Using ROI analysis the study demonstrated that in the cocaine abusers, but not in the control subjects, cocaine craving elicited by the videotapes resulted in increased blood flow in the amygdala and anterior cingulate cortex and decreased blood flow in the caudate nucleus and in the globus pallidus, which connects the striatum and the thalamus.
Components of the basal ganglia are the caudate nucleus, putamen and globus pallidus.
Experiments with rats suggest that transplants of tissue from the adrenal medulla to the caudate nucleus in the brain may be able to block such damage.
Compared with controls, the Alzheimer brains showed a marked reduction of CRF concentrations in three regions: about 50 percent reduction in the frontal and temporal cortex, and 70 percent in the caudate nucleus. The report apparently is the first to point out CRF deficiencies in Alzheimer's, but the significance of the findings remains unclear.
