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

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 ...

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

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 ...

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 ...

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 ...

Commensurate with the degree of dopamine connectivity, Ppp1r1b cells had more receptors than Rspo2 neurons. Dopamine does a lot of things, so the next question was whether its activity in the ...
