A recent study by researchers at the University of California, Riverside, found that a specific brain region known as the caudate nucleus is strongly linked to physical strength in older adults. The discovery could help detect and prevent frailty before it begins.
Research finds infants with sensorineural hearing loss lack normal left-hemisphere language specialization. Early auditory stimulation and language exposure can help preserve brain development.
A new study reveals that brain lateralization is essential for the emergence of left-to-right spatial-numerical associations in newborn chicks. Strongly lateralized chicks showed a clear preference for selecting food from the left, while weakly lateralized chicks had no consistent directional preference.
A research team analyzed YouTube videos of sleeping cats to find that two thirds sleep on their left side. This bias is thought to be an evolutionary strategy, favoring the use of the right hemisphere of the brain for spatial awareness and threat processing after waking.
A new technique using focused sound waves and microbubbles has shown great promise in treating debilitating brain lesions called cerebral cavernous malformations. The approach has halted the growth of lesions almost entirely, offering a potential paradigm shift in treatment.
Research by MIT neuroscientists reveals that the brain separates its processing of spatial information to maintain cognitive advantage, yet seamlessly blends it with other features. The study also explores how the brain 'hands off' visual information between hemispheres.
Research reveals that brain hemispheres synchronize gamma waves to integrate auditory information, enabling us to hear a unified speech sound. Electric stimulation disrupts this synchronization, impairing the integration process and potentially leading to tinnitus.
A study published in Science Advances reveals a genetic program essential for 3D vision and motor coordination in mice. The discovery sheds light on the regulation of the Wnt signaling pathway by Zic2, which is crucial for bilateralism and has implications for understanding pathologies such as spina bifida.
Researchers found that right-handed baseball players who bat left-handed have an advantage over those who bat and throw left-handed. This study, reanalyzing data from 1871 to 2016, suggests that throwing right-handed but batting left improves a player's likelihood of becoming a top hitter in Major League.
Research by Anglia Ruskin University shows that right-handed baseball players who bat left but throw right-handed have a surprising advantage in career success and hitting performance. This biomechanical advantage provides a longer lever to hit the ball, increasing their chances of becoming top hitters.
Scientists at UC San Diego have discovered how brain blood vessels dynamically regulate oxygen levels across large distances, shedding light on the mechanisms behind resting-state connectivity. This breakthrough has significant implications for human health and medicine, including the development of higher resolution imaging methods.
A study found that more left-handed men are born during November, December, and January, with 10.5% of left-handed men born during this period. The researchers suggest a hormonal cause, possibly related to the relative darkness during these months, which delays the maturation of the left brain hemisphere during embryonic development.
Scientists study the impact of asymmetrical light input on cerebral hemispheric specialization and interhemispheric cooperation in bird embryos. The results show that information exchange is impaired without light-stimulation, which may help understand developmental disorders like ADHD or autism.
A study published in Human Brain Mapping found that damaged corpus callosum and impaired interhemispheric communication hinder motor skill recovery in stroke patients. The researchers used imaging methods to show increased activity on both sides of the brain and lower tapping speed in stroke patients compared to healthy controls.
