摘要：
The lateral geniculate nucleus of the rat was injected with the anterograde tracer Phaseolus vulgaris leucoagglutinin (PHA-L) to see if geniculo-cortical axons terminate on vasoactive intestinal polypeptide immunoreactive (VIP-LR) neurons of the primary visual cortex. PHA-L-labelled boutons attached to VIP-LR perikarya and dendrites were identified as presynaptic parts of asymmetrical synapses. This geniculo-cortical projection to VIP-IR cells in the visual cortex and comparable findings in the somatosensory cortex suggest that sensory input from specific thalamic nuclei may influence local circuit inhibition and the metabolic state within the cortical domain via VIP-IR neurons.
