New Feature! Productivity Software!

Da Feature: Caught this on TechRIVET (awesomeness glazed in a sweet html sauce). Windows Live! Translate makes reading DNI in your native language a snap, which is a good thing because I no speak-o the funny-o languages-o. To the right you'll see a drop down. Click it, select your language and off you go.

Of course, you can always use Google Translate and bookmark the site in your native tongue as well. For example, here I am in Italian!

Da Productivity Software: While we're on the topic of Windows Live! Here's a nice organization/productivity tip. Sign up for FolderShare, another Live! service. Works on PCs and Macs. You basically set up a syncing relationship between specific folders on a several computers, run the application in the background, and voila! Your folders are kept auto'magically' synchronized. I love it love it love it. I write a couple new lines of code, download a new paper or two, and save meeting notes on my laptop, and within seconds, they are on my desktop. Yesterday I added a new lines of code to a MatLab script, saved the file, logged into my desktop PC using VNC, and the new version was waiting for me, ready to run.

The only drawbacks are:
A) You have to be running the program (very low memory and cpu footprint - I leave it on even when I play online games). You can close it, but if you edit the same file on both computers while the program is off it will keep two copies of the file renamed in the same folder.
2) There is a limit to the number of folders you can sync, and that limit is pretty low. Somewhere around 8. As far as files, no idea. I'm syncing my "papers" folder, which is 1,200 documents. 2GB file max size.
III) You can't sync some 'special' folders, like your music folder. They basically are making sure this remains a productivity app, and not a music sharing service.
v.4) I don't think transfers are encrypted.

Once installed and running, though, you can access any file on either PC from a browser (if you have the password). You can also invite others to download share files, though they need the software installed (it's free and sign up is 30 seconds). You can also set each folder to sync automatically or on demand.

Another nice bit of software is SyncBack, for offline syncing. The setup is a little long, because it has a million options that's you'll read about when you go through the first folder setup, but you have total control of everything (plus an easy wizard). I use this for syncing to my portable drive and flash drive. It can be set up to sync everything in one click. Oh yeah, the SE version is $30USD (what i that now? .02 Euros?), but the freeware version is great (and spyware/adware free). (PC only)

And last, but not least, for those 'sensitive' files, there's TrueCrypt. Free and powerful. You can create virtual volumes, encrypted partitions, and the the options are mind boggling. All I know is that you'd have to run all the world's computers for 3,000 years to get at my data files. I'm sure I won't care by then. Open source and stable. Using the entirely encrypted drive option is a little finicky and if set up wrong you'll find yourself reformatting in order to make it more usable. I did that, so just think about how you'll use it. For instance, if the whole drive is encrypted, then you always have to have a system with the software installed, or a flash drive with it. You can also copy a lightweight version to the drive with an encrypted file so that the software is accessible on any PC.

I have found that the best blend of security and usability is to leave the drive formatted as by your PC and create an encrypted virtual volume, which appears as a file on the drive. Keep the lightweight version copied to the drive somewhere and leave a little room for less sensitive files you access regularly. The downside is that if the drive is stolen, people can see that there's something special on the drive, because you have that huge honkin file. But, they will be unable to access whatever is on that virtual volume. Basically, it's always more secure to make it look like there's nothing out of the ordinary, but sometimes that isn't practical.

Couple quick notes: Remember that FAT has a low max file size (4GB?), and your volume will essentially be a file on the drive. NTFS isn't natively supported on Macs or Linux, but support can be 'added'. There have been some reports that the current ways of writing to NTFS from either can cause data corruption, but reading should be fine. ext3 isn't supported on Windows, though ext support can be added (don't worry about ext2 versus ext3 - they are compatible with each other (ext3 adds journaling)). I use Ext2FSD for messing with my Linux partition from Windows Vista without any problems. For reading a Mac drive, you'll have to shell out for something like MacDrive, which is obnoxious in general. Yes, it works, but why can't Apple jsut play nice with the other 95% of the world? And why can't Microsoft just release the some sort of NTFS spec? (PC and Linux)

And last but not least. Everyone has a flash drive now. So why not install some of your favorite apps on it, so they're always available? PortableApps has a nice package of free software. Various torrent sites also have portable-ized pay-for apps (like MS Office and Norton). Just FYI. And here's some love for you Mac users.

Required reading

I think I mentioned it here before, but everyone in BCI should read The Diving Bell and the Butterfly. Phil Kennedy made me read it back during my days and Neural Signals Inc, and while it isn't particularly stirring or eloquently written, the time you take reading it forces you to take the perspective of a locked-in patient. Looks like they have made a movie out of the book, and Slate has the review (spoiler: the reviewer liked it). (IMDb link) Netflix subscribers can save it to their queue so that it is added when available on DVD (I just did).

SNL does BCI

Brain in a Vat found a BCI related short from Saturday Night Live. I particularly like the neural probe they use.

In da newz

Ah vacation. So nice. Here's what hit my radar the past few days...

