Scientists Inject Human Brain Cells Into Mice, Make Them Smarter

Scientists Inject Human Brain Cells Into Mice, Make Them Smarter | Longevity science | Scoop.it

In an experiment that might seem like something only a mad scientist would conjure, researchers injected human brain cells into the brains of mice to see how it would affect the way the mice thought. It did: the mice got smarter.

 

But the cognition boosting cells weren’t neurons...

Toxic interaction in neurons that leads to dementia and ALS | KurzweilAI

Toxic interaction in neurons that leads to dementia and ALS | KurzweilAI | Longevity science | Scoop.it
Researchers at Mayo Clinic in Florida have uncovered a toxic cellular process by which a protein that maintains the health of neurons becomes deficient and can lead to dementia.

The findings shed new light on the link between culprits implicated in two devastating neurological diseases: Alzheimer’s disease and amyotrophic lateral sclerosis, also known as Lou Gehrig’s disease, which afflicts physicist Stephen Hawking.

There is no cure for frontotemporal dementia, a disorder that affects personality, behavior and language and is second only to Alzheimer’s disease as the most common form of early-onset dementia.

Parkinson’s breakthrough could slow disease progression | KurzweilAI

Parkinson’s breakthrough could slow disease progression | KurzweilAI | Longevity science | Scoop.it

Northwestern University scientists have developed a new family of compounds that could slow the progression of Parkinson’s disease.

 

Parkinson’s, the second most common neurodegenerative disease, is caused by the death of dopamine neurons, resulting in tremors, rigidity and difficulty moving. Current treatments target the symptoms but do not slow the progression of the disease.

 

The compounds work by blocking calcium. The compounds target and shut a relatively rare membrane protein that allows calcium to flood into dopamine neurons.
