New paper on working memory in obesity

Does obe­si­ty relate to impair­ments in work­ing mem­o­ry gat­ing? That is what the study by Nadine Her­zog et al. focused on, and the results sug­gest it’s not about BMI per se – a BMI-genet­ic inter­ac­tion might play a role. Read more about the intrigu­ing insights here.

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…

We have a new addi­tion to our series on the rela­tion­ship of smell per­cep­tion and obe­si­ty.

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…
