    A clump of human brain cells can play the classic computer game Doom. While its performance is not up to par with humans, experts say it brings biological computers a step closer to useful real-world applications, like controlling robot arms.

    In 2021, the Australian company Cortical Labs used its neuron-powered computer chips to play Pong. The chips consisted of clumps of more than 800,000 living brain cells grown on top of microelectrode arrays that can both send and receive electrical signals. Researchers had to carefully train the chips to control the paddles on either side of the screen.

    A large, 20-year trial showed that speedy cognitive exercises could reduce the risk of Alzheimer's disease and other types of dementia. The question is, could these tasks be adapted into video games?

    Specific cognitive training has 'astonishing' effect on dementia risk

    A type of cognitive training that tests people's quick recall seems to reduce the risk of dementia, including Alzheimer's disease

    Cognitive training could arm the brain against the effects of dementia

    Cognitive “speed training” can reduce the risk of a dementia diagnosis by 25 per cent – that’s according to results from the world’s first randomised controlled trial of any intervention against the condition.

    “There was a lot of scepticism about whether or not brain training interventions were beneficial, and to me, [our study] answers the question that they are,” says Marilyn Albert at Johns Hopkins University School of Medicine in Baltimore, Maryland.

    Brain train game may help protect against dementia for up to 20 years

    A large, long-term study found that playing a brain training video game may help protect the brain against dementia for decades. Experts say the findings are the strongest evidence yet that cognitive training can create lasting changes in the brain.

    “It’s very surprising,” said Marilyn Albert, director of the Johns Hopkins Alzheimer’s Disease Research Center. “It’s not at all what I would have expected.”

    The research, published Monday in the journal Alzheimer’s & Dementia: Translational Research & Clinical Interventions, was a long-term follow-up of the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) trial.

    Specifically, participants who did up to 23 hours of a specific type of cognitive training called speed training over a three year period were found to have a dramatic 25% lower risk of developing Alzheimer’s and other types of dementia over a 20-year follow-up period.

    Woman born with no brain turns 20 in medical ‘miracle’ — told she’d never make it to 5

    A “miracle” Nebraska woman born without a brain defied the odds as her family marked her 20th birthday — decades after parents were told she’d never make it to 5, reports said.

    Simpson’s parents had been told she was a healthy child until a check-up two months later revealed that their daughter had hydranencephaly — a rare condition that left her with just a pinky’s worth of brain matter at the base of her skull, the report said.

    At the time, the Nebraska family were told Alex wouldn’t live past 4 years old.

    “Twenty years ago we were scared, but faith, I think, is really what kept us alive,” Shawn Simpson, Alex’s father, told the TV station.

    Baby born with nearly no brain still alive 20 years later

    LINCOLN, Neb. (KETV/CNN NEWSOURCE/WKRC) — A Nebraska family is celebrating a milestone once thought impossible as their daughter, Alex Simpson, defies the odds 20 years after being diagnosed with hydranencephaly — a rare condition that left her born with almost no brain.

    Her parents, Lorena and Shawn Simpson, said they still remember the day doctors delivered the devastating news.

    “Doctor Davey came in with his nurses and said, ‘You guys need to sit down. This is pretty serious,’” they recalled.

    At the time, they were told Alex likely wouldn’t live past the age of four. But on Nov. 4, Alex celebrated her 20th birthday — a milestone her family calls nothing short of miraculous.
