Dopaminergic presynaptic modulation of nigral afferents: its role in the generation of recurrent bursting in substantia nigra pars reticulata neurons

Frontiers in Systems Neuroscience, 2011
Previous work has shown the functions associated with activation of dopamine presynaptic receptors in some substantia nigra pars reticulata (SNr) afferents: i) striatonigral terminals (direct pathway) posses presynaptic dopamine D1-class receptors whose ...

Beta band modulation by dopamine D2 receptors in the primary motor cortex and pedunculopontine nucleus in a rat model of Parkinson’s disease

Brain Research Bulletin, 2022
Beta band (12–30 Hz) hypersynchrony within the basal ganglia-thalamocortical network has been suggested as a hallmark of Parkinson’s disease (PD) pathophysiology. Abnormal beta band oscillations are found in the pedunculopontine nucleus (PPN) and primary

Autism and Cortical Thickness Deviation From Neurotypical Controls: Evidence for a Spatial Association With Serotonin Receptors

Autism Research, EarlyView.
ABSTRACT Cortical thickness (CT) differences between autistic individuals (AI) and neurotypical controls have been consistently reported, yet the neurochemical mechanisms underlying these differences remain insufficiently understood. Neurotransmitter receptor systems exhibit distinct spatial distributions across the cortex and influence synaptic ...

Reduced GABA-B/GIRK-mediated regulation of the VTA following a single exposure to cocaine [PDF]

, 2012
In this paper, Arora and colleagues expand on their previous work on GIRK channels in the ventral tegmental area (VTA) presenting evidence that a single exposure to cocaine reduces inhibitory GABAergic transmission to dopamine (DA) neurons in the ventral

Clinical pharmacology and prescribing education: An updated medical school curriculum from the British Pharmacological Society

British Journal of Clinical Pharmacology, EarlyView.
Aims Prescribing is a complex, essential skill that doctors must acquire to practice medicine safely and effectively. The British Pharmacological Society has historically provided a core curriculum to guide clinical pharmacology and prescribing education in UK medical schools.

Dopamine D2 antagonist-induced striatal Nur77 expression requires activation of mGlu5 receptors by cortical afferents

Frontiers in Pharmacology, 2012
Dopamine D2 receptor antagonists modulate gene transcription in the striatum. However, the molecular mechanism underlying this effect remains elusive. Here we used the expression of Nur77, a transcription factor of the orphan nuclear receptor family, as ...

Genomic Insights Into Risperidone Treatment Outcomes in Children and Adolescents: Experience From a Psychiatric Hospital Serving Rural Youth

Clinical Pharmacology &Therapeutics, EarlyView.
Risperidone is a commonly used antipsychotic for treating psychiatric illness in children and adolescents. There is a large variability in risperidone response and discontinuation rates remain high. Pharmacogenomics offers the opportunity to improve risperidone outcomes, yet studies in pediatric populations are limited.

Preservation of dendritic D2 receptor transmission in substantia nigra dopamine neurons with age

Scientific Reports, 2023
Substantia nigra pars compacta (SNc) dopamine neurons are required for voluntary movement and reward learning, and advanced age is associated with motor and cognitive decline.
