Kyle Puhger, Ana P Crestani, Cassiano R A F Diniz, Brian J Wiltge. The hippocampus contributes to retroactive stimulus associations during trace fear conditioning. iScience. vol 27. issue 3. 2024-02-20.

PMID:38272026. by synthesizing studies across the rodent and human literature, we suggest that as memory representations initially form in hippocampus, parallel traces emerge in frontal cortex that cue memory recall, and as they mature, with sustained support initially from limbic then diencephalic then cortical circuits, they become progressively independent of hippocampus and dependent on a mature cortical representation. 2024-01-25 2024-01-28 human
