Analysis of stimulus value. Top, Heat maps of significant p values associated with stimulus value in (A) NC and (B) SCC sessions. Both sessions show significant stimulus value activity arising from ∼400–450 ms after stimulus onset (green boxes). Middle, Topographic scalp distribution (left) and average waveforms (right) for (C) 400–500 ms period in NC, and (D) 450–650 ms period in SCC. For all average waveforms, the highlighted gray window indicates the window of significant activity, which was also specified as the time window of interest for source reconstruction. Red, Strong No; orange, No; cyan, Yes; green, Strong Yes. E, Source reconstruction results for NC (yellow) and SCC (cyan, 450–650 ms) sessions displayed on a glass brain MIP. F, Sources overlaid on a representative brain image show localization to regions including vmPFC (circled). Inset, Spherical masks based on peak coordinates from three fMRI studies [blue, Plassmann et al. (2007); magenta, Hare et al. (2009); cyan, Litt et al. (2010)], 6 mm radius.
