Brain waves could help predict how we respond to general anesthetics

The complex pattern of ‘chatter’ between different areas of an individual’s brain while they are awake could help doctors better track and even predict their response to general anesthesia — and better identify the amount of anesthetic necessary — ac…

Trio of autism-linked molecules orchestrate neuron connections

Researchers have revealed how three proteins work in concert to wire up a specific area of the developing brain that is responsible for processing visual information. The findings may also lend insight into brain disorders including autism, depression …

Remembering to the future: Researchers shed new light on how our memories guide attention

A team of researchers has discovered that differences in the types of memories we have influence the nature of our future encounters. Their findings show how distinct parts of the brain, underlying different kinds of memories, also influence our attent…

‘Bursting’ cells gain the brain’s attention for life-or-death decisions

Using optogenetics and other technology, researchers have for the first time precisely manipulated the bursting activity of cells in the brain’s thalamus, tying the alerting behavior to the sense of touch.

Scientists get mice to pay attention by manipulating neurons in brain

Researchers have identified for the first time a cell type in the brain of mice that is integral to attention. By manipulating the activity of this cell type, the scientists were able to enhance attention in mice. The results add to the understanding o…

Brain waves may be spread by weak electrical field

Researchers may have found a new way information is communicated throughout the brain. Their discovery could lead to identifying possible new targets to investigate brain waves associated with memory and epilepsy and better understand healthy physiology.

New tool may help predict patients’ motor function recovery after stroke

Graph theoretical analysis is proving to be helpful in understanding complex networks in the brain. Investigators used a graph theoretical approach in examining the changes in the configuration of the two hemispheres of the brain in 12 patients after s…

Students’ cognitive functioning improves when using standing desks, new study indicates

Do students think best when on their feet? New findings provide the first evidence of neurocognitive benefits of stand-height desks in classrooms. These findings provide the first evidence of neurocognitive benefits of stand-height desks in classrooms,…

Genes may contribute to making some nations happier than others

The citizens of nations that rate themselves happiest display a specific genetic feature: their DNA is more likely to contain a specific allele involved in sensory pleasure and pain reduction, say researchers. They weighed up genetic and various extern…

Why fish intake by pregnant women improves the growth of a child’s brain

An explanation for the correlation between eating fish during pregnancy, and the health of the baby’s brain, has been uncovered by a group of researchers. Dietary lipid contains fatty acids such as omega-6 and omega-3, which are essential nutrients for…
