With a chilling hint of the not-so-distant future, researchers at the Usenix Security conference have demonstrated a zero-day vulnerability in your brain . Using a commercial off-the-shelf brain-computer interface, the researchers have shown that it’s possible to hack your brain, forcing you to reveal information that you’d rather keep secret. As we’ve covered in the past, a brain-computer interface is a two-part device: There’s the hardware — which is usually a headset (an EEG; an electroencephalograph) with sensors that rest on your scalp — and software, which processes your brain activity and tries to work out what you’re trying to do (turn left, double click, open box, etc.) BCIs are generally used in a medical setting with very expensive equipment, but in the last few years cheaper, commercial offerings have emerged. For $200-300, you can buy an Emotiv (pictured above) or Neurosky BCI, go through a short training process, and begin mind controlling your computer.
Consciousness is more familiar to us than any other feature of our world, since it is the route by which anything at all becomes familiar.

(Santa Barbara, Calif.) –– Scientists at UC Santa Barbara have made a major discovery in how the brain encodes memories. The finding, published in the December 24 issue of the journal could eventually lead to the development of new drugs to aid memory. The team of scientists is the first to uncover a central process in encoding memories that occurs at the level of the synapse, where neurons connect with each other.

At one time in history, decapitation was one of the preferred methods of execution, in part thanks to the guillotine . Although many countries that execute criminals have dispatched with the method, it's still performed by certain governments, terrorists and others. There's nothing more final than the severing of one's head. The guillotine came about because of the desire for a quick, relatively humane death. But how quick is it?
Jellied Century-Old Brains Reveal Secrets of Mental Illness | Insane Institution & Dementia | Brain Disorders & Brain Autopsy | LiveScienceBOUNCY BRAIN: Old brains preserved in gelatinous celloidin promise new insights into mental illness. But first scientists must figure out how to extract their DNA.

Nov. 15, 2011 — How the brain perceives color is one of its more impressive tricks. It is able to keep a stable perception of an object's color as lighting conditions change. Sarah Allred, an assistant professor of psychology at Rutgers-Camden, has teamed up with psychologists from the University of Pennsylvania on groundbreaking research that provides new insight into how this works.
