A new imaging technique opens a path toward long-term study of blood vessels in aging brains and could help predict neurodegenerative diseases decades before symptoms begin.
Many of our body’s most important functions occur without our conscious knowledge, such as digestion, heartbeat, and breathing. These vital functions depend on the signals generated by the “interocept...
The following press release was issued today by the Broad Institute of MIT and Harvard.
Our brains are charged with the task of directing most of the processes needed for our bodies to function. As such, they consume roughly 20% of our body’s metabolic energy, even while we’re resting.
Alzheimer’s risk gene undermines insulation of brain’s “wiring”（图）

It’s well-known that carrying one copy of the APOE4 gene variant increases one’s risk for Alzheimer’s disease threefold and two copies about tenfold, but the fundamental reasons why, and what can be d...
What a long, strange trip it’s been for psychedelic drugs. From their use in ancient indigenous ceremonies, to their often-caricatured association with the 1960s counterculture, to their recent reemer...
This is a coming-of-age story — involving your brain.
A new study by scientists at The Picower Institute for Learning and Memory at MIT provides the most comprehensive and rigorous evidence yet that the mammalian brain stores a single memory across a wid...
What’s the link between social life and brain structure? Researchers from the University of Pennsylvania, the Stem Cell and Brain Research Institute at Inserm, and elsewhere are now one step closer to...
近日，暨南大学粤港澳中枢神经再生研究院周立兵和曲宜波团队在国际著名期刊Brain（IF=13.501）发表题为“Inactivating Celsr2 promotes motor axon fasciculation and regeneration in mouse and human”研究论文。本研究首次报道神经发育相关基因Celsr2调控脊髓运动神经元轴突再生，其作用在小鼠和人神经组织中具...
While neurons and glial cells are by far the most numerous cells in the brain, many other types of cells play important roles. Among those are cerebrovascular cells, which form the blood vessels that ...
The human brain uses more energy than any other organ in the body, requiring as much as 20% of the body’s total energy. While this may sound like a lot, the amount of energy would be even higher if th...
New poo, new you? Fecal transplants reverse signs of brain aging in mice

As you age, your brain slows down. You may forget where you left your glasses or have trouble picking up a new skill. Now there’s hope from rodent experiments that some of these declines could be reve...
Every time we reach for a cup, our brains must assess our hands’ current position in relation to the mug and then command muscles to make the proper adjustments to successfully grab the handle.
