What music do dogs prefer? Bach vs. Snoop Dogg
by Cobb & Hecht in Do You Believe In Dog?
Hey Julie,I hope you've had a fun week. I saw a new in-press publication with your name on it - "Smelling more or less: Investigating the olfactory experience of the domestic dog" - looks like a really great study, and so timely after my last post about dogs and olfactory enrichment! Looking forward to reading it (and all those other cool Learning and Motivation articles) over the weekend. So did you do your homework? Did you watch this clip from the Sydney Opera H........

Marijuana and Diabetes: Does Pot Make You Thin?
by Dirk Hanson in Addiction Inbox
Teasing out the insulin effect.
On the face of it, the study seems to come out of left field: A group of researchers claimed that marijuana smokers showed 16 per cent lower fasting insulin levels than non-smokers. The study, called “The Impact of Marijuana Use on Glucose, Insulin, and Insulin Resistance among US Adults,” is in press for The American Journal of Medicine. The authors are a diverse group of medical researchers from Harvard, Beth Israel Deaconess Medical Center, and t........ Read more »

Decision Theory Journal Club: Our brains are perfect machines
by neuroecology in Neuroecology
A few of us have started a Decision Theory journal club where we plan on reading papers from a variety of fields that examine how decisions are made. We have people from neuroscience, economics, and cognitive science participating (so far), including people participating through Google+ hangouts!, which will hopefully make lead to some productive discussions.

Dogs can haz brainscanz and EEG?
by CAPB in Companion Animal Psychology Blog
Canine cognition is a hot topic these days, using experiments and brain imaging as research tools. The trouble with brain imaging work is that it is invasive, to the extent that animals may have to be sedated or anaesthetized for the study. All that changed with the amazing work of Gregory Berns et al and the first-ever fMRI study on awake, unrestrained dogs last year. Now Miiamaaria Kujala et al in Finland have shown that it is also possible to do a non-invasive EEG with dogs.An EEG measur........ Read more »

Why don't men understand women?
by Isabel Torres in Science in the clouds
Men might have found themselves an excuse not to listen to women. New research suggests that men have twice more difficulty reading emotions in women than in men. This may not sound surprising, but evidence that men have trouble understanding women is, at best, scarce.Being able to guess someone else’s thoughts, feelings and intentions is an instinctive social skill that develops in early childhood. We might take it for granted, but people who struggle or are unable to read other people, like ........ Read more »

Epilepsy Service Organization in Countries with Limited Resources
by Vivek Misra in Beautiful Mind
tumblr: bellapaige88On average, 9.5/1000 population has epilepsy in Low and Middle Income Countries (LAMIC). A research which has resulted in the global campaign against epilepsy has shown, the gap between treatment need and the treatment provision worldwide is approximately 70% [1].

Epidemiology of Childhood Brain Disorders: ADHD and Autism

The U.S. Centers for Disease Control has published a comprehensive summary of the epidemiology of childhood brain disorders in the most recent Morbidity and Mortality Weekly Report.This report produced some sensationalized headlines that up to 20% of children suffer from a mental disorder. However, I was more interested in looking at the prevalence estimates for some of the individual disorders from the report.The report collates data collected from a variety of surveys and data sets inclu........

Homeostatic platsicity in a thorny situation
by TheCellularScale in The Cellular Scale
Synapses, the connections between neurons can strengthen and weaken depending on the specific activity at that synapse. This is called synaptic plasticity, and we've talked about it a lot on this blog (here, here, here and here).the strengthening and weakening of synaptic connections corresponds to the spine growing or shrinking (Matsuzaki 2007)However, there is another kind of plasticity that can occur at synapses. This is called homeostatic plasticity. And instead of the synapse strengthening ........ Read more »

The effectiveness of placebo treatment for pain is related to personality traits

Ladies: why Ritalin may not always be helpful. (Hint: sex, genes and dem hormones)

Little note: Since this post, I’ve been mulling over why Ritalin/Adderall don’t affect cognitive performance of healthy volunteers. Several reasons come to mind. I wasn’t reading the “right” literature (ie studies with positive results – any suggestions?). Stimulants may only influence brain activation patterns, but not performance. In this case, we can only detect differences […]... Read more »
