How the brain processes humour helps us understand emotions felt by vegetative state patients
July 7, 2011 in Neuroscience(Medical Xpress) -- How the human brain processes jokes may help researchers determine if a person in a vegetative state can experience positive emotions a breakthrough that could help friends, relatives and doctors better understand a patients mental state of mind.
A team of researchers from Canada and the United Kingdom, led by Adrian Owen at The University of Western Ontarios internationally-renowned Centre for Brain and Mind, used functional magnetic resonance imaging (fMRI) technology to scan the brains of 12 healthy volunteers and compare their reactions to jokes with their reactions to standard, non-joking dialogue.
Owen says, Although our study looked at the brains response to jokes, our reasons for doing that were very serious. One of the main questions that families of severely brain injured patients ask us is can they still experience emotions? With the brain imaging technique we've developed here, we can answer that question in a simple and painless way.
The study and resulting paper, published in the prestigious Journal of Neuroscience, finds that the reward area of the brain lights up to a much greater degree when a joke is told compared to that of simply listening to regular conversation.
Recruited from the United Kingdom as the Canada Excellence Research Chair in Cognitive Neuroscience and Imaging this past year, Owen studies cognitive deficits problems in perceiving, thinking, reasoning and remembering in patients suffering from neurodegenerative diseases like Parkinsons, Huntingtons, Alzheimers and ALS (Lou Gehrigs disease).
