Mimicking the brain, in silicon - MIT News Office

Mimicking the brain, in silicon - MIT News Office
For decades, scientists have dreamed of building computer systems that could replicate the human brain’s talent for learning new tasks.
MIT researchers have now taken a major step toward that goal by designing a computer chip that mimics how the brain’s neurons adapt in response to new information. This phenomenon, known as plasticity, is believed to underlie many brain functions, including learning and memory.

Is Neuroscience the Death of Free Will? - NYTimes.com

Is Neuroscience the Death of Free Will? - NYTimes.com:
Philosopher Eddy Nahmias in the New York Times:
Is free will an illusion? Some leading scientists think so. For instance, in 2002 the psychologist Daniel Wegner wrote, “It seems we are agents. It seems we cause what we do… It is sobering and ultimately accurate to call all this an illusion.” More recently, the neuroscientist Patrick Haggard declared, “We certainly don’t have free will. Not in the sense we think.” And in June, the neuroscientist Sam Harris claimed, “You seem to be an agent acting of your own free will. The problem, however, is that this point of view cannot be reconciled with what we know about the human brain.”
