Toronto: Ladies, having trouble concentrating? Blame it on your hormones, Canadian scientists say.Researchers at the Concordia University in Montreal found that high estrogen levels are associated with an inability to pay attention and learn.The study, the first to report how hormones can have a direct impact on this impediment, has been published in the journal Brain and Cognition.
Once they became used to this tone and ignored it, the test dynamics changed and another stimulus was linked to the tone.Rats with low levels of estrogen quickly learned that the tone was associated with the new stimulus whereas those with higher levels of estrogen took longer to form this memory.Brake said: "We only observed this effect in adult female rats. This and our other findings indicate that estrogen directly effects the brain, perhaps by interfering with brainsignalling molecules”."Our study helps clear up the controversy about the effects of estrogen, the next step is to look at how this occurs."PTI
