Population-wide distributions of neural activity during perceptual decision-making

► We review population-wide distributions of neural activity across cortex. ► We mostly focus on data from animals involved in perceptual decision-making tasks. ► We study spontaneous, sensory, delay, and motor neural activity during these tasks. ► Distributions of firing rates are consistently long-tailed, across all cortex. ► We also review distributions of other features of activity: tuning, dynamics, etc.
