While research on how alcohol causes effects in humans continues to take place one after another, the results of another very striking research were shared today. The new research, published in the journal eNeuro, found that alcohol affects the brain activity of men and women differently.
In their new research, the scientists examined the ‘amygdala’, the structure in the brain that plays an important role in motivation and emotional behavior, which is not yet known how alcohol affects. Tests with mice showed that alcohol affected its releases in the amygdala differently in male and female mice, especially after repeated alcohol consumption.
Males showed a significant change, while females did not:
The results showed that, interestingly, the amygdala oscillation in women did not change at all after repeated alcohol administration. The scientists then repeated the tests in mice lacking a subunit of a receptor associated with alcohol use and anxiety that induces characteristics of female network activity in males.
The results showed that alcohol consumption, especially in men, can trigger the amygdala to cause changes in anxious and fearful behaviors. How the amygdala remains unaffected in women is not yet clear.
