Researchers found that the brain's auditory cortex responds strongly to positive human sounds coming from the left, but not from the right or front. This bias may have an evolutionary advantage, as it could help detect potential threats or predators.
Researchers found that individuals who underwent hemispherectomy surgery at a young age can still recognize differences between pairs of words or faces with remarkable accuracy. The study, published in PNAS, sheds light on brain plasticity and its limitations.
A study found that infant brains can reorganize language abilities to the right side of the brain after a stroke in the left hemisphere. Participants showed consistent pattern of language activation on the right hemisphere, regardless of damage extent.
A large study comparing the brains of left-handers and right-handers found significant differences in brain asymmetry across ten regions. The research also discovered a link between genetic influences on handedness and brain asymmetries in language-related regions.
Learning a new language alters how the brain divides labor between hemispheres. Comprehension becomes more specialized in one hemisphere, while production remains linked to the left hemisphere.
Researchers at HSE University found that the brain comprehends words placed on the right side of a screen more quickly. The total amount of presented information affects speed and accuracy of word processing.
Research in four-year-old children found that the right hemisphere can take over language functions when the left hemisphere is damaged early in development. This flexibility of the brain offers insight into typical language development and recovery from injury.
Biopsychologists demonstrate that subtle timing differences in the right hemisphere allow it to control specific functions, while the left hemisphere delays its activity. The study reveals a sophisticated mechanism underlying hemispheric dominance.
Researchers have found that the left hemisphere of the brain processes auditory speech information more rapidly than the right, thanks to a higher number of densely packed neurites in planum temporale. This microstructure is crucial for linguistic superiority.
A study by Brown University researchers found that one brain hemisphere remains more awake than the other during deep sleep on the first night in a new place. This 'first-night effect' is thought to be an evolutionary adaptation to protect against potential danger.
Researchers investigate brain structure involved in imitation after stroke or brain injury, discovering the importance of similarity between observed action and produced movement. Lesions in the left hemisphere affect anatomical match, while those in the right hemisphere impact spatial translation.
Researchers found that increased grey matter volume in the right hemisphere relates to better-than-expected speech abilities in stroke survivors. The study suggests a new direction in treatment for post-stroke language disorders.
Researchers discovered that whistled Turkish, a unique form of communication, alters language asymmetries in the brain. Studies show that both hemispheres are equally involved in processing whistled Turkish, contradicting the notion that language is predominantly left-brained.
Researchers found that the right hemisphere of the brain is more integrated and communicative than the left hemisphere during rest, regardless of hand dominance. This study may help explain why power naps benefit focus and mental clarity.
Researchers found that the left hemisphere specializes in rapidly changing sounds, while the right hemisphere prefers slowly changing sounds. This study may lead to new strategies for treating speech loss after a stroke and improving speech recognition in children with dyslexia.
A new study by USC researchers reveals that creativity requires both hemispheres of the brain, with the left hemisphere playing a crucial supporting role. The study found that visual creative tasks lit up the left hemisphere more than non-creative tasks, indicating its potential importance in creative thinking.
A new study reveals a consistent pattern of brain injury to the frontal lobe and right hemisphere causes delusions. The overcompensation of the left hemisphere leads to the creation of false narratives that cannot be edited, resulting in pathologic beliefs.
Researchers found that language capacity 'evens out' with age, with older adults using more of both hemispheres relative to language skills. The study suggests improvements in linguistic skills and maturation of the central nervous system contribute to increased hemisphere dominance in childhood.
A study has identified a significant difference in brain tissue structure between individuals with persistent developmental stuttering and those with normal speech. The abnormality may develop during early language and speech acquisition, explaining how disturbed signal transmission affects speech production.
