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."

A radical new model of the brain illuminates its wiring

Danielle Bassett of the School of Engineering and Applied Science spoke about how neuroscience has led to a greater understanding of the brain’s networks and how to treat a variety of conditions. “Hopefully, with an understanding of the individual differences in the brain, we will have a better lever on how to predict human responses to a particular intervention,” she says, “and then not have to have people go for a year through different kinds of medication before we find one that works for them.”
