RSUs receive both less numerous and weaker thalamocortical connections than do FSUs. A, Summary of the proportions of connected pairs observed for each anatomical category studied (see Results). Error bars indicate SEs of the proportion. B, Standard box plots of the efficacy of pairs of thalamic and barrel FSUs and RSUs found to be connected and not connected (N.C.). Boxes indicate 25–75 percentile ranges of the distributions; lines through boxes indicate medians; vertical lines indicate tails of distributions; isolated horizontal linesindicates outliers.
