The net result is that the presence of a relatively small population of hEGCs, in numbers and with characteristics similar to those observed in the BAX-/- mice - and in rodents that have had SE or febrile seizures - can cause a disproportionately large disruption of memory storage and retrieval in the CA3 network. Here, BAX is linked to Febrile seizure (within the age range of 3 months to 6 years).
