A functional area of a human brain is usually activated by multiple stimuli, and category-selective areas (i.e. fusiform face area & parahippocampal place area) are also activated by a non-preferred stimulus as well as the preferred stimulus. With using conventional fMRI method, it is difficult to know whether all of the neurons in activated areas respond to both the preferred and non-preferred stimuli or whether a part of neuronal population is separately activated by each stimulus. In the present study, we measured fMRI responses using multi-echo-train echo-planar-imaging to discriminate the neuronal populations in a functional area.
