Elon Musk's brain implant company Neuralink has released a video showing how it has taught a monkey - Pager, a nine-year-old macaque - to play the video game Pong with its mind.The video follows Mr Musk's assertion in February that the company has "a monkey with a wireless implant in their skull with tiny wires" that it uses to play video games. Neuralink Corporation, which Elon Musk owns alongside his SpaceX and Tesla businesses, previously claimed to have implanted coin-sized wireless sensors inside the brains of two pigs, describing the sensors as "a Fitbit in your skull with tiny wires".

Study: Some general anesthesia affects region of brain responsible for memory

Study: Some general anesthesia affects region of brain responsible for memory

Health
April 1 (UPI) -- Different general anesthetics used during surgical procedures cause chemical changes in patients' brains, affecting memory, a study published Thursday by PLOS Biology found. Three commonly used combinations of anesthetics, tested on mice, all changed brain activity in the hippocampus -- the region of the brain responsible for memory -- compared to "wakefulness," or not being under anesthesia, or natural sleep, the study showed. Advertisement All anesthetics tested in the study affected the stability of synaptic connections between brain cells in the hippocampus. Two of the three combinations also caused retrograde amnesia, a form of memory loss impacting events occurring immediately before surgery, the researchers said. "Anesthetic procedures are among the safest medical...

Mysterious brain disease killing bald eagles traced to unknown cyanobacterium

Science
March 25 (UPI) -- North America's bald eagles, once severely threatened by DDT exposure, have rebounded dramatically over the last 50 years. In pockets of the American South, however, scientists have found local eagle populations suffering from outbreaks of a mysterious neurodegenerative disease, called avian vacuolar myelinopathy Advertisement Now, nearly 30 years after an outbreak of AVM killed hundreds of eagles in Arkansas, scientists have traced the origins of the deadly disease to a previously unknown cyanobacterium that grows exclusively on an invasive aquatic plant. The revelation -- detailed Thursday in the journal Science -- was made possible by a series of vital breakthroughs, and a fruitful collaboration between scientists in Georgia and Germany. Several years ago, a group of...

Study: Mixing brain, nervous system-related drugs risky for dementia patients

Health
March 9 (UPI) -- Older adults who take three or more drugs for dementia or its complications could accelerate memory loss and declines in thinking ability as a result, according to a study published Tuesday by JAMA. Despite this risk, one in seven adults with dementia in the United Stated who is older than 65 and lives outside of a nursing home takes three or more drugs to treat dementia or related disorders, such as depression, the data showed. Advertisement This so-called "poly-pharmacy," or taking multiple prescription drugs, also can raise the risk for injury and death in the elderly, as some of these medications can cause fatigue, weakness and delirium. "Dementia comes with lots of behavioral issues, from changes in sleep and depression to apathy and withdrawal, and providers, patien...
