High levels of estrogen directly affect the brain

Canadian scientists at Concordia University in Montreal have discovered that high levels of estrogen in women during their ovulation may have a direct impact on their distracted or slow expressions.

This study was published in the Journal of Brain and Cognition in September.

In a statement, scientists say that this is the first study to show that this obstacle may be due to the direct effect of hormones on mature brain structures.

" Although estrogen is still known to play an important role in learning and memory, there is no clear consensus about its effects, " said research director Wayne Brake.

Scientists conducted an experiment with mice, they exposed the mice several times with a melody. After these mice became accustomed to the melody and did not pay attention to it, scientists added some stimuli to the melody. The results showed that mice with low estrogen levels quickly found new points in the melody, while mice with higher estrogen levels took longer.

Estrogen stimulates the development and differentiation of epithelial cells of epithelial cells, cell division of cylindrical epithelial cells and organization of association, enhances local circulation at the mammary gland with similar effects. self of histamine.

The amount of estrogen receptor at the mammary gland is highest in the early stages of follicular development and lowest after ovulation.

According to the hypothesis of the conversion of testosterone to estrogen in the central nervous system, estrogen is able to stimulate secretion of gonadotropin (FSH, LH, Prolactin) through which to determine the sex characteristics of brain activity. the set. The speed and rate of turning testosterone into estrogen is lower in the brain than in other organs.

However, locally synthesized estrogen is thought to play a very important role. Estrogen has the ability to protect nerve cells, restore sinap .

In graph regions, estrogen increases the density of N-methyl-D-aspartate receptor and increases the susceptibility of nerve cells through those receptors. Estrogen also has the ability to protect nerve cells in artificial culture, reducing beta-amyloid peptide levels.
