The microstructure of white matter – the fatty network of neuronal fibers that transfer information between regions of gray matter – has been found to change with hormonal shifts, including puberty, oral contraception use, gender-affirming hormone therapy, and post-menopausal estrogen therapy.
To address the menstruation gap in our understanding, the team took MRI scans of their subjects during three menstrual phases: menses, ovulation, and mid-luteal. At the time of each of these scans, the researchers also measured the participants' hormone levels.
The results showed that, as hormones fluctuate, gray and white matter volumes change too, as does the volume of cerebrospinal fluid.
In particular, just before ovulation, when the hormones 17β-estradiol and luteinizing hormone rise, the brains of the participants showed white matter changes suggesting faster information transfer.
Follicle-stimulating hormone, which rises before ovulation, and helps stimulate the ovary follicles, was associated with thicker gray matter.
Progesterone, which decreases after ovulation, was associated with increased tissue and decreased cerebrospinal fluid volume.
What this means for the person driving the brain is unknown, but the research lays the groundwork for future studies, and perhaps understanding the causes of unusual but severe period-related mental health problems.

And have they shown this in both men and women?
No comment.
Wonder what this might mean with the regard to use of BCPs...
40+ years of marriage and I could have told you that without dropping big money for this.
“What this means for the person driving the brain is unknown...”
But everybody else on the road knows ALLLLLLLLL about it.
Would you trust a car that lost a quart of oil every month???
(Duck and cover)
LOL! (The voice of experience.)
The scientists just now figured this out?
So proving what most married m3n knew for thousands of years
Not too bright scientists. They have found what we knew was there all along.
Um, I could have given the bottom line to this research without delay, although I would demand to be paid for the years of experience that I have instead of the time I spend on my assessment. I pretty sure I would be less expensive and just as effective.
Yup
I would say the brain of a man at his peak production of testosterone is distinctly different from an older mans who has low T.
Study funded my men whose wives have extreme PMS and live in fear.
oh come on, let it fly....
*snort* never heard that one before.
Rather sounds like “the person being driven by the brain” instead.
Got that from a retired marine I worked with 25 years ago…
It’s a good one.
