Through a largescale, international data sharing and dataanalysissharing effort, we were able to actually successfully identify genetic effects on the hippocampus, putamen and other brain regions that no one had ever successfully identified genetics effects on before," said Jessica Turner, associate professor of psychology and neuroscience at Georgia State University.
The second passage inocula were obtained from Tg mice challenged at first passage with BH from frontal cortex and putamen of 1 case patient with VPSPr-129VV and 1 with VPSPr-129MM.
They include the hypothalamus; the striatal region, which includes the putamen and caudate and is in charge of motivation and reward; the limbic region, where emotion and memory reside; and the cortical region, which includes the prefrontal cortex, insula, and anterior cingulate cortex and handles the integration and processing of the brain.
Moderate injury tends to cause T1 hyperintensity of the anterior putamen, and the posteromedial thalamus, with usual loss of the normal T1 hyperintense signal in the posterior limb of the internal capsule.
The lenticulostriate arteries are end branches of the middle cerebral arteries which supply the caudate, putamen and the internal capsule.
Specifically, males on average had larger volumes and higher tissue densities in the left amygdala, hippocampus, insular cortex, putamen; higher densities in the right VI lobe of the cerebellum and in the left claustrum; and larger volumes in the bilateral anterior parahippocampal gyri, posterior cingulate gyri, precuneus, temporal poles, and cerebellum, areas in the left posterior and anterior cingulate gyri, and in the right amygdala, hippocampus, and putamen.
A true pulvinar sign (consistent with variants of CJD) must be considered only if the high signal in the pulvinar is greater than the hyperintensity in the caudate and putamen nucleus.
1) When patients have predominant hepatic involvement, T1 hyperintensity is noted in the globus pallidus, putamen and mesencephalon.

We selected the AAL ROIs on the left and right caudate nucleus (CN) and left and right putamen (see Figure 2).
GALNT9 expression was initially thought to be exclusive to the brain, with mRNA concentrations being more abundant in the cerebellum than in the cerebral cortex, frontal lobe, temporal lobe, and putamen (21).
