Monkeys might not be known for their generosity, but when they do seem to act selflessly, a specific area in their brains keeps track of these kindnesses.

A human's self-awareness is controlled by a small region in the brain called the anterior insular cortex (insula). Within the insula lies a unique cell type - the von Economo neuron (VEN) - believed to be unique to humans, elephants, whales and great apes.

Researchers identify how social status in rhesus monkeys affects the way their genes turn on and off.

Oxytocin, the "love hormone" that builds mother-baby bonds and may help us feel more connected toward one another, can also make surly monkeys treat each other a little more kindly.

Taken together, these results demonstrate that disruption of the social bond causes reduction of activity throughout the “reward” and “motivation” circuitry that underlies social behavior, as well as in "social recognition" areas.
These results highlight that a non-human primate model is invaluable for further understanding the neural mechanisms underpinning selective pair-bonds.
This research was funded by the Good Nature Institute, NIH RR00169 and HD053555.

Being the top dog — or, in this case, the top gelada monkey — is even better if the alpha male is willing to concede at times to subordinates, according to a study by researchers from the University of Pennsylvania, the University of Michigan and Duke University. Alpha male geladas who allowed subordinate competitors into their group had a longer tenure as leader, resulting in an average of three more offspring each during their lifetimes.

Researchers have uncovered rare brain cells in monkeys, which can be tied to self-awareness and empathy in humans.
Max Planck scientists found that the anterior insular cortex is a small brain region that plays a crucial role in human self-awareness and in related neuropsychiatric disorders. An exclusive cell type – the Von Economo Neuron (VEN) – is located there. Via Edwin Rutsch

Researchers have produced the world's first chimeric monkeys. The bodies of these monkeys, which are normal and healthy, are composed of a mixture of cells representing as many as six distinct genomes.

Stephen Dubner describes the research of Keith Chen and his experiments with the monkey economy. Monkeys were taught to use money by economists to buy different commodities, hilarity ensues.
