UCLA researchers have described a new form of irritable bowel syndrome that occurs after an acute bout of diverticulitis, a finding that may help lead to better management of symptoms and relief for patients.

The discovery of this new condition, called post-diverticulitis irritable bowel syndrome (PDV–IBS), validates the irritable bowel symptoms that many patients report long after suffering a bout of diverticulitis but that many physicians have waved off as being part of the original condition, said Dr. Brennan Spiegel, an associate professor of medicine at the David Geffen School of Medicine at UCLA and senior author of the research.

The interdisciplinary research team comprised researchers from five UK Universities (UCL, University of Cambridge, London Metropolitan University, De Montfort University Leicester and Brunel University), a doctor working in General Practice and a consultant from Public Health England. (more…)

A young woman’s educational performance may be hindered by her partner’s actions, such as destroying books or homework or causing injuries that prevent her from going to school. (more…)

Sleep helps the brain consolidate what we’ve learned, but scientists have struggled to determine what goes on in the brain to make that happen for different kinds of learned tasks. In a new study, researchers pinpoint the brainwave frequencies and brain region associated with sleep-enhanced learning of a sequential finger tapping task akin to typing, or playing piano.

PROVIDENCE, R.I. [Brown University] — You take your piano lesson, you go to sleep and when you wake up your fingers are better able to play that beautiful sequence of notes. How does sleep make that difference? A new study helps to explain what happens in your brain during those fateful, restful hours when motor learning takes hold. (more…)

Using neurofeedback techniques, Dr. Judson Brewer of Yale says he can teach people to “see” the subjective experience known to meditators as mindfulness. Brewer explains that too often we trip ourselves up when we get caught up in our own thinking. In the video and accompanying research papers, Brewer and colleagues describe how subjects can […]
