Metformin Restores Mitochondrial Function and Neurogenesis in POLG Patient‐Derived Brain Organoids
Advanced Science, EarlyView.Patient‐derived POLG‐mutant cortical organoids reveal neuronal subtype‐specific mitochondrial and synaptic defects, with dopaminergic neurons most affected. Metformin treatment restores neuronal identity, mitochondrial function, and excitability, increased mtDNA maintenance, and reprogrammed metabolism via TCA and redox pathways.

Cholinergic modulation of dopamine overflow in the rat neostriatum: A fast cyclic voltammetric study in vitro [PDF]
, 1994 Stimulus-evoked dopamine overflow in rat neostriatal slices was determined using fast cyclic voltammetry. The dopamine efflux induced by intrastriatal stimulation increased with stimulus intensity and was found to be enhanced by more than 100% upon ...

Advanced Science, EarlyView.Impulsivity is a symptom across multiple psychiatric disorders, yet its neural basis remains elusive. This study shows that the NMDAR antagonist MK‐801 elevates dopamine release and disrupts neuronal selectivity in the nucleus accumbens, leading to impulsive behavior.

Dopaminergic Enhancement of Cognitive Function [PDF]
Current Pharmaceutical Design, 2006 The ascending dopamine system of the mammalian brain has been associated with motor, mnemonic and goal-directed or reward-related behaviour. The most progress in understanding the cortical mechanisms of dopaminergic modulation of function has been made with regards to short-term mnemonic (or working memory) function.

Environmental Exposures and Parkinson's Disease. [PDF]
, 2016 Parkinson's disease (PD) affects millions around the world. The Braak hypothesis proposes that in PD a pathologic agent may penetrate the nervous system via the olfactory bulb, gut, or both and spreads throughout the nervous system. The agent is unknown,

Advanced Science, EarlyView.Polyhalogenated carbazoles (PHCZ), persistent environmental contaminants, preferentially accumulate in neuronal tissues. Studies using Caenorhabditis elegans and human neuronal cell lines reveal that PHCZ induce dopaminergic neurodegeneration by promoting liquid–liquid phase separation of α‐synuclein, reducing condensate fluidity, impairing ...

Dissociating Explicit and Implicit Timing in Parkinson\u2019s Disease Patients: Evidence from Bisection and Foreperiod Tasks [PDF]
, 2018 A consistent body of literature reported that Parkinson\u2019s disease (PD) is marked by severe deficits in temporal processing. However, the exact nature of timing problems in PD patients is still elusive.

Advanced Science, EarlyView.Single‐nucleus RNA sequencing of mid‐gestation brains from fetuses with nonsyndromic cleft lip and palate reveals major disruptions in cell composition, cell‐to‐cell signaling, and gene regulation. The transcription factor MEF2C is identified as a central regulator of these changes and shows that lowering MEF2C impairs synapse formation, linking cleft ...

Neuromelanin Imaging and Dopaminergic Loss in Parkinson's Disease
Frontiers in Aging Neuroscience, 2016 Parkinson's disease (PD) is a progressive neurodegenerative disorder in which the major pathologic substrate is a loss of dopaminergic neurons from the substantia nigra.

Effect of hyperthyroidism on circulating prolactin and hypothalamic expression of tyrosine hydroxylase, prolactin signaling cascade members and estrogen and progesterone receptors during late pregnancy and lactation in the rat [PDF]
, 2017 Hyperthyroidism (HyperT) compromises pregnancy and lactation, hindering suckling-induced PRL release. We studied the effect of HyperT on hypothalamic mRNA (RT-qPCR) and protein (Western blot) expression of tyrosine hydroxylase (TH), PRL receptor (PRLR ...
