Catching up

Yeah, I loooove to see "1000+" next to my rss feed subfolders... ugh. Catching up on news items slowly, but going to try to be back at a regular clip this weekend. Prelim done, need to update a few research related doohickies, Mendeley thingamabobs, film project whatsits, and organize all the junk that has been piling up the last couple weeks. Whee! Fun!

As a side note, I love Amtrak. Get there 10 minutes beforehand, no lines, power adapters, leg room, smooth riding, jeez. I think I am a total rail convert. No worrying about laptop batteries running low or turning them on and off during take off and landing. Just though I would share the love.

One more thing...

Papers feed is live, and has been added to the list on the right. Or click here.

A week away

So, I underestimated the amount of work leading up to my prelim defense, and going to start my little break now-ish. It isn't the prelim work as much as the other stuff, like my little Thunderbird on a USB stick took forever to configure perfectly, and was then corrupted by an old version of TrueCrypt hiding on one of my computers. *poof* All that work disappeared. Ugh. Not sure how to handle that now, but might have to think up a little hack to make it work properly.

In the meantime, here are a few stories...

60 Minutes covered DEKA on Sunday. Thank you to the 20-ish people that let me know about it, including my parents. They're silly. They still live in a world where missing a TV show means you have to wait for the rerun. Video clip is up on the 60 Minutes site.

This best computer interfaces story is a trip down memory lane.

Pravda has a very vague and almost not worth reading article on a Russian BCI group.

The Boston Globe discusses some of the hurdles of setting up an implantable BCI project, and chronicles the situation over at the now defunct Cyberkinetics. I don't want to say anything about the project that could anger one of the 14,000 government institutions regulating aspects of it (kidding on the number btw), so I will point to here (yes, the page is in a very very early alpha state).

And some sort of licensing setup for ECoG algorithms has been setup with a company called Neurolutions. (Really? Neurolutions? Have we gotten to the point where all the good brain related names are taken? Even DNI, which was a 3am, caffeine-induced hyper-mania induced naming beats the snot out of that.)

I could bring myself to watch this clip, but here's the title:
"Robotic baby seal has healing powers" - CNN (also known as, "We fired out entire science department, but what could go wrong?" News)
Video clip. Be sure to get the tshirt, too.

Slow goin' and syncing madness

Just a quick note (again) that things over here are changing, which always puts the strain on DNI. Right now my big issue is that all my email is being aggregated by GMail with another account, so I have to log in and out to get to my rss feeds and DNI mail. Plus, a little side project knocked out this weekend + the beginning of the week. Sooooo... sorry about the lag. Also, this Wednesday through next Wednesday will be a brief break, since I'll be preparing and presenting my prelim. Just giving fair warning.

I'm thinking of moving to Thunderbird 3 on a USB key for email, then Neuvasync for iPhone contact/calendar syncing. I'd have a TrueCrypt encrypted file to contain it all. The big problem is that TB, and all email clients for that matter, can only move messages to a single folder, which is picked up by GMail as a tag. In GMail you can have multiple tags, and I would like to be able to move seamlessly between TB and GMail. Poopy. Someone needs to make a GMail tagging add-on for TB. Anyhoo....

Also, if you have a LinkedIn account, there is a BCI group that you might find worth checking out.

House episode and SPF note

Hulu says that the BCI episode of House will be up April 7. Pirate Bay says it's been up since a year before it aired. :D No, I'm not encouraging pirating, but ya see the problem here? Eh, I can't stay mad at Hulu. They just added all the episodes of Voltron. Activate interlocks! Dynatherms up! Megathrusters go!

I wanted to get SPF out today/yesterday but I have been swamped with work. I will probably do one final change to the rss feeds (I know, I know, sorry). I can't keep track of which tag I'm supposed to use for papers, so I will add a Papers feed and just put all of them under the Papers tag. No papers in any other feeds unless they are very important/interesting. In the meantime, you could just search the feeds for "Pubmed" or "journal" and be able to get the bulk of what I will be aggregating into SPF.

BCI on House

If you love House, that great TV show starring Hugh Laurie as the cantankerous Dr. Gregory House, you should have noticed that they used a BCI in the most recent episode (season 5 episode 19). I was waiting for Hulu to have it up, but got enough emails and calls that I thought I would mention it today. Typical TV BCI, EEG-ish and mystical in operation, but the episode was pretty well done, with internal dialogue from the patient and no spelling of words as fast an able-bodied person could say them, but got a little cheesy. Still, this is an example of where an EEG system would make more sense than an implanted one. Cursor up for yes, cursor down for no.

Neuroscientists put out

I'm going to let you in on a dirty little secret: neuroscientists are total players. Ha ha, right? Ignore that sample size isn't mentioned and check it:

(thepHtest, thanks Vania)

Honda: Our in-house research can't read

Apparently, Honda has decided that they are the first to use a BCI (NIRS and EEG combo in this case) to control a robot (video here-and, oh, is it worth it). Not the first to use this technique, but the first to do it, ever. Okay, let's pretend that the Fetz 1969 experiments drove a 'device' instead of a robot (I'm not even sure how far back a device driven by surface electrode input might have been), but this is massively misleading. Sure this is just a stupid company statement, but Google "first robot controlled by a BCI" in two days and this crap will be the #1 result. *facepalm* I'm sure I can't really have an impact on such a large corporation's ridiculous press statement, so instead enjoy this video of ASIMO falling down stairs:

Thanks Katie for the heads up.
