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 based in Leipzig and brings togeth­er researchers from var­i­ous dis­ci­plines such as neu­ro­bi­ol­o­gy, psy­chol­o­gy, cog­ni­tive sci­ence, math­e­mat­ics, and med­i­cine.

Last call for study participation (in German only)

Until the end of Novem­ber we are look­ing for the last male vol­un­teers (Ger­man only) to com­plete our study on the influ­ence of fat and sug­ar on the brain. Help sci­ence and get in touch with us via 0341–9940 2629 or dopamin-diet@cbs.mpg.de. We are look­ing for­ward to wel­com­ing you!   

Welcome Minka

It’s our great plea­sure to wel­come our first Helsin­ki stu­dent to the team. Min­ka, who is a Mas­ter stu­dent of psy­chol­o­gy, will be inves­ti­gat­ing whether olfac­to­ry stim­u­la­tion influ­ences auto­mat­ic action ten­den­cies in obe­si­ty. We are very proud to have a first col­lab­o­ra­tion between our 2 labs as the data was…
