Happy new year — with a new paper!

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...

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...

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...

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...
