- claim_text
Mouse visual, somatosensory and motor cortex all show the paradoxical suppression of parvalbumin-interneuron firing in response to optogenetic PV excitation predicted by inhibition-stabilized network theory, indicating that strong recurrent excitation balanced by feedback inhibition is a common operating regime of mouse neocortex.

Simple two-population ISN models describe the data well and let us quantify coupling strength. We find ISN effects without sensory stimulation and even during light anesthesia. Average paradoxical effects result only with transgenic, not viral, opsin expression in parvalbumin (PV)-positive neurons; theory and expression data show this is consistent with ISN operation.
