Abstract

The effect of increasing the number of scans in the cluster of an interleaved silent steady state (ISSS) fMRI imaging scheme from 1 to 2, and then to 3 was examined by a fixed-effects analysis of an auditory short-term memory task with four subjects. Compared to a cluster size of 1, a cluster of 2 scans improved sensitivity at detecting brain activity and statistical power, while a cluster of 3 scans further improved statistical power but seemed not to improve sensitivity beyond that achieved with a cluster of 2 scans. The findings reveal that cluster size is a vital parameter for an ISSS imaging scheme.
