Macaque V1 representations in natural and reduced visual contexts: spatial and temporal properties and influence of saccadic eye movements.

abstract：:1. We study the propagation and dynamics of spindle waves in thalamic slices by developing and analyzing a model of reciprocally coupled populations of excitatory thalamocortical (TC) neurons and inhibitory thalamic reticular (RE) neurons. 2. Each TC neuron has three intrinsic ionic currents: a low-threshold T-type Ca...
