One PPC region, the lateral intraparietal cortex, appears to be particularly important for eye movements, whereas a nearby region, the medial intraparietal cortex (MIP; also known as the partial reach region, PRR), plays a larger role in reaching movements.

What is the function of lateral intraparietal cortex?

The lateral intraparietal cortex (area LIP) is found in the intraparietal sulcus of the brain. This area is most likely involved in eye movement, as electrical stimulation evokes saccades (quick movements) of the eyes.

What does the lateral intraparietal area do?

In this review, we will describe the way the lateral intraparietal area (LIP) of posterior parietal cortex acts as a priority map to help guide the allocation of covert attention and eye movements (overt attention).
