Abstract

In monkeys performing a visual spatial attention task, stimulation of neurons in the lateral geniculate nucleus and recording of shock-evoked responses from monosynaptically connected primary-visual-cortex neurons shows that attention enhances neuronal communication by increasing the efficacy of presynaptic input, increasing synchronous responses, and by decreasing redundant signals.
