Question

For (a) taste, (b) vision, and (c) hearing, write the pathway of the action to the specific brain region responsible for interpretation of the sense. The pathway for olfaction is listed as an example Olfactory - olfactory nerve (CN 1) - olfactory bulb - olfactory tract - primary olfactory cortex (in frontal lobes) For (a) taste, (b) vision, and (c) hearing, write the pathway of the action to the specific brain region responsible for interpretation of the sense.

Explanation / Answer

(a) Taste - CN 7, 9, 10 - nucleus tractus solitarius - medial lemniscus - ventral posterior nucleus of thalamus - thalamic radiation - face area of somatosensory cortex - anterior part of insula

(b) Vision - rods and cones - bipolar cells - ganglion cells - optic nerve (CN 2) - optic chisma - opic tract - lateral geniculate body - optic radiation (geniculo-calcarine tract) - visual cortex (occipital lobe)

(c) Hearing - CN 8 (auditory division) - dorsal and ventral cochlear nuclei - inferior colliculi - medial geniculate body - - auditory cortex (temporal lobe)
