Unraveling the mysteries of the human brain, and the mind it gives rise to, is within the reach of modern science, suggests a forthcoming issue of the journal Neuroscience. The special issue explores how sophisticated working memory processes — from the firing of a single neuron to the activation of multiple brain regions — help shape our understanding of the world, says issue co-editor Grega Repovs, a visiting post-doctoral fellow at Washington University in St. Louis.

Deanna Barch (center) discusses brain imaging techniques used in the experiment, which used the functional magnetic resonance imaging (fMRI) machine (shown at right).When encouraged to use memorization strategies commonly employed by healthy individuals, people with schizophrenia can be helped to remember information just as well as their healthy counterparts, a process that in itself seems to spur a normalization of memory-related activities in the brains of people with schizophrenia, suggests new research from Washington University in St. Louis.

Joshua Brown of WUSTLA new theory suggests that the brain may subconsciously help us avoid risky situations.While some scientists discount the existence of a sixth sense for danger, new research from Washington University in St. Louis has identified a brain region that clearly acts as an early warning system — one that monitors environmental cues, weighs possible consequences and helps us adjust our behavior to avoid dangerous situations. “Our brains are better at picking up subtle warning signs than we previously thought,” says WUSTL research psychologist Joshua Brown, co-author of a study on these findings in the Feb. 18 issue of the journal Science.

That is the implication of a detailed study of the neuronal activity in a critical area of the brain, called the anterior cingulate cortex (ACC), published in the Oct. 3 issue of the journal Science. The finding is important because the ACC plays a key role in disorders such as schizophrenia and obsessive-compulsive disorder in humans, suggests Joshua Brown, study co-author and WUSTL research associate in psychology.
