Experts find new window to brain
Scientists claim to have discovered an intriguing new window into the human brain, via the visual system, a finding wh-ich may have implications for managing disorders like insomnia and epilepsy.
An international team, led by Dr Sam Solomon and Prof Paul Martin of the Vision Centre and the University of Sydney, has published its findings in the Proceedings of the National Academy of Sciences journal.
“It was purely a chance observation we made while we were activating the three cell layers of the lateral geniculate nucleus (LGN) which is the part where the optic nerve actually connects to the brain,” Prof Martin said.
Two of these layers are linked with human ability to perceive edges and movement; the third, koniocellular or “K” layer, is much more primitive — part of our deep evolutionary ancestry — and its function is still mysterious, he said. “When we stopped applying a stimulus, two of the three layers ceased to respond while the K layer continued to pulse, slowly and rhythmically — like a sleeping brain,” he added.

Sheen is pelted with beer cans
London: Charlie Sheen had to run off the stage after being booed and pelted by beer cans at a hip-hop festival. The former Two And A half Men star came onstage to announce rapper Tech N9ne during the Gathering of the Juggalos hip-hop festival but the crowd started to boo and jeer Sheen.
It soon got worse for the actor as he started getting pelted by a variety of missiles from the Illinois audience. Sheen remained in control and even joked that it reminded him of his disastrous Motor City performance, the Daily Mail reported. —PTI
