Prefrontal cortex and impulsive decision making
S Kim, D Lee - Biological psychiatry, 2011 - Elsevier
Impulsivity refers to a set of heterogeneous behaviors that are tuned suboptimally along
certain temporal dimensions. Impulsive intertemporal choice refers to the tendency to forego …

A proactive mechanism for selective suppression of response tendencies
While most research on stopping action examines how an initiated response is stopped
when a signal occurs (ie, reactively), everyday life also calls for a mechanism to prepare to …

Stimulation at dorsal and ventral electrode contacts targeted at the subthalamic nucleus has different effects on motor and emotion functions in Parkinson's disease
I Greenhouse, S Gould, M Houser, G Hicks, J Gross… - Neuropsychologia, 2011 - Elsevier
Motor and emotion processing depend on different fronto-basal ganglia circuits. Distinct sub-
regions of the subthalamic nucleus (STN) may modulate these circuits. We evaluated …

Response inhibition and response monitoring in a saccadic countermanding task in schizophrenia
BACKGROUND:: Cognitive control deficits are pervasive in individuals with schizophrenia
(SZ) and are reliable predictors of functional outcome, but the specificity of these deficits and …

Individual differences in heart rate variability predict the degree of slowing during response inhibition and initiation in the presence of emotional stimuli
Response inhibition is a hallmark of executive control and crucial to support flexible
behavior in a constantly changing environment. Recently, it has been shown that response …
