Among the cute mistakes that children make, one is to overestimate how much information they can garner through vision. For instance, asked to judge whether they can tell apart two identical-looking, but differently weighted (or different sounding) objects, simply by looking at them, five-year-olds tend to say Yes. Now an intriguing new paper suggests this is an error that we adults fail to completely outgrow.In the second and more persuasive of their experiments, Jessica Wang and her colleagues........

Last evening, while watching people passing by my lane, I realized how lucky it is to be happy and alive. It wasn’t the same with me a few months back. I used to prefer staying alone. I had locked my guitar inside the cupboard. And I had quit my work. Was I in a state of […]

Do your thoughts and feelings have colors? Do you feel red with rage during traffic, or green with envy when your lady swoons over Ryan Gosling? A recent methods paper introduces a very cool technique that allows the visualization and measurement of voltage within an excited neuron.

There is a voice in my head. Don't worry it's mine... I think [a story for another time I'm sure], but why is my voice inside my head? What causes me to hear myself while I type these very words, or even better you to hear them in your voice as you read them? Consciousness is a complex and very confusing thing. I think therefore I am? Science has had trouble cracking that nut and philosophy just won't cut it in the realm of neuroscience. [...]... Read more »

In a recent article from Shifman, Levy and Thelwall, internet jokes are found to serve as an important and powerful agent of globalization and americanization. To research the role of internet jokes, they look at the concept of “user-generated globalization”, where internet users are the focal points through which user-generated content (in this case jokes) is translated, customized and distributed across the globe....

In the 2000s, enthusiasm was high that a novel class of drugs would reach the market as blockbuster treatments for psychiatric disorders. These drugs act on receptors for a group of neuropeptides known as tachykinins (or neurokinins). These peptides — substance P (SP), neurokinin A (NkA), and neurokinin B (NkB) — function as neurotransmitters or neuromodulators in the central nervous system, but are quite different from the usual monoamines targeted by current psychotropic medications prescr........

By guest blogger James Coyne.Edgar Allan Poe’s fictional detective C. Auguste Dupin warns against tackling questions that are too complicated to test, but too fascinating to give up. Whether psychotherapy or medication can reduce suicidality is probably such a question. Particularly if we are really interested in whether treatments can reduce attempted suicides, not whether they change patients’ answers in an interview or on a questionnaire.There is no doubt about the clinical and publi........

A whole slew of articles published by Ivan Gentile and colleagues based at the University of Naples (Italy) brought me to writing this post looking at some of the literature on viral exposures and autism. Viruses, in case you didn't know, are some of nature's survivors, infecting host cells and reproducing, onwards hopeful of finding more (un)willing cells/organisms to infect. Humankind have developed various biological defence mechanisms against the viral (and bacterial) onslaught that we all f........ Read more »