The technique used by Dr Kuiken at Northwestern for control a robotic limb has been turned on its head, and used to supply touch sensation. Place some haptic sensors on the artificial arm, wire them up to various DRG afferents/efferents, and supply a little juice. (2nd report here.)

MIT, trying to map the whole damn brain. Pffft. Amateurs. Why don't they just stick to wearable motion capture systems?

Ah exoskeletons. How be-est the so rad? (Play the video above.)

DLR had their wares in the news a bit. Yay robots!

Thursday, November 22, 2007


Well, it's Thanksgiving time here in the US, so I am home visiting family in Chicago. The 'rents redesigned their living room with many new tech gadgets that they don't know how to use, so I have alot of work to do.

I'm thankful for all my loyal readers! Awwwww....

Can I call it or what?

Hours after I post my little Sony vs Amazon ebook comparison, admittedly a quick rundown, Gizmodo posts a more formal point by point comparison. Like I said, the Amazon Kindle is nice if you want to just read novels and don't mind paying (ie-have no content already), but the Sony wins out on most fronts.



This was too cool not to post...
first from Guerillartivism


So, I thought I would post a quickie on ebooks. I have, through various sources accumulated thousands of electronic books in various formats (PDF, doc, html, djvu). So, as a technogeek, I have been anxiously awaiting a nice ebook reader that it light and powerful. There have been a couple players tat have entered the market int he last few months, so I thought I would post some quick impressions.

First, the big news maker today is the Amazon Kindle. It looks slick, has a keyboard and neat-o bookmarking and high lighting slider. It ieven has built in EVDO, so yo can buy books directly over the ether for anywhere from $1 (for free Gutenburg works) to $10 for new releases. There's even the ability to upload you own books and convert them to the native format. AND you can submit your own work and even blog (ahem!) to be downloaded via the internal RSS reader. Also, there's an SD expansion slot. 30 hours of reading per charge, using epaper/eink technology.

Downsides? A) Proprietary format with a charge to convert it. Yuck! B) Only SD, but the newer high density version. C) Version 1.0 - who knows what bugs will turn up, or if it will catch on and be viable in a year.

And second, the Sony Ebook reader PRS-505 - the second ebook reader from Sony in a year. New, and improved digital ink for faster page turns (big problem with the old version), MS Pro Duo for expansion, RSS reader and podcast support (mp3 playback, same as the Kindle), multiple formats (PDF, DOC, TXT, RTF), integrated cover, smaller profile, no keyboard.

Downsides? No html, no wireless, must purchase from Sony ebook store for purchased materials.

So, which is the better bet? If you have a big collection, like me, the Sony ebook reader is obviously better. You don't have to pay to convert, you can just throw everything on a memory stick, and is a more 'open' option. Plus it is a slightly more mature platform. If, however, you want to use this as a regular, everyday reader, the kindle might be the better bet. Purchasing is quick and easy, it supports a more community driven approach, and offers a much larger purchasing selection.

Just something to think about. Ebook readers are really starting to look appealing, and these are the two big players. It is probably worth waiting for the next generation before pouncing, but I might try to grab one for review at Digital Trends (I'll post here if I do).

Being heard

Phil Kennedy's work is in the news again. He's been working on using his Neurotrophic Electrode to decode phonemes from Broca's area of a locked-in patient. He did have a number of posters at SfN (right next to mine, too), and the work seems to be moving along steadily. Having talked with him, I know his philosophy is to write papers only when there is a major, major finding, but I would like to see a few technique or preliminary result papers in a peer reviewed journal, like J Neural Engineering. Still, I'll always cheer on the guy that just forges ahead, blazing a path for others.

Unfortunately, the article is at New Scientist, which requires a subscription, which I don't have, but there is a BBC report as well.

The Neurotrophic Electrode is something Phil developed and has been used in several locked-in patients. When I worked with him, we were focused on ALS (Lou Gehrig's Disease) and spinal cord injury (SCI), and implanting MI. The electrode is essentially a glass cone with a bit of sciatic nerve and neurotrophic factor that is just pushed into the cortex. The damage causes neurons to sprout new processes, which are attracted to the trophic factor and grow through the cone. There is no information on the types of cells attracted to the trophic factor, and while units are seen after a couple dozen weeks, the identity of the cells is unknown. While the cone tip is lined up to grab pyramidal cells, the patients need a 'warm up' period in order to activate the cells, which is somewhat suspicious. Other studies using traditional electrodes show instantaneous control, and the fact that a warm up period is necessary could mean that what is actually being grabbed are ascending cholinergic fibers from the RAS or possibly local interneurons active during learning. Either way, information about the associated function is still present, but some basic histology showing more than myelinated fibers in the cone are really needed. Just a few thoughts that I've had since leaving...


Shelley over at the Retrospectacle pointed out that the above confocal image of the cochlea won 4th place in the Olympus Bioscapes Digital Imaging Competition. 1st Place was the Brainbow (which is my current wallpaper on my desktop PC), but I actually like this more. I just wish they would post some nice, high-res versions (like 1920x1200 or 1600x1200). I had to piece the Brainbow one together by hand from the study pdf.

