It is unclear why cue-induced craving fails to activate the thalamus, because both drug-induced and cue-induced craving are associated with activity changes in the anterior cingulate gyrus, caudate nucleus, amygdala, and orbital cortices.
The researchers found that activation in the caudate nucleus changed in parallel with this reevaluation.
T1-weighted magnetic resonance imaging (MRI T1)--axial (hyperintensity of right caudate nucleus and putamen).
In our case, the DaTSCAN revealed abnormal tracer uptake in the left caudate nucleus and reduced tracer uptake in the putamina (especially in the left putamen); these findings were coherent with the patient's symptoms of right-sided bradykinesia.
Neuroimaging research has also elucidated areas of the brain that are highly active during facial mimicry, particularly in areas of the basal ganglia (e.g., caudate nucleus) and of the mirror neuron system (e.g., inferior frontal operculum) [25, 26].
The basal ganglia are a group of subcortical gray nuclei, which include the dorsal striatum [i.e., caudate nucleus (CAU) and putamen (PUT)], ventral striatum [including the nucleus accumbens (NA)], globus pallidus (GP), substantia nigra (SN), and subthalamic nucleus (STN), and have complex anatomical and functional projections in the brain (1,2).
Within the first 24 hours, the outcome was favorable, the native craniocerebral CT scan, demonstrating a hypodense area suggestive of a recent ischemic stroke at the left basal nucleus and partially at the head of the caudate nucleus (Figure 2).
Using this scheme, the aim was to segment nine mid-brain structures including left ventricle, right ventricle, third ventricle, anterior commissure, posterior commissure, left putamen, right putamen, left caudate nucleus and right caudate nucleus.
Recurrent migraine attacks lead to sensitization of the pain receptor of the trigeminal nerve on meninx, resulting in central sensitization of the caudate nucleus of the trigeminal nerve.
"The patient had brain MRI, which showed a general brain atrophy (the wasting away or decrease in size of an organ or tissue in the body) and severe atrophic changes in the basal ganglia especially the head of the caudate nucleus and that's when the Huntington disease was suspected and the genetic testing was ordered," said Dr Al Madani.
MR (Figure 1A) axial FLAIR image demonstrates abnormal signal intensity within the left caudate nucleus. (Figure 1B) axial T2WI demonstrates dilatation of perivascular spaces at the base of the brain.
As noted above, a total of 552 neurons (301 cells of the putamen and 251 cells of the caudate nucleus) were observed from both cerebral hemispheres [10].
