Psycasm - TODO LATER. A story of procrastination and forgiveness.

by Rift in Psycasm


[Wherein our hero puts it off... but later returns and wonder how, and why, it could've been done better]So I'm at the pointy end of the semester. My exams have all been turned in and now I'm left to deal with the rising spectre of exams. It's wierd - you can work as hard as you like all semester and earn up to 50% of your overall grade, but the final exam is the kicke; (read more)

Waves of Mu, Mirror Neurons, and Funny Hats

by Princess Ojiaku in Science with Moxie

Mirror neurons have been a hot topic in neuroscience for the past decade or so, and more evidence has been amassed in recent years of their exciting properties. Mirror neurons are so interesting precisely because they fire or are activated both when an individual performs an action AND when that same individual merely observes another performing an action. This intriguing property has lead researchers to speculate that these neurons could be responsible for empathy and the learning of actions an........ Read more »

Shock and Cure - With Magnets

by Neuroskeptic in Neuroskeptic

Electroconvulsive therapy (ECT) is the oldest treatment in psychiatry that's still in use today. ECT uses a brief electrical current to induce a generalized seizure. No-one knows why, but in many cases this rapidly alleviates depression - amongst other things.The problem with ECT is that it may cause memory loss. It's hotly debated how serious of a problem this is, and most psychiatrists agree that the risk is justified if the alternative is untreatable illness, but it's fair to say that whether........

Gamblers Rewarded by Near Misses

by Darcy Cowan in Skepticon

Earlier this year a study published in the Journal of Neuroscience looked at the brains of compulsive gamblers and concluded that when the the gamblers suffered “near-miss” losses their brains reacted as if they had won. Another study published slightly later in the Journal of the Experimental Analysis of Behaviour also looked at the brains [...]... Read more »

Does Ketamine Cause Bladder Damage?

by Dirk Hanson in Addiction Inbox


Special K and Cystitis.

Normally, Addiction Inbox steers clear of alarmist stories about drug use. A lifetime of wildly overstated verbiage about “false drugs,” as the Firesign Theatre comedy group once delightfully phrased it, has left me wary of drug scare stories. Even obvious cases, like Fetal Alcohol Spectrum Disorder and crack babies, are more nuanced problems than most coverage has alleged.

For years now, rumors about bladder problems in recreational users of ketamine have periodi........ Read more »

Why Is Anorexia Nervosa Neglected for Drug Development?

by William Yates, M.D. in Brain Posts

Atypical Antipsychotic OlanzapineEating disorders have been a neglected area for high-quality psychopharmacologic research.  There are probably several reasons for this.  The classic eating disorder anorexia nervosa is relatively rare and identifying 500 to 1000 subjects for a clinical trial would likely be a significant (but not impossible) research challenge.   There are currently no FDA approved drugs indicated for the treatment of anorexia nervosa.One drug in the U.S. has........

Bashford Dean: bridging medieval armor and Devonian fish

by Lucas in thoughtomics






The figure below comes from Helmets and Body Armor in Modern Warfare, a book written by the medieval armour expert Bashford Dean (1867 – 1930). The similarities between the evolution of these European war helmets and ‘proper’ biological evolution are striking. At the base we can see the ancestor of this clade of helmets: the [...]...

Einstein's brain

by Daniel in Ego sum Daniel

Einstein's brain was photographed only hours after his death. Ref: Falk (see reference below) Einstein's brain pops up quite often in popular science lore about the relation between brain size and intelligence. The most common myth (based solely on my own experience) is that Einstein's brain was smaller than average ergo brain size has nothing to do with intelligence. In actual fact, the size of Einstein's brain (as measured when retrieved shortly after his death at 76) was completely unremarkab........ Read more »

Putting the genetics in optogenetics

by miko in Reaction Norm

Someone will get a Nobel prize for the development of the techniques that now go by the name optogenetics, and my prediction is that it will be soon—maybe even a faster turnaround time than RNAi, the Nobel for which was given in 2006 for a discovery published in 1998.  Here’s the Wikipedia definition: Optogenetics is [...]...

Open source software pays its way

by David Bradley in Sciencetext

Open source computing was once described as an “anarchistic, caffeinated, hirsute world of hackers”.

Ancient Archosaur Arthritis

by Brian Switek in Dinosaur Tracking

When we envision prehistoric life, we often picture long-extinct animals in the most healthy state possible. Each restored individual is the acme of its particular species—be it Allosaurus or a woolly mammoth—but we know that things in the natural world are never so clean and neat. Not only do individual animals of any species vary [...]... Read more »

Evidence for paternal programming from obesity?

With The Touch of One’s Own Hand

Hearing shapes

Perception of shapes is possible by touch and by sight. Kim and Zatorre have been using a coding of shape information into sound information to examine the nature of shape perception. They use boards with 2D drawings on them have textured surfaces giving visual and tactile targets. These are coded to give matching ’soundscapes’ where [...]... Read more »

To clot or not: the trigger for coagulation

J. 98 1751-1761), which also aims to use modeling to probe the mechanisms of clot formation.  There’s [...]... Read more »
