Neuronal plasticity in chronic pain-induced anxiety revealed

Researchers have shown how chronic pain leads to maladaptive anxiety in mice, with implications for treatment of chronic pain-related psychiatric disorders in humans.

Researchers investigate connection between loss of motivation and Alzheimer’s disease progression

Researchers are studying why neuropsychiatric symptoms, such as apathy and irritability, appear in most Alzheimer’s disease patients before the onset of memory loss.

Anesthetic drastically diverts the travels of brain waves

Under propofol general anesthesia very slow frequency traveling waves transform and dominate, redirecting and disrupting the higher frequency traveling waves associated with conscious function.

Gastrointestinal issues linked with anxiety, social withdrawal for kids with autism

A new study found a ‘bi-directional’ relationship between gastrointestinal issues and internalized symptoms in children and adolescents with autism — meaning the symptoms seem to be impacting each other simultaneously. The findings could influence fut…

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…
