563792 Midfrontal beta 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) beta oscillations (300–1,250 ms relative to outcome onset, 13 - 30 Hz) measured using scalp EEG. This beta response is significantly higher for positive outcomes (rewards/ no punishments) than negative outcomes (no rewards/ punishments). 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 GLM3C. Motivational Go/NoGo task (Swart et al., 2017; 2018; van Nuland et al., 2020).
563791 Frontal theta/delta oscillations Biased credit assignment in motivational learning biases arises through prefrontal influences on striatal learning Parametric regressor: trial-by-trial frontal (wide ROI; t-weighted mean of channels AF3/ AF4/ AF7/ AF8/ F1/ F2/ F3/ F4/ F5/ F6/ F7/ F8/ FC1/ FC2/ FC3/ FC4/ FC5/ FC6/ FCz/ Fp1/ Fp2/ Fpz/ Fz) theta/delta oscillations (225–475 ms relative to outcome onset, 1 - 8 Hz) measured using scalp EEG. This theta response is significantly higher for negative outcomes (no rewards/ punishments) than positive outcomes (rewards/ no punishments). 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 GLM3B. Motivational Go/NoGo task (Swart et al., 2017; 2018; van Nuland et al., 2020).
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.
550211 Midfrontal theta oscillations Striatal BOLD and midfrontal theta power express motivation for action Parametric regressor: trial-by-trial midfrontal (mean of channels FCz, Cz) theta oscillations (-250 - 250 ms relative to response, 4 - 8 Hz) measured using scalp EEG. This theta response is significantly higher for (correct) Go actions than (correct) NoGo actions. 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).
