Effect of Estrogen on The Learning Process.



Concordia University has new research published in the popular journal, Brain and Cognition, showed high levels of estrogen, such as those found during the female ovulation, have influence on attention and learning.

    "Although estrogen is known to play a significant role in learning and memory, there has been no clear consensus on its effects," says senior author Wayne Brake, an associate professor at Concordia's Centre for Studies in Behavioural Neurobiology. "Although estrogen is known to play an important role in learning and memory, there is no clear consensus about its effects," says senior author Wayne Brake, a professor at Concordia Centre for Studies in Behavioral Neurobiology. "Our Findings, using a well-established model of learning Called latent inhibition, shows conclusively That high estrogen levels inhibit the cognitive abilities in female rodents." "Our findings, using an established model of learning called latent barriers, showed conclusively that high estrogen levels inhibit the cognitive abilities in rodents women."

Findings in this study resulted from experiments on the latent inhibition of Rats. The findings in this study originated from the latent inhibition experiments on rats. Latent inhibition is a term derived from classical conditioning. latent inhibition is a term derived from classical conditioning. It occurs Pls a subject takes longer to give meaning to a stimulus That Had no previous Than It would Pls significance associated with a new stimulus. This occurs when the subject is taking longer to give meaning to the stimulus that has no previous meaning of it will be when it comes to new stimuli. It is a natural tendency to disregard or inhibit forming a memory by preventing associative learning of a stimulus associated with no consequence. This is a natural tendency to ignore or inhibit the shape memory by preventing associative learning-related stimulus without consequence. It is an unconscious response and Presumed to Prevent sensory overload. It was a subconscious response and is considered to prevent sensory overload. "Latent inhibition is observed in many species, and is believed to be an integral part of learning, enabling an organism to Interact successfully in an environment." "Latent inhibition was observed in many species, and is believed to be an integral part of learning, which allows the organism to interact successfully in the environment. "

The research team discovered That estrogen has a direct effect on the brain. The team found that estrogen has a direct effect on the brain. In Their experiment, were the resource persons Rats repeatedly exposed to a specific tone, That Had no consequence linked to it. In their experiment, rats repeatedly exposed to a certain tone that has no consequences associated with it. Some Rats after exposure began ignoring the tone Because They Used to it were the resource persons. After several exposures mice began to ignore the tone because they are used to it. The Researchers then linked the tone with a different stimulus. The researchers then connecting tone with a different stimulus. Results showed That Rats with higher levels of estrogen stores much longer to form the association Than Rats with low levels of estrogen. The results showed that mice with higher levels of estrogen may take longer to establish the relationship of the mice with low levels of estrogen.

    "We only observed this effect in adult female Rats," says Brake. "We only observed this effect in adult female rats," said Brake. "This and our other estrogen Findings indicate That directly effects the brain, Perhaps by interfering with brain signaling molecules. Our study helps clear up the controversy about the effects of estrogen, the next step is to look at how this occurs." "These and other findings we show that direct estrogen effects of the brain, possibly by disrupting the molecular signals the brain Our study helps. Clarify the controversy regarding the effects of estrogen, the next step is to see how this happens."
