Figure 4

ROC areas for M.R. (a) and C.S. (c), comparing classification performance when taking into account all implanted areas versus after dropping in turn one area. Red bars refer to the S-sequence, blue bars to the C-sequence (b and d). Significant differences between keeping all the contacts and dropping in turn couples of electrodes were observed for the S-sequence only for the string including the hippocampus and right frontal caudate contact for C.S. By contrast for the C-sequence, a significant drop in the classification accuracy was evident for many areas. Importantly single-trial classification remains always lower in the C-sequence than in the S-sequence. Abbreviations: LA = left amygdala; RA = right amygdala; LAH = left anterior hippocampus; LPH = left posterior hippocampus; RAH = right anterior hippocampus; RPH = right posterior hippocampus; LFO = left fronto-orbital area; RFO = right fronto-orbital area; LO = left occipital; RO = right occipital; RFC = right frontal-caudate. Standard errors are shown.
