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.
A new study reveals that concussion damage affects the way information is transmitted between brain hemispheres. Researchers found a delay in reaction time when processing words presented to the left visual field, indicating a problem with information crossing from one hemisphere to another.
A new study found a link between prenatal exposure to particulate matter and structural changes in the corpus callosum, associated with ADHD and ASD. Children exposed to higher levels of PM2.5 showed reduced corpus callosum volume and increased hyperactivity.
Researchers suggest that impacts on the side of the head cause vibrations in a structure connected to the corpus callosum, potentially leading to concussion symptoms. Magnetic resonance imaging scans revealed possible damage to the corpus callosum in athletes with concussions.
A new study published in Scientific Reports found that brain areas responsible for movement and sensation alter their functional communication after a limb amputation. Researchers discovered that sensitive and motor areas of the brain exhibited abnormal patterns of communication among hemispheres, even in patients without phantom pain.
A new study found that repetitive subconcussive head impacts in youth football can alter the corpus callosum, a critical band of nerve fibers connecting the two halves of the brain. This change may lead to greater risk of cognitive and motor problems in these young athletes.
Researchers found that concussions occur when a deep area of the brain shakes rapidly and intensely, straining surrounding tissues. The study's findings suggest a complex relationship between head impacts and brain motion, highlighting the need for further research to improve diagnosis, treatment, and prevention of concussions.
A study by Mehmet Kurt from Stevens Institute of Technology found that concussions occur when deep white matter regions of the brain, particularly the corpus callosum, shake more rapidly and intensely than surrounding areas. This understanding could lead to better helmet designs and real-time diagnostic tools for athletes.
A study published in Schizophrenia Research found a positive association between corpus callosum integrity and musical aptitude, while reduced integrity was linked to hallucination proneness. Researchers suggest that musical training could potentially counteract an individual's predisposition to hallucinations.
Alfonso Apicella, a UTSA biologist, is exploring the corpus callosum's role in auditory signals and its connection to neurological disorders like schizophrenia and autism. His research aims to better understand how brain hemispheres communicate and potentially develop new treatments.
A study published in Cell Reports reveals that astroglial cells play a crucial role in forming the corpus callosum, a bridge-like structure connecting the two hemispheres of the brain. Without this cellular support, callosal agenesis occurs, affecting 1 in 4,000 people and leading to developmental disorders.
Researchers have linked schizophrenia symptoms to specific brain features using magnetic resonance imaging (MRI). The study identified distinctive subgroups among patients with different symptoms. Analyzing the brain's anatomy may help develop more precise treatments for individual patients.
Research published in Molecular Autism found that male toddlers with autism have distinct brain structure changes compared to females, suggesting separate evaluation and early developmental markers. Additionally, studies suggest a 'female protective effect' through sex differences in genes and prenatal hormones.
Scientists have identified two alternative pathways that compensate for the lack of corpus callosum, enabling communication between brain hemispheres. These pathways are found to be functional and play a crucial role in tactile recognition abilities, similar to those observed in individuals with normal corpus callosum.
A study found that corpus callosum length, thickness of genu and splenium can be used to evaluate premature infant's neurological development. Monitoring corpus callosum development may predict future abnormal neurobehavioral development.
Research reveals Einstein's corpus callosum had more extensive connections compared to younger and older control groups, indicating potential contributions to his intelligence.
Scientists have created a detailed map of the global connections within the brains of individuals with agenesis of the corpus callosum, a genetic cause of autism. The study reveals abnormal brain connectivity patterns and network topology, potentially leading to new imaging biomarkers for diagnosis and management.
Research reveals that specific fibre tracts in the corpus callosum are linked to individual differences in perceived visual motion. The connection affects how people perceive horizontal and vertical motion, with some individuals better at integrating information from both hemispheres.
As we age, breakdowns in brain connections lead to slower reactivity and confusion during one-sided motor movements. Researchers found that older adults' brains communicate more with each other while at rest, hindering brain function.
A study published in Archives of Sexual Behavior found that the brains of gay and straight men differ in terms of brain structure. Gay men tend to have a larger corpus callosum, a region responsible for communication between the two hemispheres of the brain.
Research in capuchin monkeys reveals a connection between sex, handedness, and brain structure. The study found that male monkeys have a smaller corpus callosum than females, while right-handed individuals have a smaller relative size of the corpus callosum than left-handed individuals. This pattern mirrors findings in humans.
The study found that psychopaths have abnormal wiring in the hippocampus and corpus callosum, leading to impulsiveness, lack of emotions, and social disconnectedness. This suggests a neuro-developmental root for psychopathy, with faulty brain development causing structural abnormalities.
Researchers found that skills learned with the dominant arm generalize to the non-dominant arm, but only in extrinsic coordinates, and do not rely on inter-hemispheric communication via the corpus callosum. This challenges current models of brain learning and motor control.
A study published in the Journal of Comparative Neurology found that moderate fetal alcohol exposure can cause the corpus callosum to be larger than normal, contradicting previous research. This could have significant implications for our understanding of fetal alcohol syndrome and its effects on brain development.
