In the context of a simple neural circuit that responds to motion, direction and speed tuning of neurons:
A) results in inhibition of firing when a stimulus with a direction of motion near the preferred one is used.
B) produce firing in a discontinuous manner.
C) are all-or-none events.
D) have a gradual falloff from the preferred direction or speed to nearby directions or speeds.

Question

Quizplus · Accepted Answer

Direction and speed tuning of neurons typically exhibit a gradual falloff in firing rate from the preferred direction or speed to nearby directions or speeds, rather than an all-or-none response or inhibition for near-preferred stimuli. This allows the neural circuit to encode a range of motion directions and speeds with varying degrees of activation rather than a binary response.
