Please share: I am recruiting a PhD student to join my lab in Oslo!

For this project, we will investigate the role of striatal interneurons during action selection, using a combination of behavior, in vivo voltage imaging, and slice ephys.

A prefrontal cortex map based on single-neuron activity - Nature Neuroscience The authors mapped spontaneous and choice activity across mouse prefrontal cortex. The activity maps aligned with intrinsic connectivity rather than anatomical subregions, suggesting that connectivity, not cytoarchitecture, organizes prefrontal function.
