Some fibers from the ventral cochlear nucleus cross the midline in the trapezoid body. Thus, cells in the superior olive receive inputs from both ears and are the first place in the central auditory system where binaural processing (stereo hearing) is possible. The output of the superior olive travels in the lateral lemniscus.
Delay caused by a short stress time is usually a week or two, then you ovulate normally. However, under continued stress (heavy exercise, malnutrition, etc.) you can be anovulatory for a very long time. If you are having problems in this area, have a look at this book: Fertility, Cycles & Nutrition 4th Edition.
Illness Like stress, illness can also make your period late. If you are ill around the time you would have ovulated, this may keep you from ovulating or temporarily delay ovulation. If ovulation is late, your period will be late as well. If your period is late, think back to how you were feeling a couple weeks earlier. If you were sick, this could very well explain why your period hasnât showed up. Eating Disorders Having an eating disorder or being underweight can disrupt your menstrual cycles or cause them to stop all together.
