STUDIO DEGLI ADDOTTI CATECOLAMMINE-PROTEINE IN SOSTANZA NERA E NEL PUTAMEN UMANI
… fractions from human substantia nigra and putamen were extracted and analysed. The extracted proteins were incubated with a amino-phenyl boronate resin that selectively binds the cis-diol group of dopamine, a reaction that is reversible at acidic pH. By using this system, dopaminated …

Signaltransduktion im Gehirn SIV-infizierter Rhesusaffen
… Nucleus accumbens, Corpus amygdaloideum und Putamen erhoben. Nucleus accumbens und Corpus amygdaloideum sind Teile des limbischen Systems, die auch in der Pathophysiologie psychiatrischer Störungen und Suchterkrankungen eine Rolle spielen. Das Putamen ist Teil des Corpus striatum, welches …

Studies into Amphetamine-Induced Unconditioned Behaviour in the Rat.
… between the output of the mesolimbic and caudate-putamen, and would predict that stereotyped locomotion represents a 'blending' of mesolimbic and caudate-putamen behavioural output. An experiment was conducted to test the Lyon-Robbins hypothesis using contrast-based image analysis to determine the …

Assessment of Immune System Involvement in Tourette Syndrome
… thalamus, globus pallidus interior, exterior and putamen. Thirty- two children (14 TS, 7 family control, and 11 non-family control) and thirty-nine adults (11 TS, 14 family control, and 14 non-family control) were studied. Immunofluorescent studies were performed on basal ganglia tissue using …

Effects of Δ9-Tetrahydrocannabinol on Neural Reward Anticipation Among Young Adult Cannabis Users
… the nucleus accumbens (NAcc), caudate, and putamen. Multiple linear regressions examined the relationship between problematic cannabis use and reward anticipation under the PBO condition (Aim 1). Repeated-measures analyses of covariance (RM-ANCOVAs) tested main and interactive effects of …

AUTORADIOGRAPHIC STUDIES OF THE REGULATION OF THE SUBTYPES OF THE ß ADRENERGIC RECEPTOR
… of ß-1 adrenergic receptors in the caudate-putamen increased after this treatment. The density of ß-1 receptors did not change in the caudate-putamen following the nonselective lesion. A selective lesion of the dopaminergic input to the caudate-putamen resulted in a decrease in the density …

High-Definition Fiber Tracking Study of the Executive Control Network in Blast-Related Traumatic Brain Injury
… dorsolateral prefrontal cortex (DLFPC) and the putamen, caudate, and thalamus. Groups had similar demographic characteristics, and medical histories. Relative to the comparison group, moderate to strong effects indicated that bTBI was associated with: elevated quantitative anisotropy (QA) and …

Preliminary evidence that prenatal maternal choline supplementation protects the white matter microstructure of infants born to heavy-drinking women
… connections: between the right caudate and right putamen, and right putamen and right pallidum (|β|'s > 0.40; p's < 0.05). Finally, better visual recognition memory on the FTII was associated with lower RD (β (ε) = -0.62 (0.27); p = 0.038) in the connection between the left and right thalami, and …

Are maternal symptoms of depression/PTSD and Child Genetic risk scores for depression/PTSD associated with childhood subcortical brain volumes?
… volumes, and smaller right thalamus, bilateral putamen and total pallidum volumes. Model GxE was associated with larger bilateral caudate volume. For PTSD, model G was associated with larger total and right putamen and right pallidum volume, and with smaller left putamen and left hippocampus …

The impact of maternal HIV infection on uninfected neonate brain structure
… mean caudate volumes bilaterally and left mean putamen volumes relative to HUU neonates. Further analysis revealed the observed differences in basal nuclei volumes were related to duration of ART in utero. Infants exposed to ART throughout pregnancy had similar caudate and putamen volumes …

Effetto dell’esposizione cronica volontaria di eroina e WIN55,212-2 sull’espressione di micro RNA nelle aree cerebrali coinvolte nella dipendenza da sostanze d’abuso
… 125 miRNAs dysregulated in the caudate putamen: 105 upregulated and 20 downregulated and 51 miRNAs dysregulated in the prefrontal cortex, 39 upregulated and 12 downregulated. Following WIN55,212-2 SA we observed that 95 miRNAs were differentially expressed in NAc shell: 40 upregulated …

Magnetresonanztomographie-basierte Volumetrie bei hereditären spinozerebellären Ataxien
… der zerebellären Hemisphären, des Vermis, des Putamens und des Nucleus caudatus. Bei SCA6 hingegen konnten atrophische Veränderungen nur für das Zerebellum und den Pons nachgewiesen werden. Für den zerebralen Kortex konnte keine wesentliche Atrophie beobachtet werden. Mit Hilfe der …

Modelling the Neuropsychopharmacology of Obsessive-Compulsive Disorder in the Common Marmoset (Callithrix jacchus)
… to be either the ventromedial caudate or the putamen. Marmosets were trained on a serial reversal task that allowed multiple acute neural manipulations, and the ventromedial caudate and putamen were then reversibly inactivated using the GABAA agonist muscimol. Results indicated dose-related …

Functionally relevant basal ganglia subdivisions in first-episode schizophrenia
… matter) volumes were obtained for the caudate, putamen, and globus pallidus. For the striatum (caudate and putamen), total and segmented volumes were obtained for their respective sub-regions. These sub-regions were restructured into associative, limbic, and sensorimotor subdivisions. …

Relationship Between CB1 and S1P Receptors in the Central Nervous System
… [35S]GTPγS binding were observed in the caudate putamen, hippocampus, substantia nigra, and cerebellum. To further characterize the relationship between S1P-and CB1-mediated G-protein activation, spinal cords from adult male CB1 receptor knockout mice, CNS-deleted S1Pl receptor knockout mice and …

Investigation of potential biomarkers of treatment-resistant schizophrenia
… glutamate + glutamine (Glx) content in the putamen compared to those with UTRS. Glx levels in the putamen may represent an important biomarker of response to clozapine treatment where levels are higher in those who are responsive and lower in those with UTRS. Reduced white matter integrity …

Effects of HIV on longitudinal development of the fronto-striatal resting state networks in children from 7 to 11 years
… networks. The BG seeds comprised the bilateral putamen, caudate, globus pallidus (GP) and thalamus. Functional regions located in the dorsolateral prefrontal cortex (DLPFC), paracentral lobule and pars opercularis were chosen as frontal ROIs because of their association with executive, motor and …
