In fact, most of the studies limited their analysis to the caudate nucleus
; thalamus; amygdala; and orbital, dorsolateral frontal, and anterior cingulate cortices.
In addition to its role in anticipating reward, the caudate nucleus
is involved in helping people learn classifications.
Caption: Figure 1: (a) DaTSCAN detected a slight decrease in tracer uptake in the left caudate nucleus
, as well as reduced uptake in the putamina (more marked in the left).
The caudate nucleus
is implicated in reinforcement of goal-directed actions  hinting at the possibility that caudate's role in facial mimicry could be to mitigate the rewarding outcome of accurate emotion recognition.
CAU: caudate nucleus
; GPe: external globus pallidus; GPi: internal globus pallidus; L: left; PUT: putamen; R: right.
Cranio-cerebral CT images at admission (left) and 24 hours (right), where the hypodense area in the left basal nuclei and head of the caudate nucleus
can be seen
Mapping of segmented structures: Once the image registration process was completed, nine already segmented mid-brain structures of reference image ie left ventricle, right ventricle, 3rd ventricle, left putamen, right putamen, left caudate nucleus
, right caudate nucleus
, anterior commissure and posterior commissure were mapped (Ali and Khan, 2011) from the reference image to target images by applying the final transformation achieved, as a result of registration process.
An initial MR of the patient's brain from an outside facility showed an area of abnormal restricted diffusion in the left caudate nucleus
on diffuse weighted imaging (DWI) with corresponding abnormality on apparent diffusion coefficient (ADC) map respectively, consistent with a recent vascular insult or inflammatory process.
In addition, 24 images of the type III aspiny neurons from the human neostriatum , 15 neuronal images from the putamen (Figure 1(c)), and 9 neuronal images from the caudate nucleus
(Figure 1(d)), were analyzed with the standard and the modified BC method.
Deficits in executive function can be attributed to the reduced activity in the caudate nucleus
, even in people without dementia .
After being corrected with FDR simulations (p = 0.001, [alpha] = 0.05, cluster size = 326), we found that FA increased in the bilateral head of the caudate nucleus
(HCN), lenticular nucleus (LN), ventral thalamus, substantia nigra (SN), red nucleus (RN), right dentate nucleus (DN), and decreased in the mediodorsal thalamus and extensive white matter (Figure 1(a)).
Effects of Maternal Deprivation on the Expression of NADPH Subunits in the Cortex, Hippocampus, Thalamus, and Caudate Nucleus
. Quantitative Western blot analysis have revealed increased expression of [gp91.sup.phox] both in the cortex (p = 0.0046) and in the hippocampus (p = 0.0003) and decreased expression in thalamus (p = 0.0035) and caudate nuclei (p = 0.0494) of MD group compared to control group (Figures 1(a) and 1(b)).
