There were more pecks at strangers than at companions in both L- and D-chicks [test condition: F(1, 34) = 16.313, p < 0.001; hatching condition: F(1, 34) = 0.050 (not significant, or “ns”); test × hatching: F(1, 34) = 0.300 (ns)].

LongboatPrusa translations: Brazilian portuguese Longboat Prusa Release status: Working A better way to remember Scientists and educators alike have long known that cramming is not an effective way to remember things. With their latest findings, researchers at the RIKEN Brain Science Institute in Japan, studying eye movement response in trained mice, have elucidated the neurological mechanism explaining why this is so. Published in the Journal of Neuroscience, their results suggest that protein synthesis in the cerebellum plays a key role in memory consolidation, shedding light on the fundamental neurological processes governing how we remember. The "spacing effect," first discovered over a century ago, describes the observation that humans and animals are able to remember things more effectively if learning is distributed over a long period of time rather than performed all at once. Explaining this observation, the researchers found that the spacing effect was impaired when mice were infused with anisomycin and actinomycin D, antibiotics which inhibit protein synthesis.

How journalists use Twitter I've tweeted three times in the last 12 days. Three. Yet I'm on Twitter constantly. I have 15 active columns on TweetDeck. How birds use their eyes: Opposite left-right specialization for the lateral and frontal visual hemifield in the domestic chick Open Archive Abstract Recent evidence has demonstrated that, in animals with laterally placed eyes, functional cerebral asymmetry is revealed by preferential use of either the left or right eye in a range of behaviors (birds: 1, 2 and 3; fish: 4 and 5; reptiles: 6 and 7). These findings pose a theoretical problem. It seems that there would be disadvantages in having a substantial degree of asymmetry in the use of the two eyes; a deficit on one side would leave the organism vulnerable to attack on that side or unable to exploit resources appearing on one side.

A STUDY OF TAIJI PUSH-HANDS By Xiang Kairen People who practice Taijiquan all know that practicing the form is the "body" (ti), practicing push-hands is the "use" (yong). It "Rewires Your Brain?" Think Again. It seems so archaic: I type with my fingers and I use my hands to drive. Isn't there a better interface than the body? I want devices that can read my mind. “Tim and Eric” directed this lightbulb ad for GE, starring Jeff Goldblum, and it's awesome This commercial for GE Link Light Bulbs starring Jeff Goldblum was directed by Tim Heidecker and Eric Wareheim, bizarro-discomfort comedy performers and directors best known for the Cartoon Network Adult Swim programs “Tim and Eric Awesome Show, Great Job!,” “Check it Out With Dr. Steve Brule,” and “Tom Goes to the Mayor.”

BLOCK DIAGRAM OF THE VISUAL CORTEX IN HUMANS Last Update: July 2009 Rhodonine™ and Activa™: See Citation Page The following figure is presented here at reduced scale (resolution) to accommodate a browser. Block Diagram of the Cortical System in humans, with emphasis on vision. [from Section 15.2] A larger scale version appears in Chapter 15 and is available for download in the Download Files area reached from the Site navigation bar. This figure illustrates how sensory information is fed to the higher perceptual areas of the cortex for evaluation via a series of feature extraction engines.

Massively Parallel Computer Built From Single Layer of Molecules Modern computer chips handle data at the mind-blowing rate of some 10^13 bits per second. Neurons, by comparison, fire at a rate of around 100 times per second or so. And yet the brain outperforms the best computers in numerous tasks.
