Deepak Chopra has moved into the domain of the brain… and it should come as no surprise that what he claims is not only laughably erroneous, but also deeply misleading and ignoring the vast amounts of data for the view he so eagerly wants to discard. Why do I even bother? Because I care! I [...]

A recent post at Neuroskeptic discusses whether neuroimaging studies may provide a misleading picture of the brain. The issue is made relevant due to recent studies that demonstrate that for simple tasks, the brains were more or less globally active: Both studies found that pretty much the whole brain “lit up” when people are doing [...]

What happens in our brains as we get older? We probably all know what happens at the behavioral level. Most notable is the changes in memory, and the ability to couple information together. Remembering a name, or mixing names on people is a frequent effect. Forgetting what happened when and who did what are well-known [...]

A recent news item tells us about a report that the gustatory system in mammals has been shown to have a “gustatory map”. Just in the same way that we already know that our visual and sensory-motor systems show nice and almost 1:1 mapping between sense and it’s neural representation. It is groundbreaking work, as [...]

How are values computed in the brain? Rewards can be as many things: the expectation when having just ordered your favourite dish; the child’s joy at Christmas Eve; the enjoyment of good music or the wonderful taste of strawberries. But how does the brain process these many different kinds of rewards? Does it treat all types of [...]

How specific — or sparse — is the neural representation of a memory trace? Quian Quiroga and colleagues now have an article in Neuron (PDF), where they describe their well-known studies using single-cell recordings to well-known faces. As you most likely know, this has given rise to the debate about the “Jennifer Aniston neuron”. Their [...]

Nature is running a nice news article on the re-localization of Broca’s language area in the brain, and has as feature about it in their latest podcast. Pierre Paul Broca originally described patient cases in which the patient suffered speech production deficits following injury to the left frontal hemisphere. However, a revisit to Broca’s original [...]

Is binding the single most important concept in neuroscience? I think it is, even without making the concept too general or vague. On the contrary, binding seems to be a general concept to understand the workings of the brain. No more need for modules of perception, cognition, memory and action. Binding is the solution. More [...]

In an interesting paper in the latest version of Progress in Neurobiology, Yuri I. Arshavsky from UCSD writes about the epistemological dualism that exists in modern neuroscience. basically, Arshavsky claims that there is a covert dualism in the way that neuroscientists are treating mind-related topics, especially the study of “consciousness”. Indeed, as he claims: This [...]

Take any textbook on cognitive neuroscience. If you go through the book you wil see that there are chapters on perception (e.g. vision), memory, and language. Each chapter has its own vocabulary, theories and experimental evidence. Each chapter may even have been written by different authors (i.e. authorities). Once reading such a book you will [...]
