Dangers come but dangers also go and when they do, the brain has an "all-clear" signal that teaches it to extinguish its fear ...

In a pair of small studies designed primarily to test safety, two teams of researchers found that stem cells transplanted ...

In a small study, researchers transplanted stem cells into the brains of 12 Parkinson’s patients, stopping progression and ...

A new study reveals that dopamine release along a specific brain circuit helps extinguish fear by activating reward-related ...

In a first-of-its-kind human trial, researchers transplanted iPS-cell-derived dopaminergic progenitors into patients with ...

The cell loss caused by Parkinson’s results in a lack of dopamine—a key neurotransmitter—in the brain, so many Parkinson’s treatments seek to boost dopamine levels. These include medicines ...

Their symptoms also improved. In both studies, published in the journal Nature, transplanted stem cells began making the chemical messenger dopamine. It is the loss of dopamine-producing neurons that ...

Dangers come but dangers also go and when they do, the brain has an "all-clear" signal that teaches it to extinguish its fear. A new study in mice by ...

To be honest, I hadn’t really thought about it all that much. In my estimation, it didn’t seem to be out of the ordinary — not at all. And for ...

Clinical trials show stem cell therapies for Parkinson's disease are safe, potentially offering more effective treatment with ...
