Document Summary

Synesthesia: mixing of the senses i. e. sounds as colours or tastes as touch sensations. One theory is that the pruning of neural connections that occurs in infancy has not occurred in people with synesthesia, so that brain regions retain connections that are absent in most people. Another theory is that with synesthesia, there is a deficit in neural inhibitory processes in the brain that ordinarily keep input from one sensory modality from overflowing into other sensory areas and stimulating them. Sensation is the stimulus-detection process by which our sense organs respond to and translate environmental stimuli into nerve impulses that are sent to the brain. Perception: making sense of what our senses tell us is the active process of organizing this stimulus input and giving it meaning. Some species have different senses that human don"t have, it"s all due to adaptation to the environment. Transduction is the process whereby the characteristics of a stimulus are converted into nerve impulses.
