Abstract: Disclosed herein is a technique for observing the insular cortex activity by using electroencephalograms. A method for sampling cerebral insular cortex activity includes: recording electroencephalograms (EEGs) provided by a plurality of EEG electrodes; creating a three-dimensional model in the form of a mesh in which a subject's brain is decomposed into a plurality of sites according to the subject's brain structure and positioning the plurality of EEG electrodes by reference to an image representing the subject's brain and head structure; creating a forward model by modeling a correlation between the activities of the respective brain sites of the three-dimensional model and an electroencephalogram distribution of the positioned EEG electrodes; and associating, by reference to information about a region of interest measured by functional magnetic resonance imaging (fMRI) and the forward model, data about the electroencephalograms recorded with the cerebral activity of the region of interest.

Abstract: Described is a counting apparatus for counting paper sheets settable when effecting a batch counting to a clear mode in which the count data obtained in the counting operation of each preceding batch of paper sheets are cleared for counting a new batch or to an add mode in which the count data for the current batch is added to the count data for the preceding batch or batches and the resulting sum of the count obtained until the current time is displayed.
