Researchers have shown in mice that brain cells known as astrocytes are required for a signaling chemical called norepinephrine to modify brain activity, changing the textbook understanding that ...

For over a decade, neuroscientists have been trying to figure out how neurogenesis (the birth of new neurons) and neuroplasticity (the malleability of neural circuits) work together to reshape how we ...

A study by Dorothy P. Schafer, Ph.D., and Travis E. Faust, Ph.D., at UMass Chan Medical School, explains how two different cell types in the brain—astrocytes and microglia—communicate in response to ...

Scientists have long known that the brain's visual system isn't fully hardwired from the start—it becomes refined by what babies see—but the authors of a new MIT study still weren't prepared for the ...

Science X is a network of high quality websites with most complete and comprehensive daily coverage of the full sweep of science, technology, and medicine news ...

The human brain contains nearly 86 billion neurons, constantly exchanging messages like an immense social media network, but neurons do not work alone – glial cells, neurotransmitters, receptors, and ...

What do you anticipate when you are about to go for a 20-minute walk, but struggle with chronic pain in your back, legs, or feet? You probably dread the inevitable ache radiating from your back or the ...

A single dose of the psychedelic compound psilocybin could be enough to remodel connections of specific brain networks, which may explain how the drug helps to treat some mental health conditions.

The team found that a brain chemical associated with alertness, attention and learning alters brain connectivity and function not by acting directly on neurons, the cells known for their quick ...
