How your brain knows it’s summer

by Dr. Jekyll in Lunatic Laboratories

Researchers led by Toru Takumi at the RIKEN Brain Science Institute in Japan have discovered a key mechanism underlying how animals keep track of the seasons. The study shows how circadian clock machinery in the brain encodes seasonal changes in daylight duration through GABA activity along with changes in the amount of chloride located inside certain neurons....

The fear you experience playing video games is real, and you enjoy it

by Dr. Jekyll in Lunatic Laboratories

With the advent of video games, a frequently asked question has been whether we get as engrossed in them emotionally as we do when we see a scary movie. The answer is yes and many game players enjoy the fear caused by the zombies, disfigured humans and darkness they often encounter, the researchers found.... Read more »

Stand and Deliver: We Think Better on Our Feet — Literally

by Jeremiah Stanghini in Jeremiah Stanghini

Did you see the post from ScienceDaily a couple of months ago? As it turns out, we think better when we’re on our feet. Maybe more importantly though, given how much we tend to sit throughout the day, standing is a good way to … Continue reading →... Read more »

Fermented foods and social anxiety?

by Paul Whiteley in Questioning Answers

Stumbling across a headline that reads: 'Study Finds Decreased Social Anxiety Among Young Adults Who Eat Fermented Foods' was bound to pique my blogging interest. When I eventually tracked down the source paper behind the headline I became more and more intrigued as today I bring to your attention the study findings reported by Matthew Hilimire and colleagues [1].Implementing "a cross-sectional approach to determine whether consumption of fermented foods likely to contain probiotics interac........

We're more likely to cheat when we think it's our last chance to do so

by BPS Research Digest in BPS Research Digest

Imagine spending your school half-term week with a forgetful relative who always leaves money scattered around the house. Would you pinch any? If so, when, and why? A new paper suggests that we are most likely to “cheat at the end”, and uses a neat method to find out why.A number of theories predict we are likelier to cheat later than earlier. Perhaps we award ourselves moral credits for being good earlier, and later spend them like Catholic indulgences for guilt-free sin. Or maybe the strug........ Read more »

Blood & Fog: The Military's Germ Warfare Tests in San Francisco

by Rebecca Kreston in BODY HORRORS

The Nuremberg Code was drafted in 1947 following the appalling revelations of human experimentation committed in Nazi concentration camps. The overarching goal of the Code was to establish a set of rules for the ethical conduct of research using human subjects, guaranteeing that the rights and welfare of such participants would be protected. Two important principles guide and define this Code: the concept of voluntary, informed consent and that no experiment shall be conducted in which "there i........ Read more »

Pharma Make The Most of A Negative Result

by Neuroskeptic in Neuroskeptic_Discover

A misleading piece of statistical rhetoric has appeared in a paper about an experimental antidepressant treatment. The study is published in the Journal of Affective Disorders. JAD is a respectable mid-ranked psychiatry journal - yet on this occasion they seem to have dropped the ball badly.



The study examined whether the drug armodafinil (Nuvigil) improved mood in people with bipolar disorder who were in a depressive episode. In a double-blind trial, 462 patients were randomized to treat... Read more »

Rare neurons enable mental flexibility

by Dr. Jekyll in Lunatic Laboratories

Behavioral flexibility — the ability to change strategy when the rules change — is controlled by specific neurons in the brain, Researchers have confirmed. Cholinergic interneurons are rare — they make up just one to two percent of the neurons in the striatum, a key part of the brain involved with higher-level decision-making. Scientists have suspected they play a role in changing strategies, and researchers at OIST recently confirmed this with experiments.... Read more »

Cellular Senescence in Regeneration

by Max_Yun in the Node

Salamanders are remarkable organisms. Following the amputation or loss of complex structures such as parts of their eyes, hearts and brains, tails -including the spinal cord-, jaws and even full limbs, they are able to set up a regeneration programme which leads to the exact replacement of the missing structure, even as adults. As such, […]... Read more »

What personality features do heroes and psychopaths have in common?

by Scott McGreal in Eye on Psych

The search for a positive face of psychopathy prompted a study examining whether psychopaths and heroes share certain personality traits. Both psychopathy and heroism were correlated with a history of antisocial behavior, but the reasons for this remain unclear. Heroes might have more mature personalities than psychopaths, in spite of what features they may have in common. ... Read more »

Who Will Pay for All the New DBS Implants?

by The Neurocritic in The Neurocritic

Recently, Science and Nature had news features on big BRAIN funding for the development of deep brain stimulation technologies. The ultimate aim of this research is to treat and correct malfunctioning neural circuits in psychiatric and neurological disorders. Both pieces raised ethical issues, focused on device manufacturers and potential military applications, respectively.A different ethical concern, not mentioned in either article, is who will have access to these new devices, and who is goin........

Brain scan can predict who responds best to certain treatment for OCD

by Dr. Jekyll in Lunatic Laboratories

Tens of millions of Americans — an estimated 1 to 2 percent of the population — will suffer at some point in their lifetimes from obsessive-compulsive disorder, a disorder characterized by recurrent, intrusive, and disturbing thoughts (obsessions), and/or stereotyped recurrent behaviors (compulsions). Left untreated, OCD can be profoundly distressing to the patient and can adversely affect their ability to succeed in school, hold a job or function in society.... Read more »
