Food can trigger overconsumption similar to alcohol and drugs, but it is not the whole story

A large analysis of personality studies has found that people with obesity behave somewhat like people with addictions to alcohol or drugs. But obesity is also a complex condition that cannot be fully explained by the addiction model.

Scientists demonstrate flaws in protein detection tools, and outline a solution

A new study points to the need for better antibody validation, and outlines a process that other labs can use to make sure the antibodies they work with function properly.

Antibodies are used in laboratories and clinics to study proteins, which are the biomolecules that translate information from an organism’s genes into the structure, function, and regulation of its tissues and organs. Genetic mutations can cause protein imbalances or malfunctions, leading to human disease.

Cortical stimulation-induced seizures have the potential to guide epilepsy surgery, significantly reducing hospital stays

Surgery is the only way to stop seizures in 30 per cent of patients with focal drug-resistant epilepsy. A new study finds that inducing seizures before surgery may be a convenient and cost-effective way to determine the brain region where seizures are coming from.

Have you ever spent half an hour trying to take the best photo of your pets but they won't stay still in the perfect angle? This is also true for small animal imaging research using positron emission tomography (PET). Because of this, the use of anesthesia is a widespread practice in animal imaging. It’s one of the biggest limitations to imaging studies because anesthesia alters the animal’s normal physiological state, blurring the answers to the questions that many researchers have been asking.

Scientists prove difference between expected/actual outcomes cause reward response

If you love it when a musician strikes that unexpected but perfect chord, you are not alone. New research shows the musically unexpected activates the reward centre of our brains, and makes us learn about the music as we listen.

Ghrelin promotes conditioning to food-related odours

The holiday season is a hard one for anyone watching their weight. The sights and smells of food are hard to resist. One factor in this hunger response is a hormone found in the stomach that makes us more vulnerable to tasty food smells, encouraging overeating and obesity. New research on the hormone ghrelin was published on Dec. 4, 2018, led by Dr. Alain Dagher’s lab at the Montreal Neurological Institute and Hospital of McGill University.
