Women in the ovulation of difficulty in concentrating

Women tend to feel tired at some stage or difficulty in concentrating. According to foreign media reports on September 26, the latest "Brain and Cognition" magazine published a new study in Canada found that women concentrate hard and closely related to menstrual cycle hormonal changes.

 
Comcast Concordia University, Canada, scientists completed the first of the new study shows that high estrogen levels and lack of concentration and impaired learning ability are directly related. Study found that female estrogens will have a direct impact on adult brain structure.
Comcast Concordia University professor of behavioral neurobiology research center, said Wayne Black, although the study also found that estrogen in the process of learning and memory play an important role, but on the effect of estrogen on the specific role of the brain, but has not been clear the same conclusion.

 
Professor Black and his colleagues using the "latent inhibition" model (a learning model) completed the study mice. At the start, a group of adult female mice to listen to a sound, while giving their favorite food to eat. These mice have a "food - voice" association. After the change, after the sound stimulation, low levels of estrogen in adult female rats quickly regain "food - the new voice of" association. The higher levels of estrogen in adult female rats was significantly slower learning a beat. The study concluded: high levels of estrogen on cognitive abilities of female rodents inhibited. Study found the same token, a relatively high ovulation estrogen levels can interfere with the ability of women to focus.

 
The first of the new study, Dr. Matthew Quinlan, Comcast, Dr. Concordia University after reading into the California State University San teach. Dr Quinlan said the results of rodent experiments is important, help to eliminate the effects of estrogen on the brain of various disputes, but also help identify the real reason for the attention of women. But he also pointed out that the human body to be launched next compare the relative difficulty of a larger experiment.
