Activation of a Visual Cortical Column by a Directionally Selective Thalamocortical Neuron (Cell Reports)

In awake rabbits, Bereshpolova et al. measure the synaptic impact generated in V1 by individual LGN directionally selective neurons. These neurons make fast and strong synaptic connections in layers 4 and 6, generating postsynaptic effects similar to those made by LGN concentric neurons, the main thalamic drivers of V1.
