Last week two of our manuscripts were accepted by the peer-reviewed journal Learning & Memory. They will appear back to back in the same issue. Those are my first back to back publications and I’m happy it turned out that way.The articles are about how fruit flies (Drosophila melanogaster) learn what is important in their environment and how they use this information to form flexible memories. For instance, the flies learn that certain visual patterns in their environment can predict dangerous heat. If this predictive learning takes place in a colored background (say, green), the flies are flexible enough to treat the "dangerous" patterns still as dangerous in a new background color (one they can distinguish from green, say, blue-green). If however, these same colors indicate that different sets of patterns are dangerous in different colors, the flies can learn such "if-then" relationships as well. For example, the animals can learn: "if the background is ...

I came back from the 5th FENS meeting in Vienna on Thursday. I had arrived there with the most negative expectations of boring neuromedicine: posters and presentations full of Parkinson’s Alzheimer’s and other diseases. Which is exactly what happened! Brain diseases have, compared to experiments on healthy brains, relatively little to offer in terms of how brains work. Therefore, I’m always utterly bored and now, after so many years, seriously annoyed by large masses of narci...

There actually was one piece of exciting news besides the soccer World-Cup this week! Hackjin Kim and colleagues (in the lab of John O’Doherty) have published in PLoS Biology that the relief after the offset of pain activates the same brain areas as reward does (New Scientist, ScienceDaily). They found that neural activity increased in a region previously implicated in encoding stimulus reward value, the medial orbitofrontal cortex, not only following receipt of reward, b...
