Seeing without Sight
Jessica Wurtz
The brain and the rest of the nervous system is a vast network of neurons, synapses, potentials, and many other critical parts that we might not ever understand. Just when we think we have finally figured something out about it, it seems that there is always something that contradicts the so-called scientific facts. One of these curious phenomena is that of how a human being uses their senses to perceive the surrounding environment. Since we are young, we are taught we have five basic senses: sight, sound, smell, touch, and taste. While this seems cut and dried, there are circumstances that are a source of confusion, such as when a person is deaf or blind. Being deaf or blind completely changes the way a person perceives the world and their surroundings. Often times, the other senses will become much more sensitive, as if to make up for the senses that are not functional. While it seems natural for this to happen, such as a 3-legged dog who runs just as well as any other dog, a closer look proves that it is not as simple as that.
