| 550210 | Midfrontal alpha oscillations | Striatal BOLD and midfrontal theta power express motivation for action | Parametric regressor: trial-by-trial midfrontal (mean of channels FCz, Cz) alpha oscillations (175 - 325 ms relative to cue onset, 8 - 13 Hz) measured using scalp EEG. This alpha response is significantly higher for correct bias-incongruent actions (Go actions to Avoid cues/ NoGo actions to Win cues) than correct bias-congruent actions (Go actions to Win cues/ NoGo actions to Avoid cues). Motivational Go/NoGo task (Swart et al., 2017; 2018; van Nuland et al., 2020). Note that this Go/NoGo task is equiprobable (percent Go/NoGo trials is 50:50) and thus does NOT elicit strong inhibition-related activation. |
| 563793 | Midfrontal alpha oscillations | Biased credit assignment in motivational learning biases arises through prefrontal influences on striatal learning | Parametric regressor: trial-by-trial frontal (t-weighted mean of channels Cz/ FCz/ Fz) lower alpha band oscillations (0–425 ms relative to outcome onset, 6 - 10 Hz) measured using scalp EEG. This alpha band response is significantly higher when previously, a Go response was performed than when a NoGo response was performed. This regressor is added on top of GLM2 regressors (featuring 8 outcome x response regressors plus standard prediction errors and the difference term to biased prediction errors), yielding GLM3A. Motivational Go/NoGo task (Swart et al., 2017; 2018; van Nuland et al., 2020). |
