12.12.2020 Congratulations Luca!
Luca’s first paper of her PhD thesis has been accepted for publication in Nature Communications! Luca shows that the cortical balance between excitation and inhibition (E/I balance) plays region-specific roles in different kinds of decision making. E/I balance in one region (dorsal anterior cingulate cortex) influences how we balance the value of moving away from a depleting resource against the cost of leaving. In contrast, E/I balance in another region (ventromedial prefrontal cortex) is related to simple reward-maximizing choices.

04.07.2020: Congrats Lennart!
Lennart just published the first paper of his PhD thesis! His work shows that decisions are not only guided by memories, but decisions themselves modify hippocampal stimulus-outcome associations - and thereby bias future decisions.
