No, we're not talking shock therapy. Researchers at the University of Toronto installed deep brain stimulating electrodes in 20 patients with severe depression who weren't helped by other means. Twelve of those individuals saw big improvement and seven experiences a "full remission." The electrodes stimulated a region of the brain called the subcallosal cingulated gyrus. Other centers around the world are running similar studies but zapping different parts of the brain.
“In the meantime we need to know why some of the patients don’t respond at all,” says (researcher Helen) Mayberg. “Are we missing the target, or are there different subtypes of the disease?” Her team is now trying to find out how to identify those who will respond to DBS, and those who won’t. “Brain surgery is not like getting your nails done, so it is important to try to find out who will benefit..."

Neurologists think that the therapy works by activating or damping down particular brain circuits. At the moment, no-one knows which of the targets within these circuits will eventually prove to be the most optimal...

Even though credit cards now feature an EMV chip for securing transactions, they still have to include the magnetic strip for compatibility with older point of sale systems. Because of this, there’s no way for the chip’s new security capabilities to protect against card skimmers in the wild.How do you protect yourself from legacy-technology-induced fraud? […]
As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
