Question

Quizplus · Accepted Answer

Optogenetics is a technique that involves genetically modifying neurons to respond to light, allowing researchers to precisely control the activity of specific neurons in the brain. This technique has been used to test the hypothesis that the activation of engrams (groups of neurons that store specific memories) is necessary and sufficient for the expression of a memory. By selectively activating or silencing these engrams using light, researchers can determine whether the activation of a specific engram is capable of eliciting the behavioral response associated with the memory. Therefore, optogenetics provides a way to test the requirement that the activation of engrams must activate the behavioral measure of the memory.
