Regeneration is the ability of the stem cells to divide and produce new neurons.
Plasticity is the ability of the newborn neurons to make connections with existing neurons in the brain and integrate into their surrounding cellular environment. Though other studies have shown that new neurons are born under other conditions, this is the first study to show that new brain cells are born following stroke. It is not known whether there are new neurons born in the brains of humans following stroke. We certainly think there would be. If you lose this region of the brain, you re unable to remember new sights, sounds and other experiences.
