Scientists identify 2 distinct Parkinson's networks

Parkinson's that causes tremors, rigidity and slowed movements also targets another brain network that regulates cognitive thought and the ability to carry out everyday tasks. David Eidelberg, MD, head of the Center for Neurosciences at the Feinstein Institute for Medical Research, and his colleagues measured and quantified this network of brain regions during a five-year study of newly diagnosed Parkinson's patients who agreed to be followed several times over the course of the study.

3. Brain network related to intelligence identified
   09-11-2007 · EurekAlert!
   Researchers have uncovered evidence of a distinct neurobiology of human intelligence. This Parieto-Frontal Integration Theory identifies a network related to intelligence, one primarily involving areas in the frontal and the parietal lobes. The data suggest that some of the brain areas related to intelligence are the same areas related to attention, memory and language. This possible integration of cognitive functions suggests that intelligence levels might be based on how efficient the frontal-parietal networks process information.
