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........

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 »

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.

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 »

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 »

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% .

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.

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 »

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.

In this case, we can only detect differences […]... Read more »
