Spatial resolution, temporal resolution, and invasiveness of available techniques for the study of brain function (adapted from Churchland PS, Sejnowski TJ. Science 1988;242:741). Spatial resolving power is shown on the vertical axis and temporal resolution is plotted on the horizontal axis. Invasiveness, defined loosely as the risk of significant disruption of normal function or health of the subject, is plotted by gray shading. Dynamic magnetic resonance imaging (MRI) gathers functional information related to cerebral hemodynamics and is appropriate for the study of a variety of cognitive functions. MEG : magnetoencephalography; ERP : evoked response potential (electroencephalography); PET: positron emission tomography; 2-deoxyglucose : autoradiography.
