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.
Worrying can cause your period to be a day or two late, but it wonât push your period out much later than that. If you ovulated around the time you normally do, your period should arrive within 14 to16 days after ovulation, whether you are under stress or not.
