Using a fluorescent probe that lights up when brain cells are electrically active, MIT and Boston University researchers have shown that they can image the activity of many neurons at once, in the brains of mice.

To understand our brains, scientists need to know their components. This theme underlies a growing effort in neuroscience to define the different building blocks of the brain—its cells.

Circulation and cellular activity were restored in a pig's brain four hours after its death, a finding that challenges long-held assumptions about the timing and irreversible nature of the cessation of some brain functions ...

New research shows how the depth of sleep can impact our brain's ability to efficiently wash away waste and toxic proteins. Because sleep often becomes increasingly lighter and more disrupted as we become older, the study ...

(Medical Xpress)—With thousands of basic and clinical neuroscience studies carried out over the past 15 years, the Default Mode Network (DMN) – a network of highly co-correlated interacting regions whose activity is very ...
Physicians and biomedical engineers from Johns Hopkins report what they believe is the first successful effort to wiggle fingers individually and independently of each other using a mind-controlled artificial "arm" to control ...

(Phys.org)—In vivo neural electrical activity is the essence of nervous system function, controlling sensory modalities, emotion, memory, behavior, and basic survival functions. Therefore, to study neurons in the laboratory ...
Researchers at NYU Langone Medical Center have found that navigational brain cells that help sense direction are as electrically active during deep sleep as they are during wake time—and have visual and vestibular cues ...

Anesthesia makes otherwise painful procedures possible by derailing a conscious brain, rendering it incapable of sensing or responding to a surgeon's knife. But little research exists on what happens when the drugs wear off.
