Subthalamic Nucleus Oscillatory Characteristics in Meige, Cervical Dystonia and Generalized Dystonia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Deep brain stimulation offers a unique opportunity to record neural activity of the basal ganglia. While much work in dystonia has focused on the globus pallidus internus, expanding research to investigate subthalamic nucleus (STN) activity in various dystonia types is critical to provide a comprehensive understanding of dystonia ...

Bone Marrow Contributes Simultaneously to Different Neural Types in the Central Nervous System through Different Mechanisms of Plasticity

Cell Transplantation, 2011
Many studies have reported the contribution of bone marrow-derived cells (BMDC) to the CNS, raising the possibility of using them as a new source to repair damaged brain tissue or restore neuronal function.

Stimulation of the Nigrotectal Pathway at the Level of the Superior Colliculus Reduces Threat Recognition and Causes a Shift From Avoidance to Approach Behavior

Frontiers in Neural Circuits, 2018
Defensive behavioral responses are essential for survival in threating situations. The superior colliculus (SC) has been implicated in the generation of defensive behaviors elicited by visual, tactile and auditory stimuli.

Mean-field theory of a plastic network of integrate-and-fire neurons [PDF]

Phys. Rev. E 81, 011907 (2010), 2009
We consider a noise driven network of integrate-and-fire neurons. The network evolves as result of the activities of the neurons following spike-timing-dependent plasticity rules. We apply a self-consistent mean-field theory to the system to obtain the mean activity level for the system as a function of the mean synaptic weight, which predicts a first ...

Effects of Dalcroze Eurhythmics Exercise Versus Multicomponent Exercise on Physical and Cognitive Function, and Falls in Older Adults: The EPHYCOS Randomized Controlled Trial

Advanced Biology, EarlyView.
In this randomized clinical trial conducted among 142 community‐dwelling older adults at high risk for falls over 12 months, a Dalcroze Eurhythmics exercise intervention (once weekly, group‐based) improved a variety of physical and cognitive/executive function outcomes compared with a multicomponent exercise intervention (twice weekly, group‐ and home ...

Differences in hippocampal plasticity and memory outcomes in anterior versus posterior cerebellar stroke

Neurobiology of Disease, 2022
Neurological symptoms following cerebellar stroke can range from motor to cognitive-affective impairments. Topographic imaging studies from patients with lesions confined to the cerebellum have shown evidence linking anterior cerebellar lobules with ...

Impaired synaptic incorporation of AMPA receptors in a mouse model of fragile X syndrome

Frontiers in Molecular Neuroscience, 2023
Fragile X syndrome (FXS) is the most common monogenetic cause of inherited intellectual disability and autism in humans. One of the well-characterized molecular phenotypes of Fmr1 KO mice, a model of FXS, is increased translation of synaptic proteins ...

Theory of coupled neuronal-synaptic dynamics [PDF]

arXiv, 2023
In neural circuits, synaptic strengths influence neuronal activity by shaping network dynamics, and neuronal activity influences synaptic strengths through activity-dependent plasticity. Motivated by this fact, we study a recurrent-network model in which neuronal units and synaptic couplings are interacting dynamic variables, with couplings subject to ...

Mild Cerebellar Neurodegeneration of Aged Heterozygous PCD Mice Increases Cell Fusion of Purkinje and Bone Marrow-Derived Cells

Cell Transplantation, 2012
Bone marrow-derived cells have different plastic properties, especially regarding cell fusion, which increases with time and is prompted by tissue injury.
