Visually evoked potential (IMAGE) Picower Institute at MIT Caption Data from the paper show a sharp but brief increase in neural activity -- a visually evokied potential -- when a stimulus pattern is shown to a mouse at about 80 milliseconds (bright orange vertical line). Notably when a stimulus is familiar, activity decreases significantly (cooler colors) after that transient increase.
