Abstract
Parvalbumin interneurons (PV-INs) are the largest subpopulation of GABAergic neurons. Recent evidence suggests transcallosal projections of PV-INs within primary motor, visual and auditory cortices. Whether transcallosal PV-INs feature prominently, and the extent to which their local influence affects global excitatory activity is unknown. We created a novel imaging system and mouse line for all-optical neuronal probing and readout to map local and global interactions between excitatory neurons and PV-INs over the cortex in awake mice. PV-INs extend inhibitory influences spanning several mm over the cortex and into more distant, ipsilateral regions. Further, we show region-specific interhemispheric inhibitory influences of PV-INs.
