Neural circuits that enable the determination of direction and speed of motion by delaying input from one receptive field, to determine speed, to match the input of another receptive field, to determine direction, are known as ______.
A)phi-motion detectors
B)amacrine cells
C)threshold analogs
D)Reichardt detectors

Question

Quizplus · Accepted Answer

Neural circuits that delay input to determine speed and match input to determine direction are called Reichardt detectors. Therefore, choice D, Reichardt detectors, is the correct answer. Choice A, phi-motion detectors, are neural circuits that respond to apparent motion but not to determine direction and speed of motion. Choice B, amacrine cells, are a type of retinal cell involved in lateral processing. Finally, choice C, threshold analogs, does not have any significance in this context.
