Beyond the basal ganglia
… has mainly focused on the role of the basal ganglia. Dysfunction of these brain nuclei likely underlies motor disturbances in HD, including the conspicuous, uncontrollable, dance-like movements (chorea). However, HD is frequently complicated by other important signs and symptoms that cannot, …

Speech disorders and lesions of the Basal Ganglia
… disorders consequent upon lesions of the basal ganglia. For many years it was assumed that the speech disorders associated with basal ganglia damage were no more than a manifestation of underlying rigidity. However, experience has shown that surgery which successfully ameliorates the rigidity in …

Social Cognition in Disorders of the Basal Ganglia
Patients with disorders of the basal ganglia, such as Parkinson’s disease, Huntington’s disease and Tourette’s Syndrome, exhibit characteristic motor symptoms and less obvious cognitive deficits. These deficits can be understood with reference to the model of cortico-striato-thalamo-cortical …

Functionally relevant basal ganglia subdivisions in first-episode schizophrenia
… the pathophysiology remains unclear. The basal ganglia, a region of the brain involved in motor, cognitive, and sensory processes, may be involved in the pathophysiology of schizophrenia. Some, but not all, neuroimaging studies suggest abnormalities of the basal ganglia in schizophrenia. …

Pathobiology of neuroinflammation and basal ganglia circuitry in Parkinson’s Disease
… death of dopaminergic neurons in a basal ganglia nucleus termed the substantia nigra (SN). Another hallmark feature of PD pathology is the presence of Lewy bodies and Lewy neurites, which are cellular inclusions with aggregated protein depositions, representing pathology in neuronal cell …

Cortical - Basal Ganglia Circuits: Control of Behaviour and Alcohol Misuse
… form and unite to link the cortex with the basal ganglia and thalamus to mediate movement, cognition and behaviour. Previous assertions that the basal ganglia primarily acted to filter cortical information to facilitate motor outputs only have since given way to an understanding of the basal …

The Role of the Cortico-Basal Ganglia-System in Voluntary Movements
… of motor circuits in the cortex and basal ganglia in the consciously behaving rodent during the execution of various motor behaviors. To be able to further explore the relevance of neuronal activation patterns for different behaviours within these motor structures, we developed two methods …

Neural Dynamics in the Basal Ganglia Underlying Birdsong Practice and Performance
… that spiny neurons (SNs) in the basal ganglia (BG) encode vocal variability during solo practice, and that SN activity is strongly suppressed to enable stereotyped song performance towards a female. Second, I showed that optogenetically inhibiting SNs reduces pitch variability to …

The Role of the Basal Ganglia in Memory and Motor Inhibition
… PhD thesis investigated the role of the basal ganglia in memory and motor inhibition. Recent neuroimaging evidence suggests a supramodal network of inhibition involving the lateral prefrontal cortex. Here we examined whether this supramodal network also includes subcortical structures, such as …

Visualization of neuronal geometry in ventral nerve cord ganglia of Acheta domesticus
… of various nerves leading to their respective ganglia (Fig. 1) and to obtain visualization of the finest terminal branches. A description of the cellular arrangement of a segmental ganglion would be of value in better understanding the results obtained when using the axonal iontophoresis method …

Segmentation of nerve bundles and ganglia in spine MRI using particle filters
… that enables delineation of nerve bundles and ganglia from the surrounding anatomical structures. We evaluate the results by comparing them to expert manual segmentation, and we demonstrate accurate and fast nerve tracking.

Perceptual Organization in Parkinson’s Disease: A Behavioral Investigation of Basal Ganglia Dysfunction
The basal ganglia provide a major neural system through which the cortex affects behavior. Most notable among these effects are those related to the voluntary control of movement as seen in neurodegenerative disorders like Parkinson’s disease (PD). Well known tests of visual perception in PD …

A microfluidic culture for two populations of dorsal root ganglia for differential staining
… distinguish the two populations of dorsal root ganglia (DRGs) by differential staining. Polydimethylsiloxane (PDMS) is the most widely used silicon-based organic polymer, and is particularly known for its wide spread use in microfluidics. Various methods have been employed to pump fluids in …

Identification of Connexins in Facilitating Neuron-Satellite Glial Cell Signaling in Trigeminal Ganglia
Activation of trigeminal nerves in response to an inflammatory stimulus causes increased communication between neurons and surrounding satellite glial cells via gap junctions in the trigeminal ganglion (TG). The goal of this study was to identify the gap junction proteins, or connexins (Cxs), in …

Effects of Advancing Age on ER Calcium Regulation in Rat Superior Cervical Ganglia
<p>Intracellular calcium ([Ca<sup>2+</sup>]i) release from endoplasmic reticulum (ER) stores plays an important role in cell signaling. These stores are rapidly refilled via voltage-gated calcium channels or spontaneously via store-operated calcium channels and subsequent pumping by ER …
