Learning capacity depends on a dynamic interplay between the brain’s ability to change the strength of its synapses and the history of activity at those synapses.
Local disinhibition provides a biologically plausible mechanism for flexible top-down control of network states that integrates normalized value coding, winner-take-all choice, and persistent activity in a single circuit of decision-making.
