Ablation of oligodendrogenesis in adult mice alters brain microstructure and activity independently of behavioural deficits

This study shows that ablating adult oligodendrogenesis alters brain microstructure and activity without affecting behaviour.

Oligodendrocyte dynamics dictate individual performance outcomes of working memory training in mice

The paper shows that oligodendrocyte production is crucial for improving working memory performance in mice during maze training.

Cerebellar GABA change during visuomotor adaptation relates to adaptation performance and cerebellar network connectivity: A Magnetic Resonance Spectroscopic Imaging study.

This study uses MRSI to show GABA changes in the cerebellum during visuomotor adaptation correlate with performance and network connectivity.

tDCS induced GABA change is associated with the simulated electric field in M1, an effect mediated by grey matter volume in the MRS voxel

This paper investigates how the electric field induced by tDCS in the motor cortex correlates with changes in GABA levels, finding that grey matter volume modulates this relationship.

Distributed and gradual microstructure changes track the emergence of behavioural benefit from memory reactivation

This study tracks microstructural changes following memory reactivation during sleep and links them to the emergence of behavioural benefits over time.

Cueing motor memory reactivation during NREM sleep engenders learning-related changes in precuneus and sensorimotor structures

This study shows that reactivating motor memory during sleep increases precuneus activation and predicts long-term benefits, while also causing structural and functional changes in sensorimotor cortex.

Causal evidence of network communication in whole-brain dynamics through a multiplexed neural code

The paper shows how theta frequency modulation enables selective information routing in brain networks, which is impaired in Alzheimer's disease models.

Age-related decline in cortical inhibitory tone strengthens motor memory

The paper shows that age-related decline in cortical inhibitory tone increases motor memory, and this effect depends on the excitation/inhibition balance in sensorimotor cortex.

Reassessing associations between white matter and behaviour with multimodal microstructural imaging

This paper reassesses WM-behaviour relationships using multimodal microstructural imaging in 50 healthy individuals, finding partial support for FA-behaviour links and suggesting multimodal approaches may better capture WM-behaviour associations.

Multimodal imaging brain markers in early adolescence are linked with a physically active lifestyle

The paper links multimodal brain imaging markers in adolescents with physical activity and health measures using canonical correlation analysis.

Hebbian activity-dependent plasticity in white matter

The paper demonstrates that Hebbian plasticity occurs in human white matter, showing increased cortical excitability and myelin markers after co-stimulation of cortical areas.

GABA relates to functional connectivity changes and retention in visuomotor adaptation

The paper investigates how GABA levels and functional connectivity in M1 and cerebellum relate to retention of visuomotor adaptation.

Neurofeedback fMRI in the motor system elicits bi-directional changes in activity and white-matter structure in the healthy adult human brain

This study shows that fMRI neurofeedback can modulate ipsilateral motor cortex activity and induce opposite changes in corpus callosum white matter microstructure in healthy adults.

Experience alterations in white matter structure and myelin-related gene expression in adult rats

This study shows that somatosensory experience in adult rats alters white matter structure and myelin-related gene expression, suggesting myelination as an underlying mechanism.

Skill acquisition increases myelination and strengthens functional connectivity in the sensorimotor circuit of the adult rat

This study shows that skill acquisition in adult rats increases myelination and strengthens functional connectivity in sensorimotor circuits, correlating with improved performance.

Causal explanation of individual differences in human sensorimotor memory formation

The paper identifies neurochemical and computational factors explaining individual differences in sensorimotor memory formation using neuroimaging and transcranial stimulation.

The Role Of Diffusion MRI In Neuroscience

This paper reviews the role of diffusion MRI in neuroscience, highlighting its contributions to understanding white matter anatomy, function, and plasticity, while discussing its limitations and future challenges.
