Gaze and smooth pursuit signals interact in parietal area 7m of the behaving monkey.

Posterior parietal cortex is a region specialized for multimodal integration and coordinate transformations which converts sensory input to motor output. Eye position signals are crucial for such transformations, because they are needed to the inner reconstruction of a stable image of the outside world in spite of eye movements. Area 7m is a parietal area anatomically connected with oculomotor structures such as frontal eye field and superior colliculus.

Neuronal responses to optic flow in the monkey parietal area PEc.

Area PEc, a high order association area, is located in the dorsocaudal portion of the superior parietal cortex. PEc neurons encode visual motion signals, especially the direction of stimulus motion. The present study tested if PEc neurons also process visual correlates of self-motion.
