Differential brain activation contrasting erotic minus non-erotic stimulation.

<p>Depicted are contrasts from experimental runs with video (A), picture (B) and picture expectation (C) stimuli during luteal and follicular phase of the menstrual cycle and under oral contraceptives. The rightmost panel depicts the conjunction of the three conditions. For demonstration purposes, all thresholds were set at p<0.005 uncorrected. Even at such a more lenient threshold, no differential brain activation was found under contraceptives upon picture expectation.
