Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 413)


The classical model of neuronal metabolism holds that changes in local neuronal activity are reflected in changes of blood flow (rCBF) and oxygen metabolism (rCMRO2). This model has been examined in human PET [1,2] and animal [3] studies.