Two upcoming events

I wish I could go to both, but I just don't have time...

First, back in Rome, Italy, there is:
NEUROREHABILITATION AND ROBOTICS. Changing environment to train the function, Dec 13-14. I couldn't find a site that linked directly to the program I received, but here is the Children's Hospital it is associated with.

- I'll be the jerk to say it. Please run titles past native English speakers. This title makes no sense, but I think we get the idea, kinda. Is this supposed to be changing the function of the environment by changing said environment, or changing the environment to change some other 'function'? I think the idea is changing the user's environment such that it assists techniques unique to neurorehabilitation. Either way, it would be nice to get back to Italy, but there's no way I'll be able to make it.

Next, in Naples, FL, there is:
The Neural Control of Movement Society meeting, April 28-May 4 (abstract submission open now)

- I might try to go to this one, but we'll see.

TMR going far

And last one for tonight, Natalia pointed out that Dr. Kuiken's work in Chicago has been in the news again, thanks to some advancements that led to a J Neurophys paper. You'll remember the work (targeted muscle reinnervation) from the big media blitz a couple years ago.

Long story short, they reroute nerves that were going to an amputated limb, to muscles on the chest, side, and abdomen. Patients think about moving the non-existent limb, causing the fibers to fire, thereby eliciting a EMG detectable twitch of the new target muscle. That activity is then translated into movement of a robotic arm. The new paper discusses nerve targets, and more electrodes, making movement detection 95% accurate for 16 movements.

Paper found here.

Exoskeletons and love

BoingBoing has a short story about finding exoskeletons and finding love... awwww. Cool part is that it is based on an actual exoskeleton project at GE back in the 60's.

BoingBoing, and the story.

B2B v2: Brain To Bot

The EU has been hearing the call of BCI, and upping the funding for non-invasive systems left and right. One project to make the news this last week is the Brain2Robot initiative at the Frauenhofer Institute and Charite hospital in Berlin. Not much too new to report here, just a new funding source for another collaboration, but worth noting, of course. The new arm to come out of the collaboration should be shown off... oh... today in Dusseldorf.

DARPA's readin my thoughts, man!

Ah DARPA. When will you stop burrowing through my psychic defenses to sap the sweet, sweet nectar of my thoughts? *sigh*

Apparently the defense department financial juggernaut is funding companies like Honeywell, who are working on harnessing the quasi-subconscious precessing detectable by EEG (okay, yes, I know, that's a crappy description, but you get the idea) to automatically weed out or identify visually perceived objects of interest. Not an entirely new idea, the whole process might make it possible, in the absence of reliable image recognition software, the ability to breeze though crime suspect images at 1 per 50 millisecond, or quickly scanning large landscapes in front of analysts target extraction/identification at high speeds.

Sight and sound

Alright, Super Paper Friday will be tomorrow. I don't have the attention span to compile the whole list right now (about 1/3 done). Instead, here are a few stories...

An interesting idea here. Glasses that have embedded microphones and with attached hearing aids which amplify sounds that the wearer is looking toward and reduce background noise. Not BCI, but neat-o concept. (@ Medgadget)

Again, not BCI, but interface-y, the new JSF (Joint Strike Fighter) helmet prototype "augments skills and the senses". That's all anyone is saying right now. That and that it makes everyone pee themselves in fear. (@ Gizmodo)

And lastly, what robot programmers do when they get bored...

No time for love, Dr. Jones!

I thought I would be all good and update during SfN regularly. Nope. Not happening. Check back this Friday. Something about the acute liver cirrhosis and information overload...

I survived my poster presentation and only had a few minor hiccups, so I was happy. I was actually kinda hoping to get grilled a little more, which is disappointing. A few great questions were asked and some good ideas about future directions were discussed. It was nice to meet a few of you folks reading, including kids from the Nicolelis and Schwartz labs, CalTech, and a few others that I don't remember the institutions of.

It is kinda strange presenting, at least for me. I switch from slightly awkward research mode into showmanship mode, and during that time, everything is a blur. At one point Leigh Hochberg was watching me present, and having seen Leigh on at least a weekly basis while in 'research mode', it completely disrupted my flow. I got caught switching states back and forth, and it was oddly paralyzing. (Not his fault, obviously. It was just a very strange feeling.)

It was great to see so may people from Brown stop by just to say, "hi!" And it was also nice to see all of you NIH folks as well (though I missed Ilya's presentation because I had my poster at the same time).

Anyhow, enough rambling. Tonight: Dinner, Grad student/Post-Doc Social, Recovery/Notetaking/Brainstorming.

Oh, and the line for the MIT party was just frickin ridiculous. That venue was just too damn small (but nice inside).

I made it!

Look out San Diego! The air here is horrible, btw. You could see all the scorched ground on arrival.
