Significant condition-by-hormonal levels interaction effects (whole brain analysis).

nC-group: women not taking hormonal contraceptives; F: mid-follicular phase of menstrual cycle; L: mid-luteal phase of menstrual cycle; C-group: women taking hormonal contraceptives; r: right; l: left; no significant interactions for nC-F>nC-L; #: activation maximum is part of cluster above. Group comparisons surviving an FDR corrected threshold of p<0.05 are marked by MNI-coordinates in bold type (a tilde behind the z-coordinate denotes significance at p<0.05, FWE corrected); an asterisk (*) denotes group differences at an uncorrected level of p<0.001 with cluster sizes of at least 10 contiguously significant voxels; t: t-value; NV: number of contiguously significant voxels; peak coordinates of clusters are MNI (Montreal Neurological Institute) normalized stereotactic coordinates: -x: left from the anterior commissure (AC); -y: posterior from AC; -z: inferior from AC. DLPFC: dorsolateral prefrontal cortex; DMPFC: dorsal medial prefrontal cortex; BA: Brodman area.
