Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue ...

Both for research and medical purposes, researchers have spent decades pushing the limits of microscopy to produce ever deeper and sharper images of brain activity, not only in the cortex but also in ...

The next time you reach for a memory or make a quick choice, a storm of tiny signals races through your brain. Scientists can ...

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 ...

A cubic millimeter of brain tissue may not sound like much. But considering that tiny square contains 57,000 cells, 230 millimeters of blood vessels, and 150 million synapses, all amounting to 1,400 ...

Researchers have discovered a mechanism that creates memories while reducing metabolic cost, even during sleep. This efficient memory occurs in a part of the brain that is crucial for learning and ...

Most of the time, you assume your brain is either “on” or “off,” awake or asleep. A new study shows something far more ...

The human brain is often compared to a computer, but the latest wave of research shows it is closer to a self-building city, ...

UCLA Health researchers have discovered a mechanism that creates memories while reducing metabolic cost, even during sleep. This efficient memory occurs in a part of the brain that is crucial for ...
