Long-term cocaine consumption is associated with brain structural and functional changes.
While the animal literature on cocaine use and dependence has traditionally focused on the …

Recent research has examined anxiety and hyperactivity in the amygdala and the anterior
hippocampus while processing aversive stimuli. In order to determine whether these …

The topic of investigating how mindfulness meditation training can have antidepressant effects
via plastic changes in both resting state and meditation state brain activity is important in …

Using optimized voxel‐based morphometry, we studied the relationship between gray matter
volume in brain areas associated with reward and scores on a behavioral activation system …

Increasing neuroimaging evidence suggests that mindfulness meditation expertise is related
to different functional and structural configurations of the default mode network (DMN), the …

The Behavioral Inhibition System (BIS) is described in Gray’s Reinforcement Sensitivity
Theory as a hypothetical construct that mediates anxiety in animals and humans. The …

We used fMRI to study brain activity associated with the performance of a pre-learned
sequence of complex movements of the hand-made unimanually in a group of 13 Parkinson's …

The Reinforcement Sensitivity Theory proposes that a neurobiological system, the Behavioral
Activation System, defines individual differences on the subject’s sensitivity and reactivity …

Dysregulation in cognitive control networks may mediate core characteristics of drug
addiction. Cocaine dependence has been particularly associated with low activation in the …

Pre‐clinical and clinical studies in cocaine addiction highlight alterations in the striatal
dopaminergic reward system that subserve maintenance of cocaine use. Using an instrumental …
