““It’s a bad combination for the amygdala to be oversensitized while the hippocampus is compromised: painful experiences can then be recorded in implicit memory—with all the distortions and turbo-charging of an amygdala on overdrive—without an accurate explicit memory of them. This might feel like: Something happened, I’m not sure what, but I’m really upset. This may help explain why victims of trauma can feel dissociated from the awful things they experienced, yet be very reactive to any trigger that reminds them unconsciously of what once occurred. In less extreme situations, the one-two punch of a revved-up amygdala and a weakened hippocampus can lead to feeling a little upset a lot of the time without exactly knowing why.””
