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 ...

In the late 1800s, Spanish neuroscientist Santiago Ramón y Cajal drew hundreds of images of neurons. His exquisite work influenced our understanding of what they look like: Cells with a bulbous center ...

A new tool captures data from an unprecedented 1 million neurons simultaneously, painting a much fuller picture of brain dynamics. The mammalian brain is a web of densely interconnected neurons, yet ...

Neuroscientists have unveiled an engineered protein that lets them watch incoming signals wash over neurons in real time, turning what used to be invisible chemical whispers into vivid, trackable ...

Scientists have engineered a protein able to record the incoming chemical signals of brain cells (as opposed to just their ...

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 ...

Study finds ultrathin tubes connecting brain cells that transport Alzheimer's proteins. The network changes months before plaques appear.

Whether reeling from a sudden stroke or buckling under the sustained assault of Alzheimer’s, the brain becomes inflamed, leading to cognitive problems and even death. Scientists have known for many ...

Scientists can finally hear the brain’s quietest messages—unlocking the hidden code behind how neurons think, decide, and ...

In-vivo imaging of the neuronal activity in mouse primary visual cortex. Left, high-resolution neuronal map; middle, high-speed neuronal activity recording captured by the two-photon microscope with ...
