...neurocognitive ageing is to understand age-related changes in brain-behaviour relationships. Neuroimaging techniques such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) can be used for observation of these age-related changes only if the assumption of age-equivalent relations... | |

...their hypotheses in sufficient detail to provide the basis for future modelling work. Brain imaging Techniques such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) reveal the brain areas that are most metabolically active during different cognitive tasks. Research... | |

While some of the answers will undoubtedly come from functional brain imaging untilizing techniques such as positron emission tomography (PET)...and functional magnetic resonance imaging (fMRI), we do not yet understand fully the functional role and interrelationship of brain regions subserving... | |

...dramatically during the 1990s due to the advent of hemodynamic neuroimaging (Posner & Raichle, 1994). Methods such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) allow the volumetric variations in regional cerebral blood flow that are correlated with cognitive... | |

These hemodynamic (and metabolic) changes can be monitored with techniques such as positron emission tomography (PET)...and functional magnetic resonance imaging (fMRI). Local changes in blood flow during a cognitive task, for example, can be followed with PET using 15... | |

Recent work using imaging techniques such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) has revealed conflicting data. While some have shown bilateral hemisphere activation during image generation... | |
