Summary: Changes in arousal modulate the activity of mouse sensory cortex. but studies in different mice and different sensory areas disagree on whether this modulation enhances or suppresses activity. We measured this modulation simultaneously in multiple cortical areas by imaging mice expressing voltage-sensitive fluorescent proteins (VSFP). VSFP imaging estimates local membrane pot... https://www.chiggate.com/color-charm-050-cooling-violet-supply/
