LORETA Difference AnalysisLORETA Difference Analysis
Absolute (LORETA) average power, normalized
Current density power log transformed to approximate gaussianity of the frequency distribution
Subtraction analysis: Condition1 Condition2
Distribution differences tested by voxel by voxel nonparametric t-statistic corrected for multiple comparisons, controlled with family-wise error at 0.01
Unpaired t-tests (for equal variances), two-tailed
LORETA analysis of three-dimensional distribution of the frequency band generators: current density values of 2,394 voxels, spatial resolution 7 mm in cortical areas defined by Talairach atlas

Delta Waves in Waking ConsciousnessDelta Waves in Waking Consciousness
Reported during mental calculations & abstract thought (Fernandez, et al., 1995; Michel, et al., 1993)
Cortico-fugal pathway disconnection of cortex from environmental stimuli (Fernandez, et al., 1995)
Interpolation of activity across association cortex (Alper, 1999)
Active at CZ in Australian healer (Wilson, 1993)
Given Shealys et al. (2000) study of distant healing, may represent non-local mind (DeLuca & Daly, 2003)
