This chapter examines the role of neural activity in the lateral intraparietal area (LIP) on intention to make saccadic eye movement and on attention in the lateral intraparietal area in monkeys. It describes the results of experiments which reveal that LIP predicts a monkey's attention on a millisecond-by-millisecond basis and is independent from saccade planning. It shows that the activity of LIP predicts the goal and latency of saccades in a free-viewing visual search task and suggests that it provides a salience map which is interpreted by the oculomotor system as a saccade goal when a saccade is appropriate.

Keywords:   intraparietal area, eye movement, attention, monkeys, saccade planning, search task, oculomotor system, neural activity
