Layers of the monkey visual cortex are selectively modulated during electrical stimulation

Biophysics of electrical stimulation in V1 layers.
Distributions of electrical voltage and electric field across cortical layers in A) monkey 1 and B) monkey 2. The electrical voltage and electric field values were normalized to their maximum values. The electric field was calculated by taking the gradient of the voltage along the direction of the laminar probe. For both capuchin monkeys, the electric field began to increase from layer 1, reaching the maximum in layers 2/3, and then decreased in deeper layers.
