Our visual acuity will be best when a ganglion cell
A) transmits its neural signal directly to the visual cortex.
B) has a small receptive field.
C) has a large receptive field.
D) transmits its neural signal to the cerebellum, instead of the visual cortex.

Question

Quizplus · Accepted Answer

Ganglion cells with small receptive fields allow for greater visual acuity because they respond to only a small area of the visual field, providing more precise information to the brain. Ganglion cells with large receptive fields provide less precise information and are important for detecting overall patterns and movements in the visual field. Transmitting the neural signal directly to the visual cortex (A) is necessary for visual processing, so this does not affect acuity. Transmitting the signal to the cerebellum (D) would not be involved in visual processing at all, so this also does not affect acuity.
