Time in Cortical Circuits

J Neurosci. 2015 Oct 14;35(41):13912-6. doi: 10.1523/JNEUROSCI.2654-15.2015.

Abstract

Time is central to cognition. However, the neural basis for time-dependent cognition remains poorly understood. We explore how the temporal features of neural activity in cortical circuits and their capacity for plasticity can contribute to time-dependent cognition over short time scales. This neural activity is linked to cognition that operates in the present or anticipates events or stimuli in the near future. We focus on deliberation and planning in the context of decision making as a cognitive process that integrates information across time. We progress to consider how temporal expectations of the future modulate perception. We propose that understanding the neural basis for how the brain tells time and operates in time will be necessary to develop general models of cognition.

Significance statement: Time is central to cognition. However, the neural basis for time-dependent cognition remains poorly understood.
