Behavioral task and results.
(a) Trial structure. Each trial included a quiz task, a rest or mood assessment period, and a choice task followed by a challenge. In the quiz task, subjects answered a general knowledge question …

Variations in mood rating (black dots) and theoretical mood level (TML, yellow line) across all trials of an experimental session for a single subject, superimposed with episodes of high (blue) and low (red) positive feedback rates.
The rate of correct feedback was manipulated by asking more or less difficult questions in the quiz task. Note that between episodes of high and low positive feedback rates (trials in white), the …

Intracerebral activity underpinning mood fluctuations.
(a) Anatomical location of the ventromedial prefrontal cortex (vmPFC) (blue) and dorsal anterior insula (daIns) (red) in the standard Montreal Neurological Institute template brain, along with all …

Anatomical location of all recording sites (n=3188 sites acquired from 30 epileptic patients) in the standard Montreal Neurological Institute template brain.
Colored brain regions represent the ventromedial prefrontal cortex (vmPFC) (blue) and the dorsal anterior insula (daIns) (red), and colored dots recording sites located in these region. The whole …

Impact of intracerebral activity on decision making.
(a) Intracerebral electroencephalographic (iEEG) activity predicting choice. Plots show the time course of estimates obtained from the regression of choice residuals against broadband gamma activity …

Schematic summary.
A higher baseline broadband gamma activity (BGA) in the ventromedial prefrontal cortex (vmPFC) was both predicted by good mood and associated with higher accept rates in the subsequent choice task, …
