Insulin in the brain influences dopamins levels

In the human brain, the hormone insulin also acts on the most important neurotransmitter for the reward system, dopamine. Insulin lowers the dopamine level in a specific region of the brain (striatum) that regulates reward processes and cognitive funct…

Quantum brain sensors could be crucial in spotting dementia after scientists find they can track brain waves

New highly sensitive quantum sensors for the brain may in the future be able to identify brain diseases such as dementia, ALS and Parkinson’s, by spotting a slowing in the speed at which signals travel across the brain.

How do we know we’re tired?

Why do we need sleep? New research takes a step towards solving this mystery by discovering a mechanism of sleep in zebrafish, with some supporting evidence in mice.

‘Deepfaking the mind’ could improve brain-computer interfaces for people with disabilities

Researchers are using generative adversarial networks (GANs) — technology best known for creating deepfake videos and photorealistic human faces — to improve brain-computer interfaces for people with disabilities. The team successfully taught an AI t…

Chronic stress and depression boost this brain receptor; a new study maps out how to block it

Eliminating GPR158 activity in stressed mice made them resistant to depression and anxiety. A new study in the journal Science reveals the unusual brain receptor’s structure, and possible ways a medication might reduce its sway.

The brain uses bodily signals to regulate fear

Fear is essential for survival, but must be well regulated to avoid harmful behaviors such as panic attacks or exaggerated risk taking. Scientists have now demonstrated in mice that the brain relies on the body’s feedback to regulate fear. The brain’s …
