What Are The Five Senses

How Outside Stimuli are affected by the Five SensesAP1 ProjectShelby HardenSo, many things use the 5 senses. Each sense controls something different. Without having one of the five senses, can turn your whole life around. Treasure them all. Each function provokes every step you take in life. Outside stimuli can be received by the five senses which are sight, sound, touch, smell, and taste. Sight is very important to everyday life. Light waves off an object is what lets us see. The brain connects the light wave to memories or what it might be associated with, which then allows us to precept what the object is. This process happens so fast, you never see it coming. The stimuli you get from seeing is the colors the make an object and projects feelings. Sound is precious.

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

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

Smells trigger memories on an emotional level. We, as humans, have a stronger emotional response to odor triggered memories than any other sense. Smells of a perfume or a ripe banana brings back memories of old. As for new experiences, memories consolidate in our sleep. Even though it is not known what stage of sleep this consolidation occurs, plenty of research qualifies this idea. In the research article “Sleep Supports Memory of Odors in Adults but Not in Children,” Prehn-Kristensen, Lotzkat, Bauhofer, Wiesner, and Baving put these areas of memory together and conducted a study in sleep consolidation involving the recollection of smells.

This whole process is what then initiates a neural response. Our odorants act on more than just one receptor but does on different levels. Also, a single receptor will interact with more than just one different odorant on again many different levels. This means that each odorant has its own pattern on which it acts, this all being set up in the sensory neurons. From here the patterns of activity are then sent to the olfactory bulb. This is where the other neurons are then activated, done so to form a unique spatial map of the odor. The neural activity we experience is then created by this stimulation and passed on to the primary olfactory cortex that’s located at the back of the underside or “orbital” part of the frontal lobe. Finally, the olfactory information is then passed on to adjacent parts of the orbital cortex where the combination of odor and taste information help to create the perception of flavor!

First, the axons carry the stimuli to the olfactory bulb where the axons and dendrites synapse at the mitral cells. The stimulus then travels from the bulb to the primary olfactory cortex which is responsible for identifying the scent. Neurons within the olfactory cortex relay information to parts of the limbic system. When the smell is processed it triggers several reactions such as emotional responses or even memories. Then process of olfaction is not as simple as smelling an odor and receiving a response; the odor must travel through pathways and stimulate receptors in order for the brain to interpret it (Amerman,

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).

Smell can also play a crucial part in the development of babies. Very soon after a baby is born, the baby can identify its mother by its mother's scent. Something that I stunned me about my sense of smell is that, one of many scents can trigger a ton of memories. This stuns me because although this happens all the time, I've never actually thought about it. It was also interesting to be informed that one average odor can have more than one molecule. The sense of smell interacts with the brain similarly to the way that vision does.

Perception is how an organism detects and interprets the external world. There are five senses - smell, taste sound, touch and sight. Of the five senses, sight is highly complex and requires the largest proportion of total brain power. The brain dedicates much of the cerebral cortex, directly and indirectly, to support visual processing with senses like proprioception and memory (Al-chalabi, Turner, & Delamont, 2006).

Our brain is completely isolated from the rest of the world. The only way one is able to use his or her brain is to use the body’s senses as a way to send messages to it. Humans have five recognized senses that are responsible for giving our brain vital information. These senses are one’s taste, touch, smell, hearing, and vision. While these senses are highly important to our daily functions, the Senses Challenge has shown me how unaware we are of how complex they really are.

The function of the sensory neuron is to carry around action potentials from a sense organ or receptor to the central nervous system. The structure of the sensory neuron has the sensory receptors, the structure of these are that they vary however they utilize the gated sodium ion channels which are present in the membrane. The function of these are that they are able to detect a change in the environment and they are able to create an action potential with sodium ions. The schwann cell wraps around the axon and is used to insulate it from the myelin sheath. The cell body is in a ganglion which is close to the CNS. There is also the axon, this is short communication route which is between the cell body and the axon terminals, in this there

Smell is based on sensors that detects different chemicals. “Your ability to smell comes from specialized sensory cells, called olfactory sensory neurons, which are found in a small patch of tissue high inside the nose. These cells connect directly to the brain. Each olfactory neuron has one odor receptor.”2 The sensors go off and then its sends a message to your brain. “Once the neurons detect the molecules, they send messages to your brain, which identifies the smell.”2

Choose any one of the five senses. What one aspect of that sense could be important from a psychology point of view?
