outside factors that I think could of changed the experiment are having the dogs go outside before the experiment, shutting a door so they couldn’t see the treat being hidden, or if they had been eating before the experiment started and where food was already on her mind. I think using a stopwatch changed a lot of things because it took longer and made the data table round. I think that there were many outside factors but the list would be two long to list.
