First, we find that stimulation of excitatory cells leads to a salt-and-pepper pattern of local suppression, consistent with the pattern of excited and suppressed cells produced when animals see a strong visual stimulus.

claim_text
Optogenetic stimulation of excitatory cells in mouse V1 produces a salt-and-pepper pattern of distributed suppression among non-stimulated neurons, with ~44% of neurons suppressed; this is quantitatively reproduced by a strongly coupled recurrent E-I network model.
