The video above shows the change in firing rates of neurons across the entire brain during the average trial of the IBL decision-making task. Each dot represents one of 75,708 good units recorded in the brain-wide map dataset. The size of each dot represents the change in firing rate from the baseline activity. Baseline activity was calculated as the average firing rate during the first 300ms of the trial (the quiescent period). Many neurons have low firing rates and may be invisible, but to ...
