Myelin basic protein mRNA levels affect myelin sheath dimensions, architecture, plasticity, and density of resident glial cells

Author(s): Bagheri H; Friedman H; Hadwen A; Jarweh C; Cooper E; Oprea L; Guerrier C; Khadra A; Collin A; Cohen-Adad J; Young A; Victoriano GM; Swire M; ...

Myelin basic protein (Mbp) is essential for both elaboration and maintenance of CNS myelin, and its reduced accumulation results in hypomyelination. How different Mbp mRNA levels affect myelin dime ...

Cross-modal plasticity in children with cochlear implant: converging evidence from EEG and functional near-infrared spectroscopy

Author(s): Deroche MLD; Wolfe J; Neumann S; Manning J; Hanna L; Towler W; Wilson C; Bien AG; Miller S; Schafer E; Gemignani J; Alemi R; Muthuraman M; K ...

Over the first years of life, the brain undergoes substantial organization in response to environmental stimulation. In a silent world, it may promote vision by (i) recruiting resources from the au ...

Decreased long-range temporal correlations in the resting-state functional magnetic resonance imaging blood-oxygen-level-dependent signal reflect motor sequence learning up to 2 weeks following training

Author(s): Jäger AP; Bailey A; Huntenburg JM; Tardif CL; Villringer A; Gauthier CJ; Nikulin V; Bazin PL; Steele CJ; ...

Decreased long-range temporal correlations (LRTC) in brain signals can be used to measure cognitive effort during task execution. Here, we examined how learning a motor sequence affects long-range ...

Audiovisual integration in children with cochlear implants revealed through EEG and fNIRS

Author(s): Alemi R; Wolfe J; Neumann S; Manning J; Towler W; Koirala N; Gracco VL; Deroche M;

Sensory deprivation can offset the balance of audio versus visual information in multimodal processing. Such a phenomenon could persist for children born deaf, even after they receive cochlear implants (CIs), and could potentially explain why one modality i ...

Olfaction and reaction: The role of olfactory and hypothalamic investment in the antipredator responses to chemical alarm cues by northern redbelly dace

Author(s): Joyce BJ; Brown GE;

Neuroplasticity enables teleosts to promote or downregulate the growth of their brains regionally. To compensate for the effects of predation pressure, teleosts may alter their brain morphology and behavioral responses to mitigate its impact on individual f ...

Using cortico-cerebellar structural patterns to classify early- and late-trained musicians

Author(s): Shenker JJ; Steele CJ; Zatorre RJ; Penhune VB;

A body of current evidence suggests that there is a sensitive period for musical training: people who begin training before the age of seven show better performance on tests of musical skill, and also show differences in brain structure-especially in motor ...

Visuo-motor transformations in the intraparietal sulcus mediate the acquisition of endovascular medical skill

Author(s): Paul KI; Mueller K; Rousseau PN; Glathe A; Taatgen NA; Cnossen F; Lanzer P; Villringer A; Steele CJ; ...

Performing endovascular medical interventions safely and efficiently requires a diverse set of skills that need to be practised in dedicated training sessions. Here, we used multimodal magnetic res ...

Early musical training shapes cortico-cerebellar structural covariation

Author(s): Shenker JJ; Steele CJ; Chakravarty MM; Zatorre RJ; Penhune VB;

Adult abilities in complex cognitive domains such as music appear to depend critically on the age at which training or experience begins, and relevant experience has greater long-term effects during periods of peak maturational change. Previous work has sho ...

Neurobehavioral, neurochemical and synaptic plasticity perturbations during postnatal life of rats exposed to chloroquine in-utero

Author(s): Olajide OJ; Alliy ZO; Ojo DO; Osinubi OO; Bello SO; Ibrahim FE; Adukwu FO; Abikoye TO; Gbadamosi IT; Mutholib NY; Bamisi O; Ajiboye OJ; Okes ...

Despite reports that quinoline antimalarials including chloroquine (Chq) exhibit idiosyncratic neuropsychiatric effects even at low doses, the drug continues to be in widespread use during pregnanc ...

White matter microstructural changes in short-term learning of a continuous visuomotor sequence

Author(s): Tremblay SA; Jäger AT; Huck J; Giacosa C; Beram S; Schneider U; Grahl S; Villringer A; Tardif CL; Bazin PL; Steele CJ; Gauthier CJ; ...

Efficient neural transmission is crucial for optimal brain function, yet the plastic potential of white matter (WM) has long been overlooked. Growing evidence now shows that modifications to axons ...

Evaluating the correlation between genome-wide diversity and the release of plastic phenotypic variation in experimental translocations to novel natural environments.

Author(s): Yates MC, Fraser DJ

Phenotypic reaction norms are often shaped and constrained by selection and are important for allowing organisms to respond to environmental change. However, selection cannot constrain reaction norms for environmental conditions that populations have not ex ...
