How does the human brain construct intelligent behavior? Computational models have proposed several mechanisms to accomplish this: the most well known is “Hebbian learning,” a process mathematically similar to both principal components analysis and Bayesian statistics. But other neural learning algorithms must exist – how else could the brain disentangle mere correlations from true causation?…

Well, it’s not quite as erotic as it sounds, but they could break the ice on more than a few Valentine’s dates. Hayward’s new article in Brain Research Bulletin describes all known tactile illusions. Some can be tried easily at home, but can work better when your gaze is averted and if someone else is…

Caffeine is the most widely used stimulant in the world, but few use it to maximal advantage. Get optimally wired with these tips.

We often assume that true understanding is conveyed through spoken speech rather than gesture, but new research shows that “talking with your hands” can not only reveal different information than spoken language, it can be both more correct and yield better learning.

When do we learn to imagine the future, and how is that capacity based on imagining the past? How does this kind of “mental time travel” develop? Lagatutta’s recent article in Child Development tracks the development of this impressive feat, thought by some to be uniquely human.
