A microelectrode is inserted into a neuron within the primate visual system. Various stimuli are presented to the eyes and changes in firing rate are recorded from this visual system neuron.
The part of the visual field to which a neuron responds is termed the
A) magnocellular visual system.
B) parvocellular visual system.
C) striate response field.
D) tuning curve.
E) receptive field.
Question 2
Which of the following is an explanation for the higher acuity of the visual system at the fovea, relative to the periphery of the retina?
A) A foveal ganglion cell may receive information from a single photoreceptor, whereas a peripheral ganglion cell may receive information from multiple photoreceptors.
B) The fovea contains only rods which are directly connected to the ganglion cells.
C) The foveal photoreceptor cells contain more photopigment per cell.
D) Peripheral photoreceptors are more likely to be damaged by prolonged light exposure.
E) Peripheral photoreceptors require greater activation in order to provoke a visual response.
