Index of population-level information about a memory cue when a classifier is cross-trained and tested on different time bins. Early in the trial, during the presentation of the memory cue, there is a highly selective pattern as evidenced by relatively strong on-diagonal classification accuracy but poor off-diagonal classification accuracy. However, after several hundred msec, the pattern stabilizes into a more generalizable code (as indexed by more off-diagonal information). This dynamic transition in the multivariate code over the course of a trial runs counter to the traditional notion that sustained and stable spiking activity over the entire course of the delay period is the signature pattern of a code for STM.
