Moving into a robotic hand

Here is another wonderful Mindhacks post: Inhabiting a robot hand Thank you Mindhacks.

This relates to all the posts here to do with robotics, haptics, virtual bodies, virtual body manipulation through mirror therapy or video, and rubber hand illusions. NOI twittered about the Mindhacks post in conjunction with Graded Motor Imagery, the virtual treatment they are promoting. Definitely worth boosting here as well.

Forty Years of Neuroscience

I want to thank MindHacks for constructing such an informative post. Here it is, complete with all its links to Journal of Neuroscience.
Around the Brain in Forty Years.

Self-amputation

There must be dozens of stories of this. A few years ago Oprah had as a guest a young woman who, trapped in a car which had gone off a bridge, hidden from view and possible rescue, self-amputated a leg to escape. About 5 years ago a young man hiking in the Grand Canyon became trapped when a rock tumbled and pinned his hand. He cut off the hand to escape.

It really makes one wonder what pain is, exactly.

In this story from yesterday (twittered by Mo of Neurophilosophy), a young man's leg was pinned by a concrete girder. He managed to cut most of it off himself, but a friend nearby had to help break the bone.

His brain decided the threat to his ongoing existence was greater than any threat from any upcoming nociception. It was capable of downregulating its own sensory input enough to allow him to remain conscious and focused and on task, as it realized this was its organism's only shot at surviving. In this way the seemingly impossible becomes possible, without loss of consciousness, and in spite of what must be a large loss of blood.
