Those who work with gorillas have known for quite some time that the animals possess a brain that supports an intellectual level that far surpasses most other animals, including most other primates. In short, they’re really smart. Unfortunately, there is not much documented evidence to support such claims due to the few studies that have been done to measure it. This is because there are relatively few animals available in captivity that can be studied and because of the limited environment in which the animals live in the wild, which means, practically speaking, they don’t often run into situations that require much brainpower."... http://www.hangthebankers.com/two-young-gorillas-work-together-to-dismantle-the-poachers-trap-that-killed-their-friends-photos/ --- See also:

"Certain diseases such as gastrointestinal carcinoid tumors of the mid-gut, which sometimes release large amounts of 5-hydroxytryptamine, commonly known as 5-HT or serotonin into the blood, may produce a characteristic pattern of mostly right-sided cardiac fibrosis which can be identified at autopsy. This pathology has also been seen in certain West-African tribes who eat foods (Matoki—a green banana) containing excess amounts of serotonin".
