Synaptic Neuronal Plasticity

Thrita, 2015
Context: The current study aimed to review research articles concerning cortical representational plasticity following the manipulations of inputs. Evidence Acquisition: This review article compromised previous studies in PubMed, Google Scholar and Scientific Information databases according to the keywords since 1988.

Resting state network changes induced by experimental inaudible infrasound exposure and associations with self-reported noise sensitivity and annoyance

Scientific Reports
The effects of prolonged infrasound (IS) exposure on brain function and behavior are largely unknown, with only one prior study investigating functional connectivity (FC) changes.

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.

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.

MiRNAs in Astrocyte-Derived Exosomes as Possible Mediators of Neuronal Plasticity

Journal of Experimental Neuroscience, 2016
Astrocytes use gliotransmitters to modulate neuronal function and plasticity. However, the role of small extracellular vesicles, called exosomes, in astrocyte-to-neuron signaling is mostly unknown.

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 ...

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 ...

Chronic Stress and Glucocorticoids: From Neuronal Plasticity to Neurodegeneration

Journal of Neural Transplantation and Plasticity, 2016
Stress and stress hormones, glucocorticoids (GCs), exert widespread actions in central nervous system, ranging from the regulation of gene transcription, cellular signaling, modulation of synaptic structure, and transmission and glial function 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.
