The immune link between a leaky blood-brain barrier and schizophrenia

For people with schizophrenia and other mental disorders, a more permissive blood-brain barrier appears to allow the immune system to get improperly involved in the central nervous system. The inflammation that arises likely contributes to the clinical manifestations of neuropsychiatric conditions, according to new findings from a team led by researchers from the School of Veterinary Medicine, Perelman School of Medicine, and Children’s Hospital of Philadelphia (CHOP).

Neuralink’s monkey can play Pong with its mind. Imagine what humans could do with the same technology

Anna Wexler of the Perelman School of Medicine expressed skepticism about Neuralink, a company developing brain-machine interfaces. “Neuroscience is far from understanding how the mind works, much less having the ability to decode it,” she said.

Scientists identify the region of the brain associated with risk-taking—and it could explain why some people are more likely to smoke and drink

Gideon Nave of the Wharton School spoke about research he co-authored, which identified areas of the brain linked with risk-taking. “We find that we don’t have only one brain region that is the ‘risk area,’” he said. “There are a lot of regions involved.”

Elon Musk to show off working brain-hacking device

Ari Benjamin, a doctoral student in the School of Engineering and Applied Science, said the biggest stumbling block for brain-to-machine interface technology is the complexity of the human brain. "Once they have the recordings, Neuralink will need to decode them and will someday hit the barrier that is our lack of basic understanding of how the brain works, no matter how many neurons they record from,” he said. "Decoding goals and movement plans is hard when you don't understand the neural code in which those things are communicated."
