To translate touch, the brain can quickly rearrange its sense of the body

...e experiments felt within seconds that their right elbow was rotating away from the body, even though the arm was actually quite still. If subjects held their left index finger with their right hand while this happened, they felt their left index finger getting longer as they felt their arm move. The team...

Neurons find their place in the developing nervous system with the help of a sticky molecule

...us of the current study, are born last and so must elbow their way through cells lying in earlier formed layers to reach what will become the outermost layers. Without MDGA1, these neurons begin to migrate but get stuck before they reach their normal destination. The MDGA1 gene was cloned and characterize...

University of Utah to help build bionic arm

...models have limited movements, such as bending the elbow and wrist and opening and closing the hand, while the new arm will be capable of about 20 different movements, including moving fingers independently, says Clark. Existing prosthetic arms typically are controlled by signals from an intact muscle, s...

Both alcoholism and chronic smoking can damage the brain's prefrontal cortex

...models have limited movements, such as bending the elbow and wrist and opening and closing the hand, while the new arm will be capable of about 20 different movements, including moving fingers independently, says Clark. Existing prosthetic arms typically are controlled by signals from an intact muscle, s...

How ancient whales lost their legs, got sleek and conquered the oceans

...ed for normal limbs to develop beyond the knee and elbow joints. Because ancient whales' hind limbs remained perfectly formed all the way to the toes even as they became smaller suggests that Sonic hedgehog was still functioning to pattern the limb skeleton. The new research shows that, near the end of 15...

Life and death in the hippocampus: what young neurons need to survive

...a dangerous place for a fledgling neuron trying to elbow its way into pre-existing networks. "It's rough in there!" he concedes. "The NMDA receptor-mediated event is a competition between mature cells vying for connectivity and young guys competing with both the mature cells and their peers to fit in. You ...

New biologic treatment for tennis elbow may replace surgery for chronic sufferers

A person suffering from tennis elbow may not have to look any further than his or her o...e then re-injected into the tendon of the affected elbow provides more relief than more commonly-used therapies which have failed to yield results, often res...
