The neural basis for combinatorial coding in a cortical population response

The modern study of neural coding began with the discovery that neural responses to sensory stimuli are composed of discrete events: either a cell generates an action potential or it remains silent (Adrian, 1926). If we average, either over long periods of time or over many presentations of the same ...
