Calming Overexcited Neurons May Protect Brain After Stroke

Neuroscientists believed that, in the aftermath of a stroke, calming overexcited neurons might prevent them from releasing a toxic molecule that can kill neurons already damaged by lack of oxygen. This idea was supported by studies in cells and animals, but it lost favor in the early 2000s after numerous clinical trials failed to improve outcomes for stroke patients. But a fresh approach has yielded evidence that the idea may have been discarded too hastily. Read more…
