Abstract:Regional cerebral blood flow measurements were made in the left hemisphere of 11 young healthy volunteers during learning and during recalling of word pair associates. Compared to the resting baseline, both tasks caused significant increases of average hemispheric flow, indicating an elevated neuronal activity level. Regionally both tasks were accompanied by considerable activation of parietal and occipital regions. The main difference between learning and recalling was that only the former task activated the prefrontal regions.
