Just like the brains of macaques, baboons, marmosets, galagos, owl monkeys and capuchins, the human brain devotes 8 percent of its neurons to the prefrontal cortex.
Its home range is often shared with other primate species including marmosets, squirrel monkeys, capuchins, owl monkeys, howler monkeys, and spider monkeys.
Between 12,00015,000 are imported each year, specifically rhesus macaque monkeys, cynomolgus (crab-eating) macaque monkeys, squirrel monkeys, owl monkeys, and baboons.
