The brain's reward centers in severely obese women continue to respond to food cues even after they've eaten and are no longer hungry, in contrast to their lean counterparts. The study compared attitudes and the brain activity of 15 severely obese women (those with a body mass index greater than 35) and 15 lean women (those with a BMI under 25).

A new Nature paper has earned a lot of media attention, unusually given that it's a fairly technical and 'basic' piece of neuroscience. In the paper, researchers Matthew F. Glasser and colleagues present a new parcellation (or map) of the human cerebral cortex, breaking the cortex down into 180 areas per hemisphere - many more than conventional maps.
But is this, as Nature dubbed it, "the ultimate brain map"?
To generate their map, Glasser et al. first downloaded 210 people's data from... Read more »

Granted, I am taking a slight departure from the material typically discussed on this blog by introducing the paper by Yan Zhang and colleagues  who reported the findings of a meta-analysis examining "the efficacy of different probiotic types, doses and treatment durations in IBS [irritable bowel syndrome] patients diagnosed by Rome III criteria via a meta-analysis of randomized controlled trials (RCTs)." The results however - "Probiotics are an effective pharmacological t........ Read more »
