A man had a heart attack and died while having his brain waves measured. The data was eye-opening.
Death remains a very difficult topic for scientists to study. While there are some reports of near death experiences (NDEs) or people being revived after being declared dead, we've never been able to definitively confirm what happens beyond the grave. Further complicating things, death is often either sudden and unexpected, or a slow and drawn-out process. It's hard to get accurate readings and measurements at the exact moment someone passes away.
However, in 2021, researcher Dr. Raul Vicente and his colleagues at the University of Tartu, Estonia, became the first people ever to record the brainwaves of someone in the process of dying, and what they’ve come to realize should be very comforting to everyone.
“We measured 900 seconds of brain activity around the time of death and set a specific focus to investigate what happened in the 30 seconds before and after the heart stopped beating,” Dr. Ajmal Zemmar, a neurosurgeon at the University of Louisville, US, who organized the study, told Frontiers.

Fascinatingly, the discovery was a complete accident.
The patient who died while having his brain waves measured was 87 years old and had epilepsy. While researchers were studying his brain to learn more about the condition, the man had a heart attack and passed away. “Just before and after the heart stopped working, we saw changes in a specific band of neural oscillations, so-called gamma oscillations, but also in others such as delta, theta, alpha, and beta oscillations,” Zemmar said.
The findings were so special and rare because the man just happened to be hooked up to machines that could measure his brain waves; a miraculous coincidence.

The different types of brain oscillations that occurred in the patient before and after the heart attack were associated with high cognitive functions, including dreaming, concentrating, memory retrieval, and memory flashbacks.
Therefore, it’s possible that as the patient was dying, they had their life flash before their eyes. What an amazing and comforting experience right before leaving this mortal coil.
“Through generating oscillations involved in memory retrieval, the brain may be playing a last recall of important life events just before we die, similar to the ones reported in near-death experiences,” Zemmar speculated. “These findings challenge our understanding of when exactly life ends and generate important subsequent questions, such as those related to the timing of organ donation.”
The positive findings line up with reports of NDEs and first-hand observations from hospice workers. Medical workers who work with dying folks report they often have visions of visitations and conversations with deceased loved ones, almost as if those relatives and friends are preparing to guide them over to the other side. Many people who have been declared dead and lived to tell the tale, or suffered an extreme NDE, report feelings of calm and peace rather than fear and pain.
How long are people conscious after they are technically dead?
Science has found that people can remain conscious up to 20 seconds after they are declared dead. Even after the heart and breathing have stopped, the cerebral cortex can hang on for a little while without oxygen. So, some people may experience the moment when they hear themselves declared dead, but they aren’t able to move or react to the news. In cases where someone performs CPR on the deceased person, the blood pumped by the compressions can temporarily keep the brain alive as well.

Although the experience of death will probably always remain a mystery, we should take solace in the idea that, in many cases, it may not necessarily be a miserable experience but an ecstatic final burst of consciousness that welcomes us into the great beyond. “Something we may learn from this research is: although our loved ones have their eyes closed and are ready to leave us to rest, their brains may be replaying some of the nicest moments they experienced in their lives,” Zemmar concludes.

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.
