Frontal-midline theta promotes context-dependent risk aversion in social anxiety Open
Social anxiety is reliably characterized by biases toward avoidance and aversive learning. Here we examined the neurocomputational processes underlying these biases and examined whether these biases persist across different social contexts…

The Reward Positivity Signals a Goal Prediction Error Open
The Reward Positivity (RewP) is an electroencephalographic feature that emerges following performance feedback and is commonly understood to index both positive and negative reward prediction error (RPE) signals. Contrary to this dominant …

The Reward Positivity: A Goal Prediction Error Open
The Reward Positivity (RewP) is an electroencephalographic feature that emerges following reward receipt and is sensitive to positive prediction errors and other experiences of hedonic value. Here we address two unresolved issues regarding…

Theta-frequency subthalamic nucleus stimulation increases decision threshold Open
These findings extend our knowledge of how the STN controls decision thresholds. Future work will study the STN's role in motor and cognitive control and how stimulating this region may modulate cognition in PD.

Basal ganglia components have distinct computational roles in decision-making dynamics under conflict and uncertainty Open
The basal ganglia (BG) play a key role in decision-making, preventing impulsive actions in some contexts while facilitating fast adaptations in others. The specific contributions of different BG structures to this nuanced behavior remain u…

Hypoactivation of ventromedial frontal cortex in major depressive disorder: an MEG study of the Reward Positivity Open
Background The Reward Positivity (RewP) is sensitive and specific electrophysiological marker of reward receipt. These characteristics make it a compelling candidate marker of dysfunctional reward processing in major depressive disorder. W…

Slowing of Parameterized Resting-State Electroencephalography After Mild Traumatic Brain Injury Open
Reported changes in electroencephalography (EEG)-derived spectral power after mild traumatic brain injury (mTBI) remains inconsistent across existing literature. However, this may be a result of previous analyses depending solely on observ…

Neural response to monetary incentives in acquired adolescent depression after mild traumatic brain injury: Stage 2 Registered Report Open
Depression is a common consequence of traumatic brain injury. Separately, spontaneous depression—arising without brain injury—has been linked to abnormal responses in motivational neural circuitry to the anticipation or receipt of rewards.…

Test-retest reliability of spectral parameterization by 1/<i>f</i> characterization using <i>SpecParam</i> Open
SpecParam (formally known as FOOOF) allows for the refined measurements of electroencephalography periodic and aperiodic activity, and potentially provides a non-invasive measurement of excitation: inhibition balance. However, little is kn…

Effects of anodal tDCS on electroencephalography correlates of cognitive control in mild-to-moderate traumatic brain injury Open
BACKGROUND: Transcranial direct current stimulation (tDCS) may provide a potential therapy for cognitive deficits caused by traumatic brain injury (TBI), yet its efficacy and mechanisms of action are still uncertain. OBJECTIVE: We hypothes…
