BSc and MSc Students


Sofia Castro e Almeida

I am doing a one year project in the Willuhn group with Aishwarya Parthasarathy and Bastijn van den Boom. The aim of our project is to gain better understanding corticostriatal projections during action selection and execution through Go/No-go reward and punishment tasks in rats. To achieve this, we are using calcium fluorescent imaging to record rat neuronal activity in the medial prefrontal cortex and dorsal striatum.  I am from Portugal and I really like to spend time travelling, meeting new people and sailing.

I am an intern in the Willuhn group, where I am involved in two projects. In one project, I support Wouter van Elzelingen with the validation of a new behavioral test for habit formation. In the second project, we measure dopamine release in the striatum during aversive and appetitive stimuli with fast scan cyclic voltammetry. In this project I support Jessica Goedhoop.


Peter August Rasmussen

I am doing an internship under Bastijn van den Boom as part of my MSc thesis project.

My project is concerned with treating compulsivity with deep brain stimulation (DBS). We use a mouse model for compulsive behavior, which we image during free behavior using endoscopic calcium imaging. We are interested in optimizing DBS parameters for treatment efficacy and energy usage, as well as characterizing the neuronal response to DBS.

During my stay I have also worked with automatizing behavioral annotation by employing DeepLabCut and machine learning techniques.
