The superior colliculus is a laminated midbrain structure that acts as one of the centers
organizing gaze movements. This review will concentrate on sensory and motor inputs to the …

In the 16 years since we last summarized the behavior of the premotor elements that control
saccades, research has revealed shortcomings in previous formulations of the control …

Life on earth has evolved under the influence of regularly recurring changes in the
environment, such as the 24 h light/dark cycle. Consequently, organisms have developed …

Saccades are rapid eye movements that redirect the fovea from one object to another. A
great deal has been learned about the anatomy and physiology of saccades, making them …

Many neurons within prefrontal cortex exhibit a tonic discharge between visual stimulation
and motor response. This delay activity may contribute to movement, memory, and vision …

The role of the primate superior colliculus (SC) in orienting head movements was studied by
recording electromyographic (EMG) activity from multiple neck muscles following electrical …

The ability of primates to make rapid and accurate saccadic eye movements for exploring
the natural world is based on a neuronal system in the brain that has been studied …

There is general agreement that saccades are guided to their targets by means of a motor
error signal, which is produced by a local feedback circuit that calculates the difference …

The organization of the motoneuron subgroups in the brainstem controlling each extraocular
eye muscle is highly stable through the vertebrate species. The subgroups are …

Objective This review details the anatomy and interactions of the postural and
somatosensory reflexes. We attempt to identify the important role the nervous system plays …
