Notes:
Summary Transmission through the lateral geniculate nucleus (LGN) undergoes large, sudden changes, as does excitability of striate cortex, in unanesthetized macaques and squirrel monkeys. Tactile or auditory stimuli, or brief stimulation of the mesencephalic reticular formation has a pronounced facilitatory effect if the monkey is moderately inattentive. However, when the monkey is fully alert, the mesencephalic stimulation may produce no enhancement. During slow-wave sleep, transmission through LGN is greatly curtailed, but excitability of striate cortex is dramatically augmented. Anesthesia, on the other hand, severely depresses both LGN and striate cortex.
