New research at the University of Illinois at Urbana-Champaign shows that training re-ignites key areas of the brain, offsetting some age-related declines and boosting performance. The findings, involving functional magnetic resonance imaging (fMRI), provide the first visible evidence for a relationship between behavioral performance and cortical processors involved in dual-task processing, said Arthur F. Kramer, a professor of psychology and researcher at the Beckman Institute for Advanced Science and Technology.

The study, published online this month in advance of regular publication by the journal Neurobiology of Aginng, also adds to other emerging data that refute the idea that opposite brain areas become activated to help aging people compensate for a loss of cognition. Older studies, Kramer said, did not look at the impacts of training. For the new study, researchers in Kramer's lab looked at areas of the brain known to be associated with executive control - scheduling, planning, juggling multiple tasks and working memory. These areas, the ventral and dorsal prefrontal cortexes, are tied to cognitive declines in aging.

Using electroencephalography (EEG), psychophysiology, and psychometric measures, this is the first study which investigated the neurophysiological underpinnings of spatial presence. Spatial presence is considered a sense of being physically situated within a spatial environment portrayed by a medium (e.g., television, virtual reality). Twelve healthy children and 11 healthy adolescents were watching different virtual roller coaster scenarios. During a control session, the roller coaster cab drove through a horizontal roundabout track. The following realistic roller coaster rides consisted of spectacular ups, downs, and loops. Low-resolution brain electromagnetic tomography (LORETA) and event-related desynchronization (ERD) were used to analyze the EEG data. As expected, we found that, compared to the control condition, experiencing a virtual roller coaster ride evoked in both groups strong SP experiences, increased electrodermal reactions, and activations in parietal brain areas known to be involved in spatial navigation. In addition, brain areas that receive homeostatic afferents from somatic and visceral sensations of the body were strongly activated. Most interesting, children (as compared to adolescents) reported higher spatial presence experiences and demonstrated a different frontal activation pattern. While adolescents showed increased activation in prefrontal areas known to be involved in the control of executive functions, children demonstrated a decreased activity in these brain regions. Interestingly, recent neuroanatomical and neurophysiological studies have shown that the frontal brain continues to develop to adult status well into adolescence. Thus, the result of our study implies that the increased spatial presence experience in children may result from the not fully developed control functions of the frontal cortex.
