New paper by Johannes Algermissen in Cerebral Cortex

Our study titled “Striatal BOLD and Midfrontal Theta Power Express Motivation for Action” is now published online in the Cerebral Cortex journal. In this study, we examined the mechanisms behind the effect of motivational biases on action selection using simultaneous EEG-fMRI during a Go/NoGo learning task. We found that striatal BOLD selection of active Go responses and correlated with theta power around response time. Within trials, theta power ramped in the fashion of an evidence accumulation signal for the value of making a “Go” response, capturing the faster responding to reward cues. Our findings reveal a dual nature of mid-frontal theta power, with early components reflecting the vmPFC contribution to motivational biases, and late components reflecting their striatal translation into behavior.
