With the aid of a 3D printer, researchers at Uppsala University have succeeded in creating a model that resembles human nerve tissue. The model, which can be cultured from the patient's own cells, ...

A tiny circuit, printed from ink made of atom-thin crystals, just fired electrical pulses that a living brain cell recognized ...

All cells, whether big or small, short or long, rely on proteins to function properly. In most cells, transporting these proteins is relatively simple. Neurons in the brain, however, face a ...

Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this ...

Nerve cells are not just nerve cells. Depending on how finely we distinguish, there are several hundred to several thousand different types of nerve cell in the human brain according to the latest ...

Scientists created a model of the human pain pathway in a dish by connecting four separate brain organoids. The feat should help them understand sensory disorders like those affecting pain perception.

Obesity is a global health problem that affects many people. In recent years, very promising anti-obesity drugs have been developed. Despite these successes, there are patients who do not respond to ...

Scientists at the University of Gothenburg have pinpointed a group of nerve cells in the brain stem that appear to be responsible for semaglutide’s appetite- and weight-controlling powers—without ...
