Smooth movements are achieved by the stable basal ganglia activity

Researchers have applied a chemogenetic tool in macaque monkeys and suppressed the subthalamic nucleus, a part of the basal ganglia circuitry. The chemogenetic suppression induced unstable movements. In the output nucleus of the basal ganglia, the inte…

Scientists discover mechanism behind chemically induced suppression of fearful memories

Fearful events negatively impact the brain. For instance, war veterans often go through post-traumatic stress disorder months after the cessation of the triggering event. Now, the precise mechanism of suppression of such fearful memories has been uncov…

An ocean in your brain: Interacting brain waves key to how we process information

For years, the brain has been thought of as a biological computer that processes information through traditional circuits, whereby data zips straight from one cell to another. While that model is still accurate, a new study shows that there’s also a se…

Some autism spectrum disorder symptoms linked to astrocytes

Abnormalities in a type of brain cell called astrocytes may play a pivotal role in causing some behavioral symptoms of autism spectrum disorders, according to a preclinical study.

Fungal meningitis spreads by blocking and bursting blood vessels

New research has revealed how fungus blocks and bursts blood vessels in the brain, helping scientists better understand how meningitis starts.

Study reveals set of brain regions that control complex sequences of movement

In a novel set of experiments with mice trained to do a sequence of movements and ‘change course’ at the spur of the moment, scientists report they have identified areas of the animals’ brains that interact to control the ability to perform complex, se…

Circuit that focuses attention brings in wide array of inputs

With a comprehensive map of the wiring, researchers can now discern what information flows into the circuit to enable a key brain function.

For neurons, where they begin isn’t necessarily where they end

Scientists describe novel methods for inferring the movement of human brain cells during fetal development by studying healthy adult individuals who have recently passed away from natural causes.

Whole-brain preclinical study illuminates how epileptic seizures originate

New evidence from a zebrafish model of epilepsy may help resolve a debate into how seizures originate, according to investigators. The findings may also be useful in the discovery and development of future epilepsy drugs.

How do our eyes stay focused on what we reach for?

Keeping our eyes focused on what we reach for, whether it be an item at the grocery store or a ground ball on the baseball field, may appear seamless, but, in fact, is due to a complex neurological process involving intricate timing and coordination. R…
