Clinical features and power spectral entropy of electroencephalography in Wilson's disease with dystonia

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022
WD patients with dystonia were more susceptible to suffer from low BMI and highߚlevel neurological dysfunctions. It was the first time to apply the PSE of EEG to detect the cortical synaptic activity in WD patients. The cortical activities of the WD patients with dystonia seemed to be more chaotic during the eyes‐closed and reading tasks but lower ...

Sirt3 protects dopaminergic neurons from mitochondrial oxidative stress

Human Molecular Genetics, 2017
&NA; Age‐dependent elevation in mitochondrial oxidative stress is widely posited to be a major factor underlying the loss of substantia nigra pars compacta (SNc) dopaminergic neurons in Parkinson's disease (PD).

Quantitative electroencephalographic analysis of delirium tremens development following alcohol‐withdrawal seizure based on a small number of male cases

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022
Considering the complications related to alcohol withdrawal syndrome (AWS) such as seizure, delirium tremens and cardiac arrhythmia, it is important to identify the risk of delirium tremens (DT) following AWS and enhance preventive strategies. We observed the characteristics of quantitative electroencephalography in patients with AWS, specifically who ...

Direct Glutamatergic Signaling From Midbrain Dopaminergic Neurons Onto Pyramidal Prefrontal Cortex Neurons

Frontiers in Neural Circuits, 2018
The dopaminergic neurons of the ventral tegmental area (VTA) have been identified with the ability to co-release dopamine and glutamate. This ability was first documented in the nucleus accumbens but showed to be absent in the dorsal striatum.

Arecoline Induces an Excitatory Response in Ventral Tegmental Area Dopaminergic Neurons in Anesthetized Rats

Frontiers in Pharmacology, 2022
Arecoline is the principle psychoactive alkaloid in areca nuts. Areca nuts are chewable seeds of Areca catechu L., which are epidemic plants that grow in tropical and subtropical countries and cause dependency after long-term use. However, the mechanisms

Representation learning with reward prediction errors [PDF]

arXiv, 2021
The Reward Prediction Error hypothesis proposes that phasic activity in the midbrain dopaminergic system reflects prediction errors needed for learning in reinforcement learning. Besides the well-documented association between dopamine and reward processing, dopamine is implicated in a variety of functions without a clear relationship to reward ...

Licochalcone A Prevents the Loss of Dopaminergic Neurons by Inhibiting Microglial Activation in Lipopolysaccharide (LPS)-Induced Parkinson’s Disease Models

International Journal of Molecular Sciences, 2017
The neuroprotective effects of Licochalcone A (Lico.A), a flavonoid isolated from the herb licorice, in Parkinson’s disease (PD) have not been elucidated. The prominent pathological feature of PD is the loss of dopaminergic neurons.

A simplified model of dopaminergic neuron [PDF]

BMC Neuroscience, 2008
A minimal model of a dopamine cell in vitro in the pres-ence of tetrodoxin (TTX) and tetraethyl ammonium (TEA)was developed to simulate two types of subthresholdoscillations: the slow oscillatory potential (SOP – see Fig-ure 1A) and the square wave (Figure 1B) that can be pro-duced by the abolition of the SOP by apamin. The L-typecalcium current drives

Levodopa responsiveness and white matter alterations in Parkinson's disease: A DTI‐based study and brain network analysis: A cross‐sectional study

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Background Patients with Parkinson's disease (PD) present various responsiveness to levodopa, but the cause of such differences in levodopa responsiveness is unclear. Previous studies related the damage of brain white matter (WM) to levodopa responsiveness in PD patients, but no study investigated the relationship between the structural brain ...

Can linking the recall system to addiction enable a better understanding of the dopaminergic pathway? [PDF]

arXiv, 2022
Human addiction, as a learned behaviour, has and is constantly being treated psychologically, with specific and timely interventions from Neuroscience. We endorse that human addiction can receive further boost as regards treatment, when we firmly understand how it works from a quantum scale. This is majorly because the dopaminergic pathway (DP) that is
