Stroke produces dysfunctional brain cells

Mice produce new neurons in the hippocampus following a stroke that fail to develop properly, finds new research published in JNeurosci. Intervening in the production of these cells may help to mitigate stroke-induced memory impairments.

Stroke has long been known to increase adult neurogenesis. Despite the proliferation of new cells in a brain region critical for memory, previous stroke research in animals shows this process is accompanied by deficits on tasks that depend on the hippocampus. You could read more here.
