How Does it Feel: A Study in Sensory Perception

Sensory stimulation is a chemical process which occurs between the benevolent body and wag. When we let sensation, our body is exposed to some image of sensory stimulation. The sensory receptors then receive this information, and transmit it to the brain using neural impulses, or neurotransmitters. There it is examineed into the shew sensation. Sensations are the basic building blocks of perception. Perception is the process of organizing and reservation sense of our sensory input. Perception allows us to better interpret the information our sensory receptors receive, and form images of the world around us. Transduction is what happens when the receptors transmogrify the energies they receive into a form that can be interpret and utilized by the nervous system.

Human beings are able to experience various sensations because the nervous system encodes the messages we are receiving and interpreting. In his dogma of ad hoc nerve energies, Johannes Muller theorizes that polar sensory modes exist because the information received by our sensory receptors stimulates different synapses when travel back to the brain. This is known as anatomical encode. This type of encode determines which sensory organ is activated by a accredited type of stimulation, according to which particular neural pathway it travels. (Wade, Tavris, 2006).

Anatomical encoding does not totally explain how or why our different sensory modalities exist independently.



Scientists found it difficult to link specific skin senses to individual neural pathways; neither does the doctrine of specific nerve energies explain variations of stimulus within a certain(a) sensory experience, i.e. the softness of an animals fur versus the coarseness of sandpaper, or the differentiation between the colors light blue and dark blue. A second type of encoding, called functional encoding, is therefore required to make sense of these differentials in our sensory perception. According to Wade and Tavris, functional...
