Induction of LTP in the striatum
begins with activation of certain postsynaptic receptors for the neurotransmitter glutamate (i.
Major finding: Regardless of outcome when challenged with a risk/reward task, the ventral striatum
in the brains of cannabis-smoking youths did not activate.
(Stereotaxic Atlas of the Rat Brain; George and Charles, 2005) and the right limb soleus muscle fibers were excised from eight rats.
Moreover we found that another brain region, that is also part of the striatum
that is active when people see sexual stimuli, shows less activation the more pornography participants consumed," she added.
The magnitude of the deactivation of brain activity in the right thalamus and striatum
induced by the HFD was positively correlated with the magnitude of the decrease in percent sugar preference (r=0.
GABAergic neurons, located in the striatum
, are the cell type most susceptible to degeneration in HD.
The levels of Dopamine (DA) and Homovanillic acid (HVA) in striatum
were determined by Ultra-performance liquid chromatography combined with time-of-flight mass spectrometry (UPLC-ToF-MS).
People prepared to work hard for rewards had more of the nerve signalling chemical dopamine in two brain regions called the striatum
and ventromedial prefrontal cortex.
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.
PBT434 preserves critical interneuronal connections between the substantia nigra and the striatum
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.
In a later study, Kalivas and Volkow (2005) (8) proposed that activation of DRD2 in the prefrontal cortex modulates excitatory neurons which in turn project to the striatum
and intervene in motivation and action.
Low D2 receptor availability in the striatum
of obese subjects was associated with decreased activation in the prefrontal cortex involved in inhibitory control--a pattern similar to that found in alcoholics.
Injury to nerve cells in the striatum
of the brain is likely to contribute to the motor deficits seen in cerebral palsy (Volpe, 2001a).
Extract the left and right striatum
from the left and right hemisphere images using a deformable model.
