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 […]

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 […]

In a recent article in Science (also reported here), researchers report that faces coupled with negative stories (e.g. having thrown a chair at a classmate) led to an increase in visual attention to that person. Other kinds of stories, from neutral to positive, did not produce such an effect. This is taken as an indication […]

I just received an invitation from neurologist Jesper Rønager. Stuart Hameroff is coming to Copenhagen and gives a talk. Yesterday, I was invited to a meeting at with a small inner circle of neurologists and physicists, at the Niels Bohr Institute. Unfortunately, I was unable to attend, given the short notice of just one day […]

An already influential paper by Salimpoor et al. in Nature Neuroscience, suggests that we need to rethink how the reward system works, most notably the neural distinction between expectation and experience of rewards. By using PET scanning to probe the binding of dopamine in the (subcortical) brain, and using fMRI to learn more about the […]

What happens when we lose consciousness? Are there shared neural mechanisms for deep sleep, anaesthesia, vegetative state and coma? In 2003, I co-authored a paper (PDF) in Trends in Neuroscience (with Bernard Baars and Steven Laureys). Here, we suggested that there may be common neural mechanisms for loss of consciousness, in particular for vegetative state, […]

Here is a heads up for a recent study demonstrating – again – that the amygdala is not merely a “fear centre” in the brain. I have previously blogged about the amygdala, first not being a single structure, and that it is not only involved in fear. In 2007, a team of French researchers demonstrated […]

Just noticed this very attractive title by the Brafman brothers- The book, Sway – the irresistable pull of irrational behavior, “will challenge your every thought”, according to a NY Times review. And it gets similarly good reviews from other prominent people, like Michael Shermer, the author of the recent book The mind of the market, […]

Here is a heads up for the upcoming Sedbergh Festival of Ideas. Martin is going over to bring our view on the neuroethics of consciousness science research. Unfortunately, I’m unable to attend, but Martin will cover our ideas very nicely. The event Martin is talking at is “Event 4 — Varieties of consciousness“, together wih […]
