Summary
Summary Perception does not depend on environment alone, but also on brain state. Work from our lab and others show that visual responses to certain features are selectively gated depending on an animal's arousal state. What are the circuit and synaptic bases for these state-dependent shifts in visual sensitivity? State- dependent modulation of sensory responses has been well-described in visual cortex. Studies have also identified behavioral modulation of responses neurons in the dorsolateral geniculate nucleus of the visual thalamus (dLGN) of mice and primates. Remarkably, in vitro studies f
