Deep brain stimulation for movement disorder treatment: Exploring frequency-dependent efficacy in a computational network model [PDF]

open access: yesarXiv, 2020
A large scale computational model of the basal ganglia (BG) network is proposed to describes movement disorder including deep brain stimulation (DBS). The model of this complex network considers four areas of the basal ganglia network: the subthalamic nucleus (STN) as target area of DBS, globus pallidus, both pars externa and pars interna (GPe-GPi ...

A Computational Model of the Effects of Drug Addiction on Neural Population Dynamics [PDF]

open access: yesarXiv, 2012
Reward processing and derangements thereof, such as drug addiction, involve the coordinated activity of many brain areas. Prior work has identified many behavioral, molecular biological and single neuron changes throughout the mesocorticolimbic system that reflect and drive addictive behavior.

Antidepressant-like Effects of Neuropeptide SF (NPSF) [PDF]

open access: yesWorld Journal of Research and Review (WJRR) ISSN:2455-3956, Volume-4, Issue-5, May 2017 Pages 26-30, 2020
Neuropeptide SF (NPSF) is a member of RFamide neuropeptides that play diverse roles in central nervous system. Little is know about the effects of NPSF on brain functions. Antidepressant-like effect of NPSF was studied in modified mice FST. NPSF showed the antidepressant-like effects by decreasing the immobility time and increasing the climbing and ...

Zeb2 is a negative regulator of midbrain dopaminergic axon growth and target innervation

open access: yesScientific Reports, 2017
Neural connectivity requires neuronal differentiation, axon growth, and precise target innervation. Midbrain dopaminergic neurons project via the nigrostriatal pathway to the striatum to regulate voluntary movement.

Efficient conversion of astrocytes to functional midbrain dopaminergic neurons using a single polycistronic vector.

open access: yesPLoS ONE, 2011
Direct cellular reprogramming is a powerful new tool for regenerative medicine. In efforts to understand and treat Parkinson's Disease (PD), which is marked by the degeneration of dopaminergic neurons in the midbrain, direct reprogramming provides a ...

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

open access: yesarXiv, 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 ...

Proteolytic activation of proapoptotic kinase protein kinase Cδ by tumor necrosis factor α death receptor signaling in dopaminergic neurons during neuroinflammation

open access: yesJournal of Neuroinflammation, 2012
Background The mechanisms of progressive dopaminergic neuronal loss in Parkinson’s disease (PD) remain poorly understood, largely due to the complex etiology and multifactorial nature of disease pathogenesis.

Transdifferentiation of Human Umbilical Cord-Derived Mesenchymal Stem Cells in Dopaminergic Neurons in a Three-Dimensional Culture

open access: yesBasic and Clinical Neuroscience, 2022
Introduction: The induction of human umbilical cord-derived mesenchymal stem cells (HUC-MSCs) toward dopaminergic neurons is a major challenge in tissue engineering and experimental and clinical treatments of various neurodegenerative diseases, including

An Explainable Machine Learning Model for Early Detection of Parkinson's Disease using LIME on DaTscan Imagery [PDF]

open access: yesarXiv, 2020
Parkinson's disease (PD) is a degenerative and progressive neurological condition. Early diagnosis can improve treatment for patients and is performed through dopaminergic imaging techniques like the SPECT DaTscan. In this study, we propose a machine learning model that accurately classifies any given DaTscan as having Parkinson's disease or not, in ...

Speech and Language Development in children with hyperkinetic disorder in children under conditions of pathogenetic heterogeneity

open access: yesОбозрение психиатрии и медицинской психологии имени В.М. Бехтерева, 2018
The frequency and expected mechanisms of comorbidity of hyperkinetic disorder with dyslasia, dyslexia, dysgraphia and dyscalculia are considered in the article.
