Scientists found a site for intention located in the parietal cortex, using brain stimulation techniques. They contrast the "desire to move" caused by stimulation of this area with the "unconscious movement" caused by stimulation of frontal premotor areas. (via Warren Ellis)
In other news, other scientists found a gamma secretase related drug that breaks up amyloid clots in Alzheimer's patients. Other preclinical methods include a histone deacetylase manipulator that helps reconfigure DNA to enhance the recovery and disposal mechanisms in Alzheimer's brains.
