100-Hour-Long MRI of Human Brain Produces Most Detailed 3D Images Yet

Posted by in categories: biotech/medical, neuroscience

Scientists have produced what looks to be the most detailed magnetic resonance imaging (MRI) scan ever taken of the human brain anatomy, and are sharing their data with the public.

Thanks to an anonymous deceased patient whose brain was donated to science – and a gargantuan 100 hours of scanning with one of the most advanced MRI machines – the world now has an unprecedented view of the structures that make thought itself possible.

In a new study led by neuroimaging scientist Brian L. Edlow from Massachusetts General Hospital, researchers describe how they recorded their ultra-high resolution MRI dataset of the ex vivo specimen, offering a never-before-seen view of the “three-dimensional neuroanatomy of the human brain”.

Scientists Have Discovered a New Stem Cell That Could Heal Brain Damage

Posted by in categories: biotech/medical, neuroscience

A newly discovered type of stem cell could help brains repair themselves from injury or even debilitating diseases like Alzheimer’s, according to the latest research.

Called the “G2 quiescent stem cell”, it’s one of several ‘sleeping’ (or quiescent) stem cells in the brain.

But this one is showing more potential for regeneration than the others have so far. Like other stem cells, it can produce cells of all different types on demand – whatever the body needs.

Elon Musk says his Neuralink startup already has a brain-machine interface working in monkeys

Posted by in categories: computing, Elon Musk, neuroscience

Neuralink, Elon Musk’s startup that’s trying to directly link brains and computers, has developed a system to feed thousands of electrical probes into a brain and hopes to start testing the technology on humans in in 2020, Chief Executive Elon Musk revealed Tuesday. And it’s working already in animal tests. “A monkey has been able to control a computer with his brain,” Musk said at a San Francisco Click on photo to start video.

Neuralink’s initial goal is to help people deal with brain and spinal cord injuries or congenital defects, Musk said. The technology could help paraplegics who have lost the ability to move or sense because of spinal cord injury — a medical treatment that’s a lot less shocking than radical sci-fi ideas like “consensual telepathy.”

Neurons and cancer cells are a dangerous duo

New clues on why women’s Alzheimer’s risk differs from men’s

Posted by in categories: biotech/medical, neuroscience, sex

LOS ANGELES (AP) — New research gives some biological clues to why women may be more likely than men to develop Alzheimer’s disease and how this most common form of dementia varies by sex.

At the Alzheimer’s Association International Conference in Los Angeles on Tuesday, scientists offered evidence that the disease may spread differently in the brains of women than in men. Other researchers showed that several newly identified genes seem related to the disease risk by sex.

Two-thirds of Alzheimer’s cases in the U.S. are in women and “it’s not just because we live longer,” said Maria Carrillo, the association’s chief science officer. There’s also “a biological underpinning” for sex differences in the disease, she said.

All species of Datura are poisonous, especially their seeds and flowers which can cause respiratory depression, arrhythmias, hallucinations, psychosis, as well as death if taken internally.


All Datura plants contain tropane alkaloids such as scopolamine, hyoscyamine, and atropine, primarily in their seeds and flowers as well as the roots of certain species such as D. wrightii.
