Researchers say you are more likely to scan the room, jumping from face to face as you search for your friend. In addition, the timing of these jumps appears to be determined by waves of activity in the brain that act as a clock.
Early visual areas of the brain may have a role in memory The traditional view is that perceptual information is processed in early sensory regions of the brain, such as primary visual cortex, before being passed on to memory systems subserved by "high-order" brain areas, such as the prefrontal and inferotemporal cortices. Aside from being an oversimplification, a further problem with this account is that the the high-order brain regions don't have the
The Human Brain Is On The Edge Of Chaos Researchers have provide new evidence that the human brain lives "on the edge of chaos," at a critical transition point between randomness and order. The study provides experimental data on an idea previously fraught with theoretical speculation.
The Brain Maintains Language Skills In Spite Of Alcohol Damage By Drawing From Other Regions Researchers know that alcoholism can damage the brain's frontal lobes and cerebellum, regions involved in language processing. Nonetheless, alcoholics' language skills appear to be relatively spared from alcohol's damaging effects. New findings suggest the brain maintains language skills by drawing upon other systems that would normally be used to perform other tasks simultaneously.
The Brain 'Joins The Dots' When Drawing A Cartoon Face From Memory Scientists used a brain scanner to record the brain's activity in each stage of the process of drawing faces. The researchers found that the captured visual information is stored as a series of locations or action plans to reach those locations. It is as if the brain remembers key locations and then "joins the dots" with a straight or curved line to achieve the desired image on the page.
