Abstract
Pharmacological studies are currently performed in men and
not in women due to the absence of methodological or conceptual
information concerning the effects of the menstrual cycle. This is the first
study in which three different sensory stimuli were applied to females in
an omitted stimulus reaction time (OSRT) task during three phases of the
menstrual cycle. Eleven college volunteers with regular menstrual cycles
responded to lateralized trains of visual, auditory, and somatosensory stimuli.
A participant’s OSRT was recorded for each trial performed during the
menstrual (day 2-3), follicular (day 7-8), and luteal (day 21-22) phases. The
results showed that the ovarian cycle has no effects on the OSRT task in
any of the sensory modalities, but the reaction to the missing auditory
stimuli was found to be systematically faster than the reactions to the
visual and somatosensory stimuli (P<0.002). Thus the OSRT is affected by
sensory modality but not by the normal menstrual cycle.
