Although Parkinson's disease (PD) is characterized primarily by loss of nigrostriatal dopaminergic neurons, there a concomitant norepinephrine (NE) neurons in the locus coeruleus. Dopaminergic lesions induced 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) are commonly used to model PD, and although MPTP effectively mimics neuropathology PD mice, it fails produce PD-like motor deficits. We hypothesized that unable recapitulate abnormalities either because behavioral paradigms measure...

The basal ganglia are comprised of the striatum, external and internal segment globus pallidus (GPe GPi, respectively), subthalamic nucleus (STN), substantia nigra pars compacta reticulata (SNc SNr, respectively). Dopamine has long been identified as an important modulator function in disturbances striatal dopaminergic transmission have implicated diseases such Parkinson's disease (PD), addiction attention deficit hyperactivity disorder. However, recent evidence suggests that dopamine may...

Abstract Researchers are rapidly developing and deploying highly portable MRI technology to conduct field-based research. The new will widen access include investigators in remote unconventional settings facilitate greater inclusion of rural, economically disadvantaged, historically underrepresented populations. To address the ethical, legal, societal issues raised by accessible MRI, an interdisciplinary Working Group (WG) engaged a multi-year structured process analysis consensus building,...

Stigma against patients with functional neurological disorder (FND) presents obstacles to diagnosis, treatment, and research. The lack of biomarkers the potential for symptoms be misunderstood, invalidated, or dismissed can leave patients, families, healthcare professionals at a loss. exacerbates suffering unmet needs result in poor clinical management prolonged, repetitive use resources. Our current understanding stigma FND comes from surveys documenting frustration experienced by providers...

The subthalamic nucleus (STN) receives a dopaminergic innervation from the substantia nigra pars compacta, but role of this projection remains poorly understood, particularly in primates. To address issue, we used immuno-electron microscopy to localize D1, D2, and D5 dopamine receptors STN rhesus macaques studied electrophysiological effects activating D1-like or D2-like normal 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated parkinsonian monkeys. Labeling D1 D2 was primarily...

<h3>SUMMARY:</h3> With rapid advances in neuroimaging technology, there is growing concern over potential misuse of neuroradiologic imaging data legal matters. On December 7 and 8, 2012, a multidisciplinary consensus conference, Use Abuse Neuroimaging the Courtroom, was held at Emory University Atlanta, Georgia. Through this interactive forum, highly select group experts—including neuroradiologists, neurologists, forensic psychiatrists, neuropsychologists, neuroscientists, scholars,...

According to traditional models of the basal ganglia-thalamocortical network connections, dopamine exerts D2-like receptor (D2LR)-mediated effects through actions on striatal neurons that give rise "indirect" pathway, secondarily affecting activity in internal and external pallidal segments (GPi GPe, respectively) substantia nigra pars reticulata (SNr). However, accumulating evidence from rodent literature suggests D2LR activation also directly influences synaptic transmission these nuclei....

Enhanced adult hippocampal neurogenesis and increased trophic factor expression mediate the behavioral effects of antidepressants. We investigated influence alpha2‐adrenoceptors on neurogenesis. found that alpha2 agonists selectively decrease progenitor proliferation. These persist in Dbh−/− mice lacking norepinephrine, suggesting an action through alpha2‐heteroceptors. Adult progenitors express all alpha2‐adrenoceptor subtypes, decreased neurosphere frequency BrdU incorporation indicate...
