Research Abstract

Response properties of thalamic neurons to whisker stimulation in rats. Furthermore, in cortical layer 4 arborization of axons derived from the recorded neuron was reconstructed. By analyzing the correlation between the response properties and the axonal arborization in each neuron, we revealed that thalamocortical input consists of two overlapping angular tuning maps.
