By Washington University in St. Louis May 28, 2023A multidisciplinary team led by associate professor Hong Chen at Washington University in St. Louis has developed a novel, noninvasive method to induce a torpor-like state in mammals by targeting the central nervous system with ultrasound. The technique, which involves stimulating the hypothalamus preoptic area in the brain, was shown to effectively reduce body temperature and metabolic rate in mice, leading to a state of torpor, which is a natural mechanism used by some…

Elon Musk's brain implant company, Neuralink, says it's gotten permission from U.S. regulators to begin testing its device in people.The company made the announcement on Twitter Thursday evening but has provided no details about a potential study, which was not listed on the U.S. government database of clinical trials.Officials with the Food and Drug Administration (FDA) wouldn't confirm or deny whether it had granted the approval, but press officer Carly Kempler said in an email that the agency "acknowledges and…

Stimulating the brain with magnetic fields can help relieve the symptoms of depression in some people, but scientists haven't been sure precisely why it works. A new study offers some insight: The process reverses brain signals going in the wrong direction.These neural streams of activity going in the wrong direction could also be used as a way of diagnosing depression in the future, according to the team behind the study.Officially known as Transcranial Magnetic Stimulation (TMS), the treatment is non-invasive, can be…

This exciting advancement brings us closer to witnessing a science fiction concept becoming a reality. Inspired by what…

Scientists studying obesity in mice have found a new type of brain cell that boosts appetite, even when the body is satiated for a long time.Neuropeptide Y neurons are the focus of many studies on metabolic syndromes. They are particularly abundant in a part of the brain's hypothalamus called the arcuate nucleus, producing potent neurotransmitters that stimulate appetite and delay feelings of fullness.For many years, only one type of neuron was thought to express neuropeptide Y (NPY), the molecule that gives NPY neurons…

ChatGPT is the most exciting thing happening in tech, and we’ve only just begun to scratch the surface. The generative AI wars have just begun, with OpenAI, Microsoft, and Google at the forefront. Granted, the first two are working together, but they’re still distinct companies pushing different agendas. And I’m not even naming all the other generative AI programs built into other apps and services. But since we’re in the early days of smarter AI, we have to expect errors and glitches. Data accuracy is far…

Leggett told researchers that she “became one” with her device. It helped her to control the unpredictable, violent seizures she routinely experienced, and allowed her to take charge of her own life. So she was devastated when, two years later, she was told she had to remove the implant because the company that made it had gone bust. The removal of this implant, and others like it, might represent a breach of human rights, ethicists say in a paper published earlier this month. And the issue will only become more…

Burkhart's device was implanted in his brain around nine years ago, a few years after he was left unable to move his limbs following a diving accident. He volunteered to trial the device, which enabled him to move his hand and fingers. But it had to be removed seven and a half years later. His particular implant was a small set of 100 electrodes, carefully inserted into a part of the brain that helps control movement. It worked by recording brain activity and sending these recordings to a computer, where they were…

Over a decade ago, a cycling accident left Gert-Jan Oskam paralysed after causing him a spinal cord injury. Now, he’s able to stand and walk again thanks to an innovative brain-spine interface (BSI) developed by a team of Swiss neuroscientists. To walk, the brain must send a command to the region of the spinal cord that’s responsible for movement control. But a spinal cord injury interrupts this communication. “Our idea was to reestablish this communication with a “digital bridge”, an electric…
