    • Statistical, Parametric Mapping (Wellcome Department of Cognitive Neurology, London, 1999). Statistical parametric maps, SPM(t)s, were calculated for condition-specific effects within a general linear model. All modeled events and epochs were convolved by a canonical hemodynamic response function. Low-frequency changes in BOLD signal over time were modeled with discrete cosine functions of periodicity ranging from 400 to 2400 s. The data were temporally smoothed by a canonical hemodynamic response function and by intrinsic temporal autocorrelations modeled by a first-order autoregression algorithm [G.K. Aguirre, E. Zarahn, M. D'Esposito, Neuroimage 5,199 (1998)]. Voxels were identified at which the probability of the observed condition-specific activation was less than 0.05, corrected for multiple comparisons (corresponding to t statistic >4.91). Contrasts discussed include the main effects each of visual stimulus presentation, motor response, and selection against baseline, and the contrast of working memory delay versus an equivalent period in control trials (memory versus nonmemory epochs).

    • note
    • For any voxel, the sum of all modeled covariates multiplied by their empirically derived parameter estimates provides the best fit to the data for each participant. These fitted data were temporally realigned to the start of working memory trials and averaged across participants for each length of working memory trial. These data were scaled to represent best-fitted percentage change in the BOLD signal (z axis) over time (x axis), separately for each length of memory (y axis) (Fig. 3, C through D, and Fig. 4, C through D).
