Researchers have built a tiny, lightweight microscope that captures neuron activity with unprecedented speed that can be used in freely moving animals. The new tool could give scientists a more ...

It takes just a few milliseconds: A vesicle, only a few nanometers in size and filled with neurotransmitters, approaches a cell membrane, fuses with it, and releases its chemical messengers into the ...

The mysteries of the brain have captivated scientists for more than 100 years, most notably illustrated in the detailed drawings of neuroanatomist Santiago Ramón y Cajal. These drawings and his ...

Researchers developed a tiny, lightweight microscope that captures the electrical spikes of neurons at hundreds of frames per second in awake animals. WASHINGTON — Researchers have built a tiny, ...
