Question

Given your current lifestyle, describe what your sensory homunculus would look like, and explain why- making reference to tactile sensation.

Answer 1

The most common homunculus model is a 3-D representation of the amount of nerve space our vaious body parts take up in the region of our brain which is devoted to feeling. We can see some proportion out of shape which depict areas that are provided with more information from certain parts of our body when copared to others. For example our hands required a high concentration of nerve endings as they perform all important activities on everyday basis as compared to our shoulder or knees. The amazing thing about homunculus is that it is constantly changing in response to our environment and how we interect with it. For example when we perform any series of activities, there are variety of nerve endings that pick up this activity & send information via nerve to the sensory areas of our brain, through which we can match what we plan to do & get assured that the assigned task is now finished. The more often we perform noble activities with our whole bodies, more stronger our sense become. b) Tactile sensation is the sense of touch which originates at the surface of the body​ other than internally. Nerve endings designed to act as tactile receptors are located in the dermis of the skin and send signals to the brain, which the brain then interprets as sensations. Tactile sensation gathers so much information that it is possible to fool the brain into interpreting information incorrectly.
