Question

Quizplus · Accepted Answer

In monkey hand grip experiments, neurons that respond to the specific grip being used will be activated when the monkey reaches for the object. This has been demonstrated through the use of single-neuron recording techniques. The monkey's ability to reach for the object correctly is not dependent on being able to see it in the dark or having his attention redirected to it, as demonstrated by the experiment design.
