Fig. 9: Changes in delay responses: pre-training vs. post-training.
From: Functional role of cell classes in monkey prefrontal cortex after learning a working memory task

A Comparison of firing rate during the first delay period between pre-training passive (light color) and post-training active (dark color) phases for each cell class in the spatial task. B Comparison of Fano factor during the delay period between pre-training and post-training phases for each cell class in the spatial task. C Comparison of coefficient of variation during the delay period between pre-training and post-training phases for each cell class in the spatial task. D Comparison of local variation during the delay period between pre-training and post-training phases for each cell class in the spatial task. E Comparison of firing rate during the delay period between pre-training and post-training phases for each cell class in the feature task. F Comparison of Fano factor during the delay period between pre-training and post-training phases for each cell class in the feature task. G Comparison of coefficient of variation during the delay period between pre-training and post-training phases for each cell class in the feature task. H Comparison of local variation during the delay period between pre-training and post-training phases for each cell class in the feature task. Each box plot shows the median (horizontal line), interquartile range (box), and whiskers extending to 1.5 times the interquartile range. Gray dots represent individual data points for each unit, and larger black dots indicate group means. *, **, and *** indicate p < 0.05, p < 0.01, and p < 0.005, respectively (Mann-Whitney U test).
