Neural circuits mapped: Now we understand vision better

Researchers have discovered the function of a special group of nerve cells which are found in the eye and which sense visual movement. The findings give us a completely new understanding of how conscious sensory impressions occur in the brain.

When damaged, the adult brain repairs itself by going back to the beginning

When adult brain cells are injured, they revert to an embryonic state, say researchers. In their newly adopted immature state, the cells become capable of re-growing new connections that, under the right conditions, can help to restore lost function.

How expectations influence learning

During learning, the brain is a prediction engine that continually makes theories about our environment and accurately registers whether an assumption is true or not. A team of neuroscientists has shown that expectation during these predictions affects…

Being right-brained or left-brained comes down to molecular switches

Scientists may have solved one of the most puzzling and persistent mysteries in neuroscience: why some people are ‘right-brained’ while others are ‘left-brained.’ The answer lies in how certain genes on each side of the brain are switched ‘on’ and ‘off…

Long spaceflights affect astronaut brain volume

Extended periods in space have long been known to cause vision problems in astronauts. Now a new study suggests that the impact of long-duration space travel is more far-reaching, potentially causing brain volume changes and pituitary gland deformation.

How stress remodels the brain

Research has shown how stress changes the structure of the brain and reveals a potential therapeutic target to the prevent or reverse it.

Novel high-speed microscope captures brain neuroactivities

A research team has successfully recorded the millisecond electrical signals in the neurons of an alert mouse with their super high-speed microscope – two-photon fluorescence microscope. The new technique is minimally invasive to the animal being teste…

Aha! + Aaaah: Creative insight triggers a neural reward signal

A new neuroimaging study points to an answer of what may have driven the evolutionary development of creativity.

Novel role for dopamine that impacts gene expression related to cocaine abuse

Scientists have discovered a new role for the brain chemical dopamine that is independent of classic neurotransmission. The new role appears to be critical to changes in gene expression related to chronic exposure to, or abuse of, cocaine.
