Scientists in Japan have created powerful new vitamin K-based compounds that may help the brain regenerate lost neurons — a breakthrough that could one day change how diseases like Alzheimer’s and Parkinson’s are treated.…

It’s further proof that even fairly complex neural processes are not the same as consciousness.

Researchers at Princeton University have created a new device that combines living brain cells with electronics to recognise simple patterns.

Organ intrinsic nervous systems (OINSs) are critical components of the body–brain axis and coordinate visceral organ function with systemic physiological control1–7.…

Dopamine seems to be ubiquitous. It is invoked to explain a wide range of phenomena—by the media, on podcasts, and even by people in everyday conversations. It has been labelled the brain’s chemica…

Scientists have uncovered a hidden “stop-scratching” signal in the nervous system that tells your brain when enough scratching is enough. The discovery centers on a molecule called TRPV4, which acts like part of an internal braking system for itch relief.…

DNA damage from inflammation outpaces the cells’ ability to self-repair. The finding, in human brain cells and mice, could point to new MS treatments.

Early in life, neural networks in the brain's memory center are highly connected, and they are only later refined into precise systems, a mouse study finds.

The brain’s memory center may begin life more like a crowded web than an empty canvas. Researchers discovered that early neural networks in the hippocampus are dense and seemingly random, then become more organized by shedding connections over time.…

According to a new study, imagination may have more to do with the brain activity it silences than the activity it creates.

Scientists have finally cracked one of the biggest mysteries in the senses: how smell is organized. By mapping millions of neurons in mice, researchers discovered that smell receptors in the nose aren’t random at all—they’re arranged in neat, overlapping…

A new map shows how smell receptors in the mouse nose are precisely organized into tight bands based on type.

A startup is experimenting with data centers powered by lab-grown human neurons, testing whether living cells can offer a more efficient alternative to traditional computing.

Researchers find that neurons in the visual cortex of the brain can flexibly extract different kinds of information from the same image, upending a fundamental paradigm in neuroscience

From Live Science: Scientists invent artificial neurons that 'talk' to real brain cells, paving way to better brain implants

Webs of star-shaped cells called astrocytes connect distant parts of the brain, allowing long-distance exchange of molecules. Webs of star-shaped cells called astrocytes connect distant parts of the brain, allowing long-distance exchange of molecules.

While past research has hinted at an overlap in relevant brain regions, the new work drills down to the cellular level. The discovery could help improve treatments for memory disorders, such as dementia, and certain psychiatric conditions, like…
