After graduating my MSc in Neuroscience from Utrecht University I started my PhD here at the Memory Dynamics lab in collaboration with Prof Benno Roozendaal at the Donders Institute. I am very grateful that I was given the opportunity to work in dr. Kay Tye’s lab at MIT in my second year for 6 months to learn optogenetics and in vivo calcium imaging. As a result, we are now successfully utilizing these techniques in our lab. I am mainly interested in how memories are gradually constructed in medial prefrontal cortex. To investigate this, we are employing in vivo calcium imaging to study cell assemblies in medial prefrontal cortex as mice learn the object space task.
