Brain to Brain interface in real time. It has happened. Now what?

Depression induced or cured within 10 seconds in rats by turning on or off neurons that release dopamine in the ventral tegmental area of the brain with the help of optogenetics (previously changing neurons to make them be turned on or off by focusing light on them). 10 seconds is shorter than the time that antidepressants usually take to work, which is some weeks. Treatment with magnesium may work within one week, and could be combined for best results with vitamin D, vitamin B12, folic acid, and omega-3.

Sleep Snob Technology is self-hacking at its best. 

“Sleep tracking is in vogue. You can buy gadgets shaped like headsets, bracelets, and thumb drives even under-mattress sensor pads that will track a whole constellation of sleep indicators—body temperature, movement, electrical activity in your brain—as you slumber.

The Lullaby, a prototype tracker built at the University of Washington goes one step further. It doesn’t just show when you weren’t resting well, it helps you understand why your Zs were thrown off. It tracks your sleeping environment, picking up things like room temperature, ambient light intensity, background noise—and matches those up with biological sleep signs mapped by the wrist-worn Fitbit. An IR camera takes a photograph of the sleeping subjects every 15 seconds, adding a staggered video log to sleep data being collected. Over a morning cup of coffee, on a tablet app, a user can flick through data gathered the previous night.”

A Harvard professor has hatched a plan to bring back the Neanderthals—but he needs an “adventurous” female volunteer to deliver a knuckle-dragging bundle of joy.

A longer interview with George Church, the man proposing the experiment, can be read here.

“Now, it should be noted that the researchers aren’t trying to emulate a complete honey bee brain, but rather two specific and complex functions within it, namely vision and sense of smell.”

“By isolating and modeling these particular functions, the researchers hope to provide their flying robot with the cognitive power required to perform basic tasks — and without a set of pre-programmed instructions. It is hoped, for example, that the robotic bee will be able to detect particular odors or gasses in the same way that real bee can identify certain flowers.”

Social exclusion is linked to the pain regulation center of our brain.

In this study, students who received stimulation to the portion of the prefrontal cortex responsible for pain regulation didn’t seem bothered when they were deliberately excluded in a ball tossing game.
