Method: AnalysisMethod: Analysis

Cortical analysis using NeuroGuideBy conditionCondition subtraction

Analysis of DC source potential using EureKa3!, LORETA Key, and Mhyt3

By conditionCondition subtraction: Significant differences ( p < .05)


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)
