Lack of centripetal connection between the lateral olfactory tract and the caudate nucleus. Evoked potential study in the rat.

abstract：PURPOSE:To examine the accuracy and latency of reflexive saccades to vibratory stimulation of the fingertips made by normal human subjects and to compare the findings to those of visually guided saccades. METHODS:Eye movements were recorded using infrared oculography. Stimuli were presented via an array of audiometric...
