Neurogranin Regulates Metaplasticity

open access: yesFrontiers in Molecular Neuroscience, 2020
Long-term potentiation (LTP) and long-term depression (LTD) are two major forms of synaptic plasticity that are widely accepted as cellular mechanisms involved in learning and memory.

Train duration and inter-train interval determine the direction and intensity of high-frequency rTMS after-effects

open access: yesFrontiers in Neuroscience, 2023
Background and objectiveIt has been proved that repetitive transcranial magnetic stimulation (rTMS) triggers the modulation of homeostatic metaplasticity, which causes the effect of rTMS to disappear or even reverse, and a certain length of interval ...

A Systematic Review of the Safety and Tolerability of Theta Burst Stimulation in Children and Adolescents

open access: yesNeuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Theta burst stimulation (TBS) is often used in clinical practice and research protocols for adults with neuropsychiatric disorders. There are substantial knowledge gaps related to the application of TBS in children and adolescents.

Structural plasticity can produce metaplasticity. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Synaptic plasticity underlies many aspect of learning memory and development. The properties of synaptic plasticity can change as a function of previous plasticity and previous activation of synapses, a phenomenon called metaplasticity ...

Spinal Metaplasticity in Respiratory Motor Control

open access: yesFrontiers in Neural Circuits, 2015
A hallmark feature of the neural system controlling breathing is its ability to exhibit plasticity. Less appreciated is the ability to exhibit metaplasticity, a change in the capacity to express plasticity (ie. plastic plasticity). Recent advances in our

Enhanced polychronisation in a spiking network with metaplasticity

open access: yesFrontiers in Computational Neuroscience, 2015
Computational models of metaplasticity have usually focused on the modeling of single synapses (Shouval et al., 2002). In this paper we study the effect of metaplasticity on network behavior.

Accumulation of Dense Core Vesicles in Hippocampal Synapses Following Chronic Inactivity. [PDF]

open access: yes, 2018
The morphology and function of neuronal synapses are regulated by neural activity, as manifested in activity-dependent synapse maturation and various forms of synaptic plasticity.

Morphological Responses of Excitatory Prelimbic and Orbitofrontal Cortical Neurons to Excess Corticosterone in Adolescence and Acute Stress in Adulthood

open access: yesFrontiers in Neuroanatomy, 2020
Considerable evidence indicates that chronic stress and excess glucocorticoids induce neuronal remodeling in prefrontal cortical (PFC) regions. Adolescence is also characterized by a structural reorganization of PFC neurons, yet interactions between ...

The Effects of Priming Intermittent Theta Burst Stimulation on Movement-Related and Mirror Visual Feedback-Induced Sensorimotor Desynchronization

open access: yesFrontiers in Human Neuroscience, 2021
The potential benefits of priming intermittent theta burst stimulation (iTBS) with continuous theta burst stimulation (cTBS) have not been examined in regard to sensorimotor oscillatory activities recorded in electroencephalography (EEG).

CaMKII Metaplasticity Drives Aβ Oligomer-Mediated Synaptotoxicity

open access: yesCell Reports, 2018
Summary: Alzheimer’s disease (AD) is emerging as a synaptopathology driven by metaplasticity. Indeed, reminiscent of metaplasticity, oligomeric forms of the amyloid-β peptide (oAβ) prevent induction of long-term potentiation (LTP) via the prior ...
