What unique processes conspire to create a healthy, functional human brain? How can we be so genetically similar to, say, chimpanzees, and yet be light-years more sophisticated cognitively and ...

For the first time, clumps of human cells called organoids were fully integrated with the brains of rats—and influenced their behavior.

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 ...

Like the seeds of a forest, a few cells in embryos eventually sprout into an ecosystem of brain cells. Neurons get the most recognition for their computing power. But a host of other cells provides ...

Whether or not we grow new brain cells as adults has been the subject of an ongoing and often contentious debate. Now, evidence suggests that we can. This could help answer one of neuroscience’s most ...

In experiments with mice, Johns Hopkins Medicine scientists report new evidence that precursors of myelin-producing cells—one ...
