Researchers reduced the power requirements of neural interfaces while improving their accuracy by tuning into a subset of brain waves.
A worldwide scientific collaboration has produced the first genetic map of the cerebral cortex. The map identifies more than 300 genetic variants that influence cortical structure and play roles in psychiatric disorders.
Efficient connection pathways across the entire brain provide a neural network that supports general cognitive function and ability. Higher fractional anisotropy is associated with higher IQ.
Researchers have created the first genetic map of the cerebral cortex, which identifies over 300 genetic variants that influence the structure of the brain region.

Combining neuroimaging data with artificial intelligence, researchers have identified two distinct neuroanatomical subtypes of schizophrenia. The first, more typical subtype is associated with a lower widespread volume of gray matter compared to healthy controls. In the second subtype, gray matter volume is largely similar to healthy brains.
Heart insufficiency has a negative impact on gray matter in the brain. Weak heart function was linked to decreased gray matter in areas of the brain associated with memory and learning, including the hippocampus and parietal medial cortex. This may increase the risk of Alzheimer's disease.
Cardiorespiratory exercise improves gray matter volume in areas of the brain associated with age-related cognitive decline. The findings add weight to the previous studies which link physical activity to neuroprotection against age-related cognitive decline.
Teens with a particular pattern of brain development have an increased frequency of drunkenness, a new study reports. Decreased gray matter density in the frontal and temporal brain regions was associated with an increased risk of teenage over-drinking.
Telomere lengthening resulted in structural changes in the brain, including cortical thickening. By contrast, telomere shortening is associated with gray matter reduction, specifically in the precuneus.
Neuroimaging reveals 'successful' psychopaths (those who can control their antisocial tendencies) have greater levels of gray matter density between the left and right ventromedial prefrontal cortex. This area of the brain is implicated in self-regulatory processes, including reactive emotions.
Neuroimaging study reveals teens with more gray matter in the caudate nucleus and left cerebellum were at increased risk of problem alcohol use over time. The findings reinforce the idea that brain structure differences may contribute to both psychiatric and substance use disorders.
