Welcome to the O’BRAIN Lab

The O’BRAIN Lab is a group of researchers inves­ti­gat­ing the inter­play between obe­si­ty and the brain.
Over­weight and obe­si­ty rates have risen steadi­ly in recent decades. Although many of us share sim­i­lar envi­ron­ments, only a few peo­ple become obese. How come? In our search for the cause, we are con­front­ed with a com­plex inter­play of many fac­tors: In addi­tion to the envi­ron­ment, behav­iour, brain func­tion, and genet­ic influ­ences deter­mine the deci­sions we make and thus ulti­mate­ly also our body weight.


We try to answer fun­da­men­tal ques­tions about obe­si­ty: How does obe­si­ty devel­op? Why is it so hard to resist tempt­ing food? Does our brain deter­mine what and how much we eat? How does our nutri­tion shape our brain? Do changes with­in the brain make it so dif­fi­cult for us to break bad eat­ing habits? Last but not least: How can we help to improve eat­ing habits?


Our team is cur­rent­ly based in two places: Leipzig (Ger­many) and Helsin­ki (Fin­land). We bring togeth­er researchers from var­i­ous dis­ci­plines such as neu­ro­bi­ol­o­gy, psy­chol­o­gy, cog­ni­tive sci­ence, math­e­mat­ics, and med­i­cine.

Es find­en momen­tan Tes­tun­gen statt. Es wurde ein umfan­gre­ich­er Kat­a­log von Hygien­e­maß­nah­men entwick­elt, um sowohl die Teil­nehmerIn­nen als auch das Per­son­al während der Exper­i­mente zu schützen. Wir suchen nach Per­so­n­en, die an unseren Stu­di­en teil­nehmen. Sie kön­nen unsere Forschung unter­stützen, indem Sie sich in unserem Proban­den­pool anmelden.

Delay to replication study

Dur­ing March we had the great news that the Dutch Research Coun­cil would fund an inter­na­tion­al repli­ca­tion study. Giv­en the cur­rent Covid-19 pan­dem­ic and the dis­rup­tion expe­ri­enced all over the world, a new start date has been set. We are hop­ing to start set­ting up from 1st Jan­u­ary 2021, with…
