Conjoined twins with fused brains separated; surgeons practiced for months in virtual reality
Arthur and Bernardo finally get to see each other face to face.

Surgeons prepared to separate 3-year-old conjoined twins in Brazil using virtual reality.
The things human beings have figured out how to do boggles the mind sometimes, especially in the realm of medicine.
It wasn't terribly long ago that people with a severe injury had to liquor up, bite a stick, have a body part sewn up or sawed off and hope for the best. (Sorry for the visual, but it's true.) The discoveries of antibiotics and anesthesia alone have completely revolutionized human existence, but we've gone well beyond that with what our best surgeons can accomplish.
Surgeries can range from fairly simple to incredibly complex, but few surgeries are more complicated than separating conjoined twins with combined major organs. That's why the recent surgical separation of conjoined twin boys with fused brains in Brazil is so incredible.
The twins, Bernardo and Arthur Lima, are almost 4 years old and have never seen one another's face. They've spent their lives conjoined at the top of their heads, facing opposite directions. Born as craniopagus twins (joined at the cranium), their brains were also fused together, making their separation extremely complex. According to the BBC, they've been cared for at the Instituto Estadual do Cérebro Paulo Niemeyer (Paulo Niemeyer State Brain Institute) in Rio de Janeiro for the past two and a half years.
Surgeon Noor ul Owase Jeelani is the founder of medical charity Gemini Untwined, which funded the surgery. He helped lead the team of nearly 100 medical workers who worked for months to prepare for the boys' separation, which was one of the most complicated of its kind.
Jeelani told the BBC that it was the first time surgeons in separate countries practiced by operating in the same "virtual reality room" together, wearing VR headsets.
"It's just wonderful," he said. "It's really great to see the anatomy and do the surgery before you actually put the children at any risk. You can’t imagine how reassuring this is for the surgeons. To do it in virtual reality was just really man-on-Mars stuff."
Watch Jeelani explain how they prepared for the procedure:
Prior attempts to separate the twins had been unsuccessful, making the surgery even more challenging due to scar tissue. However, after multiple surgeries that took more than 33 hours collectively, the boys were successfully separated in June.
“It was without a doubt the most complex surgery of my career,” said neurosurgeon Gabriel Mufarrej of the Paulo Niemeyer State Brain Institute, according to EuroNews. “At the beginning, nobody thought they would survive. It is already historic that both of them could be saved."
Jeelani told the BBC that the boys' heart rates and blood pressure were "through the roof" for four days after the surgery—until they were reunited and touched hands.
According to Reuters, Bernardo and Arthur are the oldest twins with fused brains to be successfully separated. They will spend the next six months in rehabilitation.
Congratulations to the Lima family and to the global team that combined dedication, perseverance and the miracle of modern technology to create a brighter future for these young boys.

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
