Fifteen‐Year Outcomes of Bilateral Pallidal Stimulation in Isolated Generalized Dystonia: Characterization of Therapeutic Response and Emergence of Parkinsonism

Movement Disorders, EarlyView.
Abstract Background Bilateral pallidal deep brain stimulation (GPi‐DBS) is effective for dystonia. Long‐term evolution of therapeutic benefit and emergence of parkinsonism have not been systematically characterized. Objectives To assess 15‐year dystonia outcomes and characterize parkinsonism after bilateral GPi‐DBS.

Decisional impulsivity and the associative-limbic subthalamic nucleus in obsessive-compulsive disorder: stimulation and connectivity. [PDF]

, 2017
Why do we make hasty decisions for short-term gain? Rapid decision-making with limited accumulation of evidence and delay discounting are forms of decisional impulsivity.

Linking actions to outcomes : the role of the posterior pedunculopontine tegmental nucleus in instrumental learning [PDF]

, 2012
Located in the mesopontine tegmentum, the pedunculopontine tegmental nucleus (PPTg) is comprised principally of glutamatergic, cholinergic and GABAergic neurons.

Dopamine Agonists Rather than Deep Brain Stimulation Cause Reflection Impulsivity in Parkinson's Disease

Journal of Parkinson’s Disease, 2013
Background: Dopamine agonist therapy is the main risk factor for impulse control disorders in Parkinson's disease (PD). However, it is unclear whether bilateral deep brain stimulation of the subthalamic nucleus also causes impairment in decision making ...

Decoding neuronal vulnerability: Multidimensional analysis of D1R‐ and D2R‐ medium‐sized spiny neurons in Huntington's disease

Brain Pathology, EarlyView.
D1R and D2R MSNs show distinct responses to Huntington's pathology. G&T‐sequencing of pre‐symptomatic MSNs reveals global LINE‐1 downregulation. While D1R‐MSNs display early transcriptomic changes (OXPHOS/translation upregulation) and reduced mutant huntingtin aggregation, D2R‐MSNs exhibit higher nuclear mHTT accumulation and greater CAG somatic ...

Deep brain stimulation promotes excitation and inhibition in subthalamic nucleus in Parkinson's disease

, 2008
Subthalamic nucleus single-unit recordings were undertaken before and during pedunculopontine [corrected] nucleus-stimulation at clinically relevant frequency (25 Hz) in six patients with Parkinson's disease.

In silico prediction of novel effective combinational treatment of chronic pain in individual patients: A joint white paper of the H2020 QSPainRelief consortium

British Journal of Pharmacology, EarlyView.
Abstract Opioids are prescribed widely for chronic pain despite well‐recognised risks and variable long‐term benefit, reflecting the lack of effective alternatives for many patients. Combination therapies offer a promising strategy to enhance efficacy whilst reducing side effects.

Synaptic release of dopamine in the subthalamic nucleus

European Journal of Neuroscience, 2004
AbstractThe direct modulation of subthalamic nucleus (STN) neurons by dopamine (DA) neurons of the substantia nigra (SN) is controversial owing to the thick caliber and low density of DA axons in the STN. The abnormal activity of the STN in Parkinson's disease (PD), which is central to the appearance of symptoms, is therefore thought to result from the

Potentiation effects of the positive allosteric modulator PTC‐174 on NMDA receptors in neonatal male rat substantia nigra dopaminergic neurons

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Positive allosteric modulators bind to secondary binding sites on the receptor and alter receptor conformation and activation, changing agonist potency and efficacy. PTC‐174 is a novel NMDA receptor positive allosteric modulator that particularly enhances activity of receptors containing GluN2C or GluN2D subunits.
