Congratulations to Huixin on successfully defending her doctoral thesis at CIBR!
Huixin joined the lab in 2021 as a Ph.D. student in the joint doctoral program between CIBR and Peking University. During her Ph.D. studies, she investigated how the hippocampus and orbitofrontal cortex (OFC) represent associative structure and interact to balance specificity and generalization across related experiences. Her work revealed that hippocampal CA1 representations emphasize context-specific information, whereas OFC representations generalize more strongly across sequences sharing a common structure. She further demonstrated that the two regions shape each other's representations: CA1 constrains representational alignment in the OFC, while the OFC supports representational alignment in CA1 during memory delays. These findings shed light on how interacting brain regions distinguish individual experiences while capturing their shared structure.
