Neurons spoil your appetite

A brain circuit inhibits food intake during nausea.

New research shows ‘profound’ link between dietary choices and brain health

New research has highlighted the profound link between dietary choices and brain health.

Chemical tool illuminates pathways used by dopamine, opioids and other neuronal signals

Researchers have developed a new tool to better understand how chemicals like dopamine and epinephrine interact with neurons.

Innovative microscopy demystifies metabolism of Alzheimer’s

Using state-of-the-art microscopy techniques, researchers have shed new light on the underlying mechanisms driving Alzheimer’s disease.

Social media affects people’s views on mental illness

Even subtle differences in the wording of social media messages may be enough to sway young people’s beliefs about depression and anxiety and their treatment.

In the brain, bursts of beta rhythms implement cognitive control

Bursts of brain rhythms with ‘beta’ frequencies control where and when neurons in the cortex process sensory information and plan responses. Studying these bursts would improve understanding of cognition and clinical disorders, researchers argue in a n…

Exploring brain synchronization patterns during social interactions

Social interactions synchronize brain activity within individuals and between individuals. In a new study, researchers compared brain synchronization between pairs of people with relatively strong social ties (acquaintance pairs) and pairs with almost …

Glial hyper-drive for triggering epileptic seizures

When epileptic patients suffer seizures, their brain is undergoing repetitive and excessive neuronal firing. But what triggers this has stumped scientists for years. Now, researchers have used fluorescence calcium sensors to track astrocytes’ role in e…

When thoughts flow in one direction

Contrary to previous assumptions, nerve cells in the human neocortex are wired differently than in mice. The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops. This increases the efficiency and ca…

Perfect balance: How the brain fine-tunes its sensitivity

A sensitive perception of the environment is crucial for guiding our behavior. However, an overly sensitive response of the brain’s neural circuits to stimuli can lead to neurodevelopmental disorders such as epilepsy. Researchers now report how neurona…
