Document Summary
Tm suggestions: know the names and functions of all of the receptors in the skin (summarized in figures 8. 4, 8. 13, 8. 14, and 8. 22), and their pathways towards their highest level of processing in somatosensory cortex (figures 8. 15. 8. 23, and 8. 27). conceptually crucial part of this chapter to understand is summarized in figure 8. 8. Sensory receptor organs detect energy or substances: all animals have sensory receptor organs, they detect/respond to certain stimuli. Ie study with a monkey, finger got cut off, and as a result area in brain that controlled the 4 remaining fingers changed (to compensate for the extra brain space the 5th finger was using up) Ie study with another monkey, conditioned it to learn to access food by tapping. 2 fingers on a thing, over time the area in the brain corresponding to those 2 fingers enlarged and were bigger than areas the other fingers took up. Dermatome: strip of skin innervated by a certain spinal nerve.
