This ability is a cognitive regulation function that fMRI studies in cigarette smokers show depends upon functional interaction between the dorsolateral prefrontal cortex and the ventral striatum
(Kober et al.
Some evidence also reveals that amphetamine-induced increases in cortisol are associated with both dopamine binding in the ventral striatum
and ratings of amphetamine-induced euphoria.
The age-related findings in individuals with compulsive sexual behaviours suggest that the ventral striatum
may be important in developmental aspects of compulsive sexual behaviours in a similar fashion as it is in drug addictions, although direct testing of this possibility is needed.
As the dorsal (caudate nucleus and putamen) and ventral striatum
(including the nucleus accumbens) constituted primary regions-of-interest (ROI), we performed an ROI analysis on BOLD signal in these areas, using the Marsbar toolbox (Brett et al.
LIMBIC SYSTEM (including the VENTRAL STRIATUM
, AMYGDALA, and HIPPOCAMPUS): feeling pleasure; emotions; learning
The scientists found that when the women were able to hold their boyfriends, they showed increased activity in the reward-related regions of the brain, including the ventral striatum
, a brain region that responds to simple rewards, like chocolate, sex, and money.
Researchers found, for example, that the neural activity in the reward-related regions of the brain known as the ventral striatum
and septal area, was especially noticeable in people offering support and care for a loved one experiencing pain.
In scans performed before the medication regimen, smoking cues activated brain areas involved in drug-motivation, such as the ventral striatum
and medial orbitofrontal cortex, and also elicited reports of craving.
Regions of interest (ROI) with fixed sizes were drawn bilaterally over the striatum, ventral striatum
and dorsal striatum.
When the youngsters (10 to 13-years-olds) were scanned to measure blood flow through their brains, while looking at faces showing a range of emotions, scientists found increased activity in a tiny structure, the ventral striatum
, deep in the brain.
This found that disgust is mostly processed in the anterior insula (AI), (19) which will be described below, happiness is mostly processed in the ventral striatum
, anger is mostly processed in the supplementary motor cortex, and sadness is processed in a number of regions, including the hypothalamus.
In this study, we aim to overcome this limitation and develop an algorithm capable of separating the striatum into four structures (caudate, putamen, ventral striatum
, and white matter) .
