Abstract
Brain-machine interfaces hold promise for the restoration of sensory and motor function and the treatment of neurological disorders, but clinical brain-machine interfaces have not yet been widely adopted, in part, because modest channel counts have limited their potential. In this white paper, we describe Neuralink's first steps toward a scalable high-bandwidth brain-machine interface system. We have built arrays of small and flexible electrode "threads," with as many as 3072 electrodes per array distributed across 96 threads. We have also built a neurosurgical robot capable of inserting six threads (192 electrodes) per minute. Each thread can be individually inserted into the brain with micron precision for avoidance of surface vasculature and targeting specific brain regions. The electrode array is packaged into a small implantable device that contains custom chips for low-power on-board amplification and digitization: The package for 3072 channels occupies less than 23×18.5×2 mm3. A single USB-C cable provides full-bandwidth data streaming from the device, recording from all channels simultaneously. This system has achieved a spiking yield of up to 70% in chronically implanted electrodes. Neuralink's approach to brain-machine interface has unprecedented packaging density and scalability in a clinically relevant package.

"Donald Trump's press conference performance in Helsinki rises to & exceeds the threshold of 'high crimes & misdemeanors,' " Brennan tweeted. "It was nothing short of treasonous. Not only were Trump's comments imbecilic, he is wholly in the pocket of Putin. Republican Patriots: Where are you???"
Meeting runs long
Trump and Putin blew past the 90 minutes they were scheduled to spend with only interpreters at their sides on Monday, just hours after the US President blamed US policy for the dismal state of relations between the two countries."

Helsinki, Finland (CNN)
President Donald Trump’s daily coronavirus briefing at the White House, CNN’s Jim Acosta told viewers Monday, produced “the biggest meltdown I have ever seen from a president of the United States.”
Acosta, CNN’s chief White House correspondent, said during a live report with CNN’s Erin Burnett, that “I don’t think a reasonable person could watch what we just saw over the last hour and conclude that the president is in control. It sounds like he is out of control.”
The briefing, in which Trump deflected criticisms of his administration’s response to the spread of Covid-19, included several heated exchanges, and plenty of real-time reaction on Twitter, where the hashtag #PressBriefing was the top political trending topic, followed by #TrumpMeltdown, and even #OMG Trump.
CNN broke away from the briefing to go directly to a correspondent who began fact-checking the president’s claims, in particular his claim that as president, he has “total” authority. The president has frequently deferred to governors, saying response to the spread of the coronavirus is a state matter.
Viewers took to social media to buzz about the briefing, and to call out the on-screen banner writers at CNN. So many people began their tweets with the words “the CNN” that those words also began trending early Monday evening.
At one point during the briefing, Trump played a video many described as a campaign-style message praising the president for his handling of the crisis. CBS News correspondent Paula Reid questioned the president, saying “your video has a complete gap. What did your administration do in February with the time that your travel ban bought you?
The president said “a lot” and then disparaged the highly regarded Reid, saying “you know you’re a fake.”
