It's not trivial. The EEG signal at the scalp does not necessarily contain the same information accesible with an implanted microchip. The problem is that by the time you record at the scalp you are looking at activity aggregated across large populations of neurons. Not to mention that signal is filtered and spatially smoothed through the skull. If we could get information about what individual neurons are doing without opening someone's head neuroscience would take a huge leap forward. That technology is more than a couple years off.
What data can you gather from a helmet most likely sitting on hair? Guess what.. you dont get much at all.
Well, its EEG. EEG is a reflection of aggregate neural activity and can be recorded quite easily at the skull. Lab research on controling cursors and whatnot has been done before with EEG, but it is usually pretty crude control that one can gain even after extensive practice. As TFA says, "Anecdotally, the system seems to work best with children and others open to believing in their capability, according to Breen." In other words, the gullible tend to believe they are actually controlling things in the game.
Also, fMRI will never be able to predict intentions in real time due to the hemodynamic lag, and is currently practically impossible to analyze online due technical limitations. What they did was use information which occured before the decision to predict which decision was later made. However, this analysis was done after the decision was made . That is to say, after the scans were over, the data from the few seconds before the decision was found to be predictive of which way the decision went. So it's not like they really knew what was going to happen before it did.
I'd like to see an objective rather than subjective test for depression
Well the problem here is that we are talking about a condition that is defined by subjective feelings. If
I have some objective measure that you are depressed, but you say that you feel great, how could I be right? Also, it's much
cheaper and faster to ask you how you feel rather than to perform an MRI .
Also, while depression appears to be associated with hippocampal deficit, hippocampal problems could occur for a variety of reasons other
than depression.
As others have asked, what exactly is new about this?
From TFA, it seems to me that one of the new aspects of this strategy is:
Basically, the letter is sent to the college or university, and is then forwarded to the student.
So the student gets a letter delivered through the university. It's not clear if some kind of university action is implied or explicity
stated in this letter, or if the universities have agreed to cooperate with the RIAA. Either way I bet
getting the university to communicate with the student is a way of providing additional leverage. Perhaps now you are not only
threatened with financial damage but with your educational status being revoked?
The document states that the tests were done on a Dual 2.8Ghz Dell Dimension workstation, and a 3.2GHz Dell XPS workstation, a dual 2Ghz iMac, and a GHz Mac Pro. No futher details on the hardware is given (RAM?), and while these four systems are listed the benchmarks provide only one set of numbers for each operating system.
Why does nearly everyone on/. assume that every company is out to deceive them? or that every press release (unless it's from Google or Apple) is a marketing lie?
Probably because the information is not coming from an unbiased source. Whenever the supplier of information has a vested interest, it is proper to be skeptical.
The drug is not FDA approved for men. As you can read here, Merck is not legally allowed to advertise it as a treatment for anal cancer. When the studies are done I am sure they will. It's in their interest to have as many people taking it as possible, hence the controversy about the lobby effort.
It's not a cervical cancer vaccine. It's an HPV vaccine.
While you are technically correct, HPV is apparantly responsible for around 90% of all cervical cancer cases. HPV
on its own is not all that much trouble. The real purpose of an HPV vaccine to to prevent cervical cancer, which can be deadly.
No, it's just been passed through the prototype Norwegian Internet Filter. Notice they've tried to cross out all the o's. Just wait till they hit the rest of the alphabet, none of these hate sites will be readable!
But anybody who cares about national security and terrorism should be sobered by what happened in this case: an utter failure of threat assessment. Our ability to survive terrorism is not just reliant on the ability to detect and respond to threats: it's crucial to be able to detect the lack of threats and not respond to them
Discrimination is only the goal when a miss is equal in consequence to a false alarm. I think in the case of terrorist attack it is presumed that a miss (lots of people die) is more expensive that a false alarm (money is lost) and so the bias is adjusted accordingly to avoid missing an attack. This will necessarily result in more false alarms.
Yes, the information for the prediction comes from before the action was made. My point is that the analysis of the data is done after the action is performed. That is, they do the scans, then they feed the data into SPM (and then their pattern recognition algorithm), and try to use the info from before the action to predict the action. I'm just saying that since the analysis is done after the fact, the researchers don't actually know what's going to happen before it happens.
Functional MRI measures changes in blood oxygenation, which are indicitave of changes in neural activity. However, the hemodynamic response
is slow, peaking about 6 seconds after the changes in neuronal firing rates. The decisions described in the article probably happen within milliseconds. The article is short on details, but what they probably did was analyze the data from the decision moment after the fact and see if they could use it to predict the subsequent action. This is different from actually knowing what someone is going to do before they do it, which is something that is practically impossible with fMRI due to the timing issues.
a) Apple intentionally did not release Vista compatible versions of their software so that their iPod/iTunes masses would have a compelling reason to not buy Vista and consider buying a Mac instead.
If that was really their intention, why would they release a temporary fix?
I don't know why Apple's waited this long to even announce that their software doesn't work
They have made no such announcement. As the editor notes, the only relevant tech support article is one that simply lists which versions of Windows each piece of Apple software is supported for. The article is updated when this information changes. It has not been updated to claim Vista support, since they don't promise that yet. This is different from Apple announcing that Vista breaks their software.
Apple is a sponsor of the John Lennon songwriting competition and have provided some of the prizes. Seems
to me like this predates the current trademark agreement, and Apple Records is not involved with this bus as far as I can tell.
The lawsuit accuses Dell of artificially inflating profits "by secretly receiving approximately $250 million a quarter in likely illegal rebate kickbacks payments" from Intel in return for an exclusive deal to purchase Intel's microprocessors, class-action lawyer William Lerach told Reuters.
I can see why hiding such a transaction is illegal. But why is the deal itself illegal in the first place? Why do they need to hide that? Why can't Dell make a deal with Intel to use only Intel chips in exchange for a good price if they want to?
You will note too that Apple chose GSM, the European and worldwide standard, as opposed to CDMA, a primarily NA one, for the phone. Does that tell you anything?
Err... the point of this article was that they went to Verizon first. So we can't say they went GSM to get the Euro market if their first choice was CDMA. What it tells me is that they could could put either technology in the iPhone if they choose to.

No, this absolutely cannot be done at this time. I believe the discussion was hypothetical.

Your link is for last year's report, which did not include Vista. My link is to the newer one.
It is there (pdf link).
I was wondering the same thing.

I was able to find the full report as pdf linked from this page which also summarize the results:

Quite right, thanks for the correction.

I think you're still misunderstanding me.

See what I mean?
Yes, they did. But my point was that they did so after the action was performed.
I think this is misleading.
Functional MRI measures changes in blood oxygenation, which are indicitave of changes in neural activity. However, the hemodynamic response is slow, peaking about 6 seconds after the changes in neuronal firing rates. The decisions described in the article probably happen within milliseconds.

I don't think that's related.
