here, we investigatedhow distinct training intensities, with strong or weakcontextual fear conditioning, affect activation of the dorsal hippocampus (dhpc) and the vhpc.we foundthatthe time course of memory consolidation differs in fear memories of different training intensities in both the dhpc and vhpc.our results also indicate that memory generalization happens alongside greater activation of the vhpc, and these processes occur faster with stronger fear memories.the vhpc is required for the expression of remote fear memory andmay controlcontextual fear generalization,a view corroborated by the fact that inactivation of the vhpc suppresses generalized fear expression, making memory more precise again. |
