The study identifies BTBR/R mice as a more accurate model of autism, exhibiting autistic-like behaviors without reduced learning ability.
Researchers at the HSE Centre for Language and Brain found that a thicker corpus callosum is associated with less lateralization of language functions to the right hemisphere. The study used advanced neuroimaging methods, including fMRI, to measure brain activity while participants completed a sentence completion task.
A prospective multicenter case-control study found that third-trimester fetuses exposed to opioids in utero exhibited smaller brain biometric measurements and altered fetal physiology. The study suggests a possible link between prenatal opioid exposure and postnatal clinical outcomes.
Researchers found unique fingerprints of hypoplasia and agenesis in corpus callosum dysgenesis, using distinct plastic mechanisms to compensate for partial or complete lack of the corpus callosum. This discovery sheds light on brain plasticity and its relation to symptoms in patients with this condition.
Researchers from UNIGE discovered that when the neuronal fibres connecting the hemispheres are missing, the brain reorganises itself and creates new connections. Intra-hemispheric connections increase, enabling communication between the two hemispheres to be maintained.
A new study on rare 'split brain' patients demonstrates that NREM-sleep slow waves propagate in the human brain through cortical anatomical connections, contradicting common beliefs about sleep as a uniform state. The research found that each area of the brain may produce its own
Researchers found that professional drummers have fewer but thicker fibres in the corpus callosum, a brain structure responsible for motor planning. This leads to more efficient brain organisation and better performance in drumming tasks. The study also revealed that drummers' brains are less active in motor tasks.
