9:59 PM | An earlier illusory death
For such an obscure corner of the medical literature, Cotard’s delusion is remarkably well known as the delusion that you’re dead. This was supposedly first described by Jules Cotard in 1880 but I seem to have found a description from 1576. It’s worth noting that although Cotard’s delusion has come to represent ‘the delusion that […]

9:00 PM | Death Rate From Heart Disease Declines 4 Percent Since 2000
Since the year 2000, mortality rates for heart disease declined by almost 4 percent even as higher blood pressure and obesity role, according to a new paper in JAMA. Matthew D. Ritchey, D.P.T., of the Centers for Disease Control and Prevention (CDC), Atlanta, and colleagues examined the contributions of heart disease subtypes, such as coronary HD (CHD) mortality, to overall heart disease (HD) mortality trends during 2000-2010. read more

8:27 PM | Beta-Blockers For Some Heart Failure Linked With Improved Survival
Up to 50 percent of patients with heart failure have normal or near-normal ejection fraction, termed heart failure with preserved ejection fraction (HFPEF). The risk of death in HFPEF may be as high as in heart failure with reduced ejection fraction (HFREF), but there is no proven therapy. Beta-blockers improve outcomes in HFREF and may be beneficial in HFPEF, but data are sparse and inconclusive, and beta-blockers are currently not indicated for treating HFPEF, according to background […]

5:30 PM | Hard Of Thinking: If You're Bad At Logic, Logically You Would Never Know
You might never know that you're hard of thinking. Robin Zebrowski/Flickr, CC BY-NCBy Stephan Lewandowsky, University of Bristol and Richard Pancost, University of BristolIt is an unfortunate paradox: if you’re bad at something, you probably also lack the skills to assess your own performance. And if you don’t know much about a topic, you’re unlikely to be aware of the scope of your own ignorance. read more

5:00 PM | Smooth Move: How GABAergic Interneurons Regulate Skilled Motor Behavior
In early 2014, the American free-solo rock climber Alex Honnold climbed 2,500 feet of limestone without ropes.  The demanding route called El Sendero Luminoso in El Potrero Chico, Mexico required 3 hours of intense concentration and precise movements. One wrong move and the young climber would have fallen thousands of feet with catastrophic consequences. In … Continue reading →

2:30 PM | 2014 - Global Warming Is Back On Track?
From 2000-2013 the global ocean surface temperature did not rise in spite of increasing greenhouse gas concentrations. This Global Warming Hiatus generated a lot of public and scientific interest and no small amount of skepticism about the accuracy of the numerical models created by climate scientists. But data is another matter entirely and as of April 2014 ocean warming has picked up speed again, according to a new analysis of ocean temperature datasets.  read more

2:00 PM | Gravitational Waves Could Unlock Secrets Of The Black Hole Universe
When two giant LIGO detectors are switched on in the US next year, they will help scientists pick up the faint ripples of black hole collisions millions of years ago, known as gravitational waves.  Black holes cannot be seen, but scientists hope the revamped detectors, which act like giant microphones, will find remnants of black hole collisions - and theoretical physicists hope experimentalists will give validation for their numerical model.read more

1:06 PM | #SfN14 Day 1: Tackling Difficult Mentor/Mentee Discussions
This post is part of my series on the 2014 Society for Neuroscience annual meeting. You can read other posts in this series here. I’m also live-tweeting some sessions @GainesOnBrains. Join the conversation at #SfN14.Greetings from D.C.! It’s nearly midnight on Saturday and my stomach is exploding from this chocolate torte I decided would be a good idea after a giant plate full of ravioli. It wasn’t a good idea, though. It was a GREAT idea.This afternoon, I attended life coach […]

9:54 AM | A New Search For The A Boson With CMS
I am quite happy to report today that the CMS experiment at the CERN Large Hadron Collider has just published a new search which fills a gap in studies of extended Higgs boson sectors. It is a search for the decay of the A boson into Zh pairs, where the Z in turn decays to an electron-positron or a muon-antimuon pair, and the h is assumed to be the 125 GeV Higgs and is sought for in its decay to b-quark pairs. If you are short of time, this is the bottomline: no A boson is found in Run 1 […]

3:36 AM | SfN blogging Day 1: How to have The Talk
Wowzers! Day one of SfN was non-stop. A day of delicately (haha) balancing science/ grad student poster activities with blogging activities. The Careers Beyond the Bench session this morning was packed. Big room packed with students and postdoctoral fellows wanting to know what else is out there, career-wise, and how they can get it. I'll be writing up short posts about each of the talks and

First day and great day. Please venture over to the Theme H posters on display til Sunday. In today’s finding climate, it’s great to see an emphasis on teaching and the history of our field. There are different teaching modalities for different demographics and that is the key to success. As for science, the clocks […]

1:02 AM | Know your brain: Substantia nigra
Where is the substantia nigra?The substantia nigra is a nucleus in the midbrain that is considered part of the basal ganglia. It looks like a darkened streak in unstained brain tissue; this is where it gets its name, which is Latin for "black substance." Although it is often referred to as one structure, the substantia nigra is actually made up of two anatomically and functionally distinct portions: the substantia nigra pars compacta and the substantia nigra pars reticulata. Neurons in the pars […]

12:56 AM | Collective noun for a group of electrophysiologists?
My husband and I have had an ongoing discussion for quite a while now about what the collective noun for a group of electrophysiologists should be. This discussion came up again a few nights ago, where he firmly believes that the collective noun should be a ‘superstition‘. I, on the other hand, think it should be a […]

10:18 PM | More on the enigma of blindness and psychosis
A long-standing enigma in psychiatry has been why no-one has been able to find someone who has both congenital blindness and a diagnosis of schizophrenia. The newest and most comprehensive archive study to date has just been published on exactly this issue although it raises more questions than it answers. Evelina Leivada and Cedric Boeckx […]

6:00 PM | Home Dialysis May Be Better Than In-Center Hemodialysis For Kidney Failure Patients
Home dialysis therapies may help prolong the lives of patients with kidney failure compared with hemodialysis treatments administered in medical centers, according to an upcoming study at ASN Kidney Week 2014 at the Pennsylvania Convention Center in Philadelphia, PA. Home dialysis therapies are more convenient and less expensive than in-center treatment, but it's unclear whether all home therapies - which include peritoneal dialysis and home hemodialysis - can prolong patients' survival.

5:13 PM | Air Pollution Linked To Higher Rates Of Chronic Kidney Disease
Air pollution may play a role in the development of kidney disease, according to a study upcoming at ASN Kidney Week 2014 November 11-16 at the Pennsylvania Convention Center in Philadelphia, Pennsylvania. There are wide variances in the prevalence of chronic kidney disease (CKD) across the United States, only part of which is explained by differences in individuals' risk factors. To see if air quality may also play a role, Jennifer Bragg-Gresham, PhD (University of Michigan) and her colleagues […]
