Fascinating study suggests there is no such thing as a "male" or "female" brain
It's a great reminder that gendering activities and behaviors is a bunch of bunk.
Are we more alike than we've been led to think?
Have you ever heard that women are "hardwired" to have better memories?
Or that men are "naturally" better at navigating?
Sure, they're just stereotypes, but they're coming from somewhere. And for a long time we've been led to believe that men's and women's brains are fundamentally different, so why couldn't blanket statements like these hold some truth?
British neuroscientist Gina Rippon, Emeritus Professor of Cognitive Neuroimaging at the Aston Braine Centre, Aston University and noted speaker on the subject of sex differences, offered a different idea in 2014. She believes these patterns are acquired through environmental factors—a woman could become great at multitasking because society expects her to be better at it, for example—not because of any innate wiring in her brain.
According to a 2015 study, research suggests her claims are correct.
A team led by researchers at Tel Aviv University in Israel recently concluded that there is no consistent difference between male and female brains.

The team, led by behavioral neuroscientist Daphna Joel, analyzed the MRI scans of 1,400 individuals, mapping things like gray matter (gooey stuff that handles sensation, emotion ... pretty much everything), white matter (the gooey stuff that carries messages between areas of gray matter), and a host of personality traits along the way.
What did they find?
That it's pretty dang rare for a given brain to demonstrate only male or female characteristics.
So next time someone says to you, "Women's brains do this" or "Men's brains behave like this," feel free to call B.S.
The plain truth is that our brains flat out can't be separated into two distinct gender categories.
Our brains, the researchers say, are more like "mosaics" — wonderful mixtures of the traits we usually associate with men or women.
That's not to say the study found no differences between the brains of men and women, but rather that a brain consisting of almost all male or female features was pretty uncommon, and that it'd be really tough to tell if a person were biologically male or female just by looking at their brain.
Yes, on average there are certain differences in brain size, connections between hemispheres, size of the hippocampus or amygdala.
But this particular study found you couldn't make any concrete predictions about how a person's brain would look or function just based on their biological sex.
Joel summed it up in a follow-up publication in 2021:
"Although there are group-level differences between men and women in brain structure, most brains are composed of unique mosaics of brain features, some in a form more common in women compared to men, and some in a form more common in men compared to women," she wrote.
"Moreover, the brain architectures typical of women are also typical of men, and vice versa... Sex category provides little information on an individual’s specific brain architecture or on how their brain is similar or different from someone else’s."
It's a great reminder that gendering activities and behaviors is a bunch of bunk.
If you're not looking at an individual person holistically for the things that make them them, you're doing it wrong
Better yet, The Washington Post writes that these findings are "a step towards validating the experiences of those who live outside the gender binary.

It's just more evidence to support the idea that the biological "parts" you're born with don't really tell us much about who you are.
Turns out that what's inside is much more fluid and malleable than we ever imagined.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
