The largest functional brain imaging study to date tells us something we might not have expected and it’s quite interesting. Could the brains of women be more active than those of men?
The study titled ‘Gender-Based Cerebral Perfusion Differences in 46,034 Functional Neuroimaging Scans’ was published in the Journal of Alzheimer’s Disease and goes over just that. It was determined that the brains of women were much more active on a significant level in quite a few areas and helps us to better understand gender-based brain differences. While you might not think this is a significant find, it is something that can lead to so much more in the future as research continues to be done.
According to JAD in a statement, the lead author of this study psychiatrist Daniel G. Amen said as follows in regards to their findings:
“This is a very important study to help understand gender-based brain differences. The quantifiable differences we identified between men and women are important for understanding gender-based risk for brain disorders such as Alzheimer’s disease. Using functional neuroimaging tools, such as SPECT, are essential to developing precision medicine brain treatments in the future.”
You see, for this study researchers analyzed the brains of 119 healthy volunteers and 26,683 patients with a variety of psychiatric conditions. These conditions ranged from mood disorders to brain trauma and well, most things in-between. Understanding the gender-based differences when it comes to our brains will better help us understand why different brain disorders and so forth affect men and women differently.
Results: Compared to males, healthy females showed significant whole brain (p < 0.01) and ROI increases in 65 baselines and 48 concentration regions (p < 0.01 corrected). Healthy males showed non-significant increases in 9 and 22 regions, respectively. In the clinical group, there were widespread significant increases in females, especially in the prefrontal and limbic regions, and specific increases in males in the inferior occipital lobes, inferior temporal lobes, and lobule 7 and Crus 2 of the cerebellum. These findings were replicated in the subset of 11,587 patients with the effect of diagnoses removed. Conclusions: Our results demonstrated significant gender differences in a healthy and clinical population. Understanding these differences is crucial in evaluating functional neuroimaging and may be useful in understanding the epidemiological gender differences among psychiatric disorders.
This all boiling down to, yes, the brains of women are a bit more active than the brains of men. For more information on this please feel free to check out the video below. What do you think about all of this?
