Brain Scanner Records Dreams on Video
Just a few weeks ago, we posted about how brain patterns can reveal almost exactly what you're thinking. Now, researchers at UC Berkeley have figured out how to extract what you're picturing inside your head, and they can play it back on video. The way this works is very similar to the mind-reading technique that we covered earlier this month. A functional MRI (fMRI) machine watches the patterns that appear in people's brains as they watch a movie, and then correlates those patterns with the image on the screen. With these data, a complex computer model was created to predict the relationships between a given brain pattern and a given image, and a huge database was created that matched 18,000,000 seconds worth of random YouTube videos to possible brain patterns. Comparing the brain-scan video to the original video is just a way to prove that the system works, but there's nothing stopping this technique from being used to suck video out of people's heads directly.

WikIT Buzan Online has responded to criticism of a lack of academic studies showing the efficacy of mindmapping with a list of references on this page. None of the papers are linked to there, it's just a plain text list (Why Mr. Buzan? If you claim "The Proof is Here!" But before we look at that list, we need to consider "efficacy of mindmapping" for what? Comments are being added here from time to time, as the papers are read and the conclusions reached extracted.

- StumbleUpon WHY DID THE CHICKEN CROSS THE ROAD? Plato: For the greater good. Karl Marx: It was a historical inevitability. Machiavelli: So that its subjects will view it with admiration, as a chicken which has the daring and courage to boldly cross the road, but also with fear, for whom among them has the strength to contend with such a paragon of avian virtue? In such a manner is the princely chicken's dominion maintained. Hippocrates: Because of an excess of light pink gooey stuff in its pancreas.

8 Things Everybody Ought to Know About Concentrating “Music helps me concentrate,” Mike said to me glancing briefly over his shoulder. Mike was in his room writing a paper for his U.S. History class. Mike made a shift about every thirty seconds between all of the above. Do you know a person like this? The Science Behind Concentration In the above account, Mike’s obviously stuck in a routine that many of us may have found ourselves in, yet in the moment we feel it’s almost an impossible routine to get out of. When we constantly multitask to get things done, we’re not multitasking, we’re rapidly shifting our attention. Phase 1: Blood Rush Alert When Mike decides to start writing his History essay, blood rushes to his anterior prefrontal cortex. Phase 2: Find and Execute The alert carries an electrical charge that’s composed of two parts: first, a search query (which is needed to find the correct neurons for executing the task of writing), and second, a command (which tells the appropriate neuron what to do). Phase 3: Disengagement 1. 2. 3. 4.

Sowa: Semantic Networks John F. Sowa This is an updated version of an article in the Encyclopedia of Artificial Intelligence, edited by Stuart C. Shapiro, Wiley, 1987, second edition, 1992. Most of the text from 1992 is unchanged, but more references and updates have been added. A semantic network or net is a graph structure for representing knowledge in patterns of interconnected nodes and arcs. What is common to all semantic networks is a declarative graphic representation that can be used to represent knowledge and support automated systems for reasoning about the knowledge. Definitional networks emphasize the subtype or is-a relation between a concept type and a newly defined subtype. Network notations and linear notations are capable of expressing equivalent information. 1. The oldest known semantic network was drawn in the 3rd century AD by the Greek philosopher Porphyry in his commentary on Aristotle’s categories. Figure 1. Figure 2. Every truck is a vehicle.

Seeing in the Dark & SEEDMAGAZINE.COM Credit: cliff1066tm. Patient TN was, by his own account, completely blind. Two consecutive strokes had destroyed the visual cortex of his brain, and consequently, his ability to see. It is not uncommon for stroke patients to suffer brain damage, but the case of TN — referenced by his initials, the general practice in such studies — was peculiar. Known as selective bilateral occipital damage, TN’s unusual injury made him the subject of much interest while recovering at a hospital in Geneva. To further test the extent of TN’s abilities, researchers from Tilburg University in the Netherlands devised a simple yet decisive experiment: an obstacle course. TN’s rare condition is known as blindsight. The researchers explained that TN’s success indicates that “humans can sustain sophisticated visuo-spacial skills in the absence of perceptual awareness.”

This is awesome News, Videos, Reviews and Gossip - io9 The Good: AMAZING effects and character design! The battle droids actually *looked* like devices built for live combat situations—heavily-armoured, heavily-ARMED, and just...heavy! The Bad: 1) WHEN will people finally drop the completely stupid "careful withdrawal of consciousness from virtual environment" trope? The rig on the interrogator's head is clearly a simple noninvasive magnetic-resonance device stimulating parts of his brain. 2) If a battle bot has some way of overloading its batteries or onboard generator to generate an EMP, IT WILL FRY ITSELF IN THE PROCESS. I know, I know, I'm a nitpicking geek...but, really, what's the excuse for complete scientific illiteracy in so-called "sci-fi" film-making?

Novak & Canas: Theory Underlying Concept Maps Concept maps are graphical tools for organizing and representing knowledge. They include concepts, usually enclosed in circles or boxes of some type, and relationships between concepts indicated by a connecting line linking two concepts. Words on the line, referred to as linking words or linking phrases, specify the relationship between the two concepts. Figure 1. (click on an image for a larger view) Another characteristic of concept maps is that the concepts are represented in a hierarchical fashion with the most inclusive, most general concepts at the top of the map and the more specific, less general concepts arranged hierarchically below. Another important characteristic of concept maps is the inclusion of cross-links. A final feature that may be added to concept maps is specific examples of events or objects that help to clarify the meaning of a given concept. The question sometimes arises as to the origin of our first concepts. Figure 2. (click on image for a larger view)
