Is it just me, or does the quote "write polished prose, craft impressive emails, and posts on your favourite sites like LinkedIn, Gmail, Facebook, and more." seem to have an errant comma or three? Perhaps they mean "write polished prose to craft impressive emails and posts on your favourite sites like LinkedIn, Gmail, Facebook and more."
The article says "we used unilaterally amputated monkeys that had undergone therapeutic amputation several years (two of them with 9 to 10 years and a third monkey over 4 years) before they arrived in our lab." It doesn't sound like they were amputated for the study, and the length of amputation is relevant to eventual studies in humans, who may have been missing a limb for a long time.
I think they used electrodes in either "contralateral" or"ipsilateral" motor cortex to study the reorganization of neuronal circuitry that was (ipsilateral) or wasn't (contralateral) controlling an intact arm at the time. The reorganization was different in the two cases.
While people do have brain electrodes permanently implanted to help control Parkinson's disease (deep brain stimulation), having electrodes implanted isn't for the faint of heart!
When text paging was new, a friend of mine was making a presentation when his pager went off with the message "Your fly is open!" A quick check showed his zipper was actually up, and he continued the presentation. A few minutes his pager went off again, this time with the message "Made you look!"
He never did figure out who sent the pages.
I test drove a Model S last month. It goes 0 to 60 miles per hour in 3.1 s with no wheel spin and no noise except the whine of the electric motors. It feels like you're being shot out of a cannon (at least, that's what I think it would feel like to be shot out of a cannon). My regular car is a Shelby Mustang, and the Tesla is much quicker. I'm told the chassis has 22 moving parts, with no oil changes, timing belt changes, spark plugs, etc. If only I could afford one.
