Variability comparison of neural population dynamics of chewing gapes at different stages in two monkeys. (A) Selective two consecutive chewing gapes at Stage 1, Stage 2 and Stage 3 within one almond(shell) trial (left: Monkey O, Dataset 1; right: Monkey A, Dataset 2). Panels (B)–(D): top: Monkey O, Dataset 1; bottom: Monkey A, Dataset 2. (B) Dissimilarity (mean divergence measure) of six gapes in panel (A), characterized by a 6 × 6 matrix. Light color represents a high similarity. (C) Dissimilarity (mean divergence measure) percentile of total n gapes in a full single feeding trial, characterized by an n × n matrix. Dashed lines indicate the boundary between the three chewing stages. (D) Comparison of within and inter-stage group statistics of variability in population response during chewing across all feeding trials. In both cases, the intra-stage (Stage 2 versus Stage 2) had smallest divergence statistics, whereas the inter-stage (State 3 versus Stage 2) had the largest divergence statistics. These two groups were significantly different (p < 0.01, two-sample KS test; p < 0.01, rank-sum test).
