This was all caused by fluctuations in estrogen during the menstrual cycle until later when entering the time of ovulation or (fertile period).
Just so you know, estrogen could trigger the release of dopamine. Dopamine is a hormone that triggers the pleasure of working memory can also increase the brain for short-term and help concentration.
Now, each healthy women had higher levels of dopamine are different, some high and some low.If you have high dopamine levels, intelligence is usually quite high, whereas if low dopamine levels have to fight in a complex working memory tasks.
When a team from the University of California, Berkeley, studied the hormone estrogen and dopamine fluctuations during the menstrual cycle until ovulation the uniqueness found in women. Apparently high levels of dopamine which makes women so slightly decreases the brain's ability during menstruation.
During the fertile period of women who have high estrogen levels (usually 10-12 days after menstruation) found that women naturally have high dopamine levels do not have a good ability.
"For women with low dopamine levels, approximately 25 percent will increase during ovulation so that they can sharpen cognitive function. While 25 percent of women who have high dopamine levels, will make it exceed the limit and hurt the ability to think when she was ovulating," says Emily Jacobs, PhD conduct this study, as quoted from Scientific America, Monday (19/4/2010).
Jacobs added that this was affecting the ability of a woman in thought. At certain times a woman can have a good cognitive function but can also function to decrease.
Use of the drug caffeine which can trigger the release of dopamine or the drug Ritalin to be less effective or it can be harmful for some women if consumed at certain moments, when estrogen affects the body. (detikhealth)
