Orienting and executive inhibition, two key brain functions associated with attending to new information and focusing on important aspects of a situation, can improve in older individuals. These functions underlie aspects of cognition, including memory and decision making, and even navigation, math, and language.
The brain processes motor commands, not just through fine muscle contractions, but also via higher-level motor areas that provide a blueprint for performing more complex motor functions, such as grasping, no matter if the toes or fingers are used.
Unlike adults, infants and young children use both hemispheres of their brain to process language.
Females who attend school for longer have better memory ability in old age, a new study reports. For each year of education, memory gains were, on average, five times greater for women than the losses experienced due to each year of aging.
Combining medications used to treat neurological disorders, such as epilepsy and migraines, with blood pressure medications reversed some aspects of breast cancer in mice at high risk of developing the disease due to the high-fat diets fed to their mothers during pregnancy.
Crashes in visual processing occur when neurons processing one image are tasked with processing another too quickly. This results in either one or both images being unable to reach our conscious awareness.
New findings dispute the popular cerebellar deficit hypothesis of dyslexia. Researchers report the cerebellum is not engaged during reading in typical readers and does not differ in children with dyslexia.
Polychlorinated biphenyls (PCBs), chemicals commonly used during the 20th century as flame retardants and in industrial products, disrupt the performance of astrocytes, leading to impaired function. Environmental exposure to PCBs could contribute to a range of neurodegenerative diseases.
Researchers debate the growing use of tES to enhance creativity, concluding there is a potential value in brain stimulation. However, researchers say, the use of tES raises a number of neuroethical, legal and social issues that must be addressed.
According to researchers, following a perinatal stroke that damages the language area in the left hemisphere, the brain remaps to use the right hemisphere for language.
A new study reveals language is learned in brain systems that predate humans.
