Fig. 5: Emergence of low-dimensional, task-related neuronal signals in mPFC.
From: Population-level coding of avoidance learning in medial prefrontal cortex
a, Mean projections (n = 80 repetitions) of neural data onto the five coding dimensions for trials with and without shuttling during habituation (day 1), task 1 (days 2–4), task 2 (days 5–9) and extinction (days 10–11). b, Absolute variance within each coding dimension. c, Relative VE by the five coding dimensions across the 11-day learning paradigm. Mean over 80 repetitions. d, Avoid versus error decoding accuracy (time-averaged for the 2 s preceding shuttle start) for the decoder that was used to define the avoid 1 dimension (mean and 95% CIs for 80 repetitions). Decoders were trained with data from tasks 1 and 2 and separately evaluated with test data from individual days. The black bar indicates performance that is significantly above chance based on 50% not being included in the CI. e, Same as d, but for the decoder that was used to define the avoid 2 dimension (the avoid 1 dimension was already removed). T1, task 1; T2, task 2.
