I still vividly remember the first time we observed neurons responding not to audible sound, but to concentrated, precisely calibrated ultrasonic pulses. On the screen in front of us, calcium signals ...

A thin strip of flexible film, printed with layers of graphene and molybdenum disulfide ink, fired electrical spikes into a slice of living mouse brain tissue and got an answer back. The neurons in ...

Researchers have created a protein that can detect the faint chemical signals neurons receive from other brain cells. By tracking glutamate in real time, scientists can finally see how neurons process ...

The findings point to the brain's own communication machinery unknowingly contributing to the spread of the disease.

The human brain contains nearly 86 billion neurons, constantly exchanging messages like an immense social media network, but neurons do not work alone – glial cells, neurotransmitters, receptors, and ...

From Santiago Ramón y Cajal’s hand came branches and whorls, spines and webs. Now-famous drawings by the neuroanatomist in the late 19th and early 20th centuries showed, for the first time, the ...

Northwestern University engineers printed artificial neurons that don't just imitate the brain - they talk to it. In a new study, the Northwestern team developed flexible, low-cost devices that ...
