Extensive observations have confirmed that elephants indeed remember injuries and hold grudges against their abusers. Elephant's Brain Temporal lobes have more foldings, so that they can store more information.
Elephants can recognize over 200 different individuals. This is essential, as females depend on one another for raising the young, more than in the case of other mammals. A mother can remember who is trustful and complex bounds are the bricks of elephants' society, while the memory is the cement. When two elephants approach one another, they emit a "contact appeal": if the other recognizes the appeal, it responds and approaches; if not, it starts to agitate and adopts a defensive position. This capacity of recognition lasts a very long time, even after one individual is dead.
An elephant's memory doesn't stow each detail of every stimulus ever encountered. Instead, the brain encodes what's necessary for survival, such as food location and family identification, in the same way that our short-term memory systems selectively discard or transfer data to our long-term storage [source: Trivedi]
The olfactory, or smell-related, region of an elephant's brain is extremely developed in relation to its other senses. Elephants can distinguish between the urine scents of up to 30 female relatives, even if they've been separated for years [source: Briggs]. This trait helps elephants stay together when traveling in large herds, with the urine serving as a bread crumb trail for the nose -- or trunk in this case.
While elephants' utilitarian memories help them retain essential survival information, they also allow these animals to recognize the past. Elephants' show signs of grief over dead relatives such as gently touching the corpses with their feet and caressing the bodies with their trunks [source: Shoshani et al]. In an experiment that involved showing different sets of objects to a family unit of elephants, the group responded most prominently to bones and tusks once belonging to a relative [source: University of Sussex]."
