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 ...

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 ...

Hormone levels fluctuate like the tides, ebbing and flowing according to carefully orchestrated cycles. These hormones not only influence the body, but can cross into the brain and shape the behavior ...

Brain cells are constantly swallowing material from the fluid that surrounds them—signaling molecules, nutrients, even pieces of their own surfaces—in a process known as endocytosis that is essential ...

A project at the University of Colorado Boulder (CU Boulder) has developed a new way to image neural activity in live animals. Described in Biomedical Optics Express, the device is a miniaturized ...

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 ...

Researchers from Stanford Medicine have found a new way to accelerate the growth of neurons, or nerve cells, according to a study published in Nature on Oct. 2. Neurons are vital to memory, but they ...

The same neuron can tell fruit flies to walk toward the smell of rotting fruit and speed up, according to new research from Yale scientists. Neurobiologists once believed that each neuron held a ...

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, ...
