Error-related medial frontal theta activity predicts cingulate-related structural connectivity

Michael X Cohen
2011 NeuroImage  
Correlating individual differences in medial frontal theta dynamics with white matter tracts linking these dipole sources to the rest of the brain revealed that subjects with stronger error-related theta  ...  Next, a dipole source of the error-related theta-band activity was localized for each subject, accounting for approximately 80% of the topographical variance.  ...  Whereas error-related theta power at medial frontal sites predicted white matter connectivity between the estimated source (usually in the anterior cingulate) and motor, ventral striatal, and right ventrolateral  ...

Synchronizing theta oscillations with direct-current stimulation strengthens adaptive control in the human brain

Robert M. G. Reinhart, Julia Zhu, Sohee Park, Geoffrey F. Woodman
2015 Proceedings of the National Academy of Sciences of the United States of America  
Here, we provide support for the view that oscillatory activity in the frontal cortex underlies adaptive adjustments in cognitive processing following errors.  ...  To demonstrate that these abnormal oscillations were the origin of the impaired adaptive control in patients with schizophrenia, we applied noninvasive dc electrical stimulation over the medial-frontal  ...  We reasoned that if temporal structured medial-frontal theta activity underlies normal adaptive control, the patients should exhibit abnormal medial-frontal theta provided that they show abnormal posterror  ...

It appears that the strength of event-related EEG activity increases with increased integrity of structural connectivity, while latency drops.  ...  Implications of structural connections within and between brain regions for their functional counterpart are timely points of discussion.  ...  Cohen (2011) suggested that structural networks underlie the generation of medial frontal error-related neural dynamics and the neural activity related to error processing.  ...

The default-mode, ego-functions and free-energy: a neurobiological account of Freudian ideas

2011 PLoS ONE  
Using s-LORETA the sources of this deactivation were localised to medial prefrontal regions, posterior cingulate cortex/precuneus and temporal regions.  ...  Furthermore, these seem to be related to ADHD symptom status, with high ADHD adults failing to significantly deactivate medial prefrontal regions while at the same time showing significant attenuation  ...  For the low ADHD group, as predicted, the deactivations were localised to medial prefrontal regions, including the cingulate gyrus (BA 23, BA 24, BA 32), medial prefrontal gyrus (BA 6) and superior frontal  ...
