Cortical plasticity differences in substance use disorders. [PDF]

open access: yesFundam Res
Among substances, opiates and psychostimulants are responsible for the most significant public health problems, yet few studies have characterized their similarities or differences in the cortical plasticity of individuals with these substance related ...

Vagus Nerve Stimulation Induced Motor Map Plasticity Does Not Require Cortical Dopamine

open access: yesFrontiers in Neuroscience, 2021
Background: Vagus nerve stimulation (VNS) paired with motor rehabilitation is an emerging therapeutic strategy to enhance functional recovery after neural injuries such as stroke.

Impairments of motor-cortex responses to unilateral and bilateral direct current stimulation in schizophrenia

open access: yesFrontiers in Psychiatry, 2013
Transcranial direct current stimulation (tDCS) is a non-invasive stimulation technique that can be applied to modulate cortical activity through induction of cortical plasticity.

Familiarization: A theory of repetition suppression predicts interference between overlapping cortical representations. [PDF]

open access: yesPLoS ONE, 2017
Repetition suppression refers to a reduction in the cortical response to a novel stimulus that results from repeated presentation of the stimulus. We demonstrate repetition suppression in a well established computational model of cortical plasticity ...

Heterosynaptic Plasticity in Cortical Interneurons [PDF]

open access: yesThe Journal of Neuroscience, 2020
Persistent alteration of synaptic strength in response to neuronal activity has long been considered a substrate of learning and memory ([Hebb, 1949][1]). Classical Hebbian plasticity results from near-coincidental presynaptic and postsynaptic action potentials (APs), with the precise order ...

The enemy within: propagation of aberrant corticostriatal learning to cortical function in Parkinson's disease

open access: yesFrontiers in Neurology, 2013
Motor dysfunction in Parkinson’s disease is believed to arise primarily from pathophysiology in the dorsal striatum and its related corticostriatal and thalamostriatal circuits during progressive dopamine denervation.

Plasticity in visual cortex is disrupted in a mouse model of tauopathy

open access: yesCommunications Biology, 2022
Amalia Papanikolaou and Fabio Rodrigues et al. examine visual cortical function and intrinsic plasticity using the rTg4510 tauopathy mouse model. They demonstrate that, while basal visual cortical responses seem largely unaffected, intrinsic plasticity ...

Hebbian activity-dependent plasticity in white matter

open access: yesCell Reports, 2022
Summary: Synaptic plasticity is required for learning and follows Hebb’s rule, the computational principle underpinning associative learning. In recent years, a complementary type of brain plasticity has been identified in myelinated axons, which make up

Parvalbumin-Positive Interneurons Regulate Cortical Sensory Plasticity in Adulthood and Development Through Shared Mechanisms

open access: yesFrontiers in Neural Circuits, 2022
Parvalbumin-positive neurons are the largest class of GABAergic, inhibitory neurons in the central nervous system. In the cortex, these fast-spiking cells provide feedforward and feedback synaptic inhibition onto a diverse set of cell types, including ...

Role of Functional Imaging Techniques to Assess Motor and Language Cortical Plasticity in Glioma Patients: A Systematic Review

open access: yesNeural Plasticity, 2019
Cerebral plasticity is the ability of the central nervous system to reorganize itself in response to different injuries. The reshaping of functional areas is a crucial mechanism to compensate for damaged function.
