2 (d) serotonin, Parkinson's disease (e) glutamate, synaptic transmission in retina ____ 7. Which of the following observations about neuronal responses is NOT correct: a. cells in inferotemporal cortex respond to complex images such as a hand or face b. cells in parietal cortex respond to both tactile and visual stimuli c. a cell in auditory cortex responds at a higher rate when sound at one frequency is delivered to both ears simultaneously than when delivered to either ear alone d. cells in visual area V2 (area 18) require BOTH auditory AND visual input to fire e. cells in middle or superior temporal cortex respond to visual stimuli moving in a particular direction ___ 8.
