On the verge of 2021, we published a new paper on behavioural control in obesity. Lieneke Janssen and colleagues found differences in the type of control used for decision-making between obese people on the one hand, and normal weight and overweight people on the other hand. The importance of examining...
Same same, but different
We have a new addition to our series on the relationship of smell perception and obesity. In our latest paper Maria Poessel and her co-authors find that people with higher BMI have lower olfactory bulb volume while olfactory function is seemingly still normal. The full story is available here.
New modelling paper
Our latest paper is concerned with dopamine release, diffusion and uptake. We provide a computational model (and corresponding software) which helps to refine our understanding of dopamine transmission, in particular the effects of pre-synaptic mechanisms. We hope it will be used further to investigate clinical questions associated with dopamine dysfunction...
Are we what we eat?
New Paper out!
How is loss of smell related to dietary choice? Check out our recent collaboration article titled The Aetiology of Olfactory Dysfunction and Its Relationship to Diet Quality to find out!
I like the smell of that
We are proud to present a new paper in our series on the relationship of smell (perception) and obesity. Maria Poessel and colleagues explore how metabolic health status, in particular insulin resistance, may play a key role in the altered perception of smell across a large sample of people with...
New Paper on automatic and controlled processing
Check out Annette’s new paper in Nutrients, investigating how automatic and controlled processing interact with regard to eating behaviour. The results outline how we might best achieve our long-term goals (of healthy eating habits).
Too much is not enough
We are proud to announce that Annette Horstmann has published an article (in German) in the magazine Spektrum der Wissenschaft, explaining how the brains of people with obesity are different to the brains of people with normal weight — and how that may explain why some people find it hard...
New paper in press: Mehl et al. on retraining automatic action tendencies in obesity
Check out our latest paper (in press) in Physiology & Behavior on retraining automatic action tendencies in obesity by Nora Mehl, Lara Mueller-Wieland, O’Brain alumni David Mathar, and Annette Horstmann. Read more here
Does it work this way? Annette’s model tried and tested
Annette’s proposed model of how dopaminergic tone varies (non-linearly) across normal weight, overweight and obese people has been tested empirically for the first time. Researchers in Spain conducted an fMRI experiment with which they confirm Annette’s idea with real data: the reward system in the brain appears to function differently but systematically across people...
