Subcellular expression and neuroprotective effects of SK channels in human dopaminergic neurons

Cell Death and Disease, 2014
Small-conductance Ca2+-activated K+ channel activation is an emerging therapeutic approach for treatment of neurological diseases, including stroke, amyotrophic lateral sclerosis and schizophrenia.

GABAergic modulation of beta power enhances motor adaptation in frontotemporal lobar degeneration

Alzheimer's &Dementia, EarlyView.
Abstract INTRODUCTION We examined how abnormal prefrontal neurophysiology and changes in gamma‐aminobutyric acid‐ergic (GABAergic) neurotransmission contribute to behavioral impairments in disorders associated with frontotemporal lobar degeneration (FTLD). METHODS We recorded magnetoencephalography during an adaptive visuomotor task from 11 people with

Reinforcement Learning in a Neurally Controlled Robot Using Dopamine Modulated STDP [PDF]

arXiv, 2015
Recent work has shown that dopamine-modulated STDP can solve many of the issues associated with reinforcement learning, such as the distal reward problem. Spiking neural networks provide a useful technique in implementing reinforcement learning in an embodied context as they can deal with continuous parameter spaces and as such are better at ...

Microglial ApoD‐induced NLRC4 inflammasome activation promotes Alzheimer's disease progression

Animal Models and Experimental Medicine, EarlyView.
We found that NLRC4 inflammasome was activated in microglia releasing IL6 and TNF‐α to impair the hippocampal neural stem cells (NSCs) self‐proliferation. ApoD contributed to activating NLRC4 inflammasome in microglia. Targeting the ApoD provides beneficial effects on NSCs self‐proliferation and mature neurons survival.

Co-operativity in neurons and the role of noise in brain [PDF]

arXiv, 2007
In view of some recent results in case of the dopaminergic neurons exhibiting long range correlations in VTA of the limbic brain we are interested to find out whether any stochastic nonlinear response may be reproducible in the nano scales usimg the results of quantum mechanics.

Targeting signaling pathways in neurodegenerative diseases: Quercetin's cellular and molecular mechanisms for neuroprotection

Animal Models and Experimental Medicine, EarlyView.
Quercetin regulates signaling pathways in neurodegenerative diseases, including NF‐κB, sirtuins, and PI3K/Akt. Studies show quercetin improves symptoms and pathology in neurodegenerative models. The study aims to incorporate laboratory research into practical medical treatment, focusing on quercetin's neuroprotective effects and optimal dosage ...

Reinforcement learning with a network of spiking agents [PDF]

arXiv, 2019
Neuroscientific theory suggests that dopaminergic neurons broadcast global reward prediction errors to large areas of the brain influencing the synaptic plasticity of the neurons in those regions. We build on this theory to propose a multi-agent learning framework with spiking neurons in the generalized linear model (GLM) formulation as agents, to ...

Effects of pregnancy on neuron electrophysiology in prefrontal cortex, hippocampus, and basolateral amygdala of mouse brain

Animal Models and Experimental Medicine, EarlyView.
The electrophysiological change in neurons might contribute to the cognitive and emotional changes during pregnancy. Abstract Background Pregnancy affects learning and memory in women. Thus, to investigate the effects of pregnancy, the authors examined the brain electrophysiology of pregnant mice.

Validating the Accuracy of Parkinson's Disease Clinical Diagnosis: A UK Brain Bank Case–Control Study

Annals of Neurology, EarlyView.
Objective Despite diagnostic criteria refinements, Parkinson's disease (PD) clinical diagnosis still suffers from a not satisfying accuracy, with the post‐mortem examination as the gold standard for diagnosis. Seminal clinicopathological series highlighted that a relevant number of patients alive‐diagnosed with idiopathic PD have an alternative post ...
