Developing brains constantly sprout new neuronal connections called synapses as they learn and remember. Important connections—the ones that are repeatedly introduced, such as how to avoid danger—are nurtured and reinforced, ...

Studying mice, scientists at Johns Hopkins have fortified evidence that a key purpose of sleep is to recalibrate the brain cells responsible for learning and memory so the animals can "solidify" lessons learned and use them ...

Exactly how memories are stored and accessed in the brain is unclear. Neuroscientists, however, do know that a primitive structure buried in the center of the brain, called the hippocampus, is a pivotal region of memory formation. ...

Microglia are primary immune cells that safeguard the mammalian brain, partly by devouring or 'phagocytosing' pathogens and toxic debris. Recent genetic studies have consistently highlighted the role of microglia in the development ...
