Question

Quizplus · Accepted Answer

The parietal reach region (PRR) is known to be involved in planning reaching movements, including the intention to grab an object. Studies in monkeys have shown that neurons in the PRR fire when the monkey intends to reach out and grasp an object, prior to any actual movement being made. The other options, hippocampus, superior colliculus, and nystagmus parietal radius (NPR), are not typically associated with planning or executing reaching movements.
