How To Hack A Human Brain | VICE on HBO

Posted by in categories: biotech/medical, cybercrime/malcode, neuroscience

Advancements in neurotechnology are blurring the line between biology and technology. There is an emerging push to implant electronic devices inside the human body, hardwire them to our brains, and allow us to not only overcome disadvantages or injury but open up entirely new avenues of human experience.

VICE’s Thomas Morton got an inside look at what might be the next evolutionary step for humankind.

Functional brain architecture is associated with the rate of tau accumulation in Alzheimer’s disease

Posted by in categories: biotech/medical, neuroscience

Tau accumulation is associated with disease progression in Alzheimer’s disease. Here the authors use resting state fMRI and tau-PET to demonstrate that baseline connectivity in Alzheimer’s disease is associated with tau spreading.

7 rules to reduce your risk of Alzheimer’s and keep your brain healthy

Posted by in categories: biotech/medical, neuroscience

This article is reprinted by permission from NextAvenue.org.

During the last Alzheimer’s disease support meeting I attended at my mother’s assisted living center, I sheepishly asked if anyone else was worried about their own risk for the disease.

A lot of hands went up.

Belgian brain doctor awarded for easing coma survivors’ return

Posted by in categories: biotech/medical, neuroscience

Not all patients who fall into a coma return, and when they do it can mark a moment of joy for their loved ones—but their troubles are rarely over.

Often, brain damage leaves them paralysed or unable to communicate.

Belgian neurologist Steven Laureys has dedicated himself to the question of how to improve the lives of the formerly comatose, and of their families.

Microscopy technique reveals cells’ 3D ultrastructure in new detail

Posted by in categories: biotech/medical, neuroscience

Inside a cell, tentacled vesicles shuttle cargo for sorting. DNA rearranges in the nucleus as stem cells differentiate into neurons. Neighboring neurons cling to one another through a web-like interface. And a new microscopy technique shows it all, in exquisite detail.

The technique, called cryo-SR/EM, melds images captured from and super-resolution light microscopes, resulting in brilliant, clear detailed views of the inside of —in 3D.

For years, scientists have probed the microscopic world inside cells, developing new tools to view these basic units of life. But each tool comes with a tradeoff. Light microscopy makes it simple to identify specific cellular structures by tagging them with easy-to-see fluorescent molecules. With the development of super-resolution (SR) , these structures can be viewed with even greater clarity. But fluorescence can reveal only a few of the more than 10,000 proteins in a cell at a given time, making it difficult to understand how these few relate to everything else. Electron microscopy (EM), on the other hand, reveals all cellular structures in high-resolution pictures—but delineating one feature from all others by EM alone can be difficult because the space inside of cells is so crowded.
