Monkeys also have the ability to observe

Some monkeys have the ability to observe details on a face to help them identify acquaintances, even on a corrected photo.

Scientists know that the rhesus macaque monkey is in the cortex of the temporal cortex of nerve cells that respond to a familiar face. However, they do not understand how their brains handle these images.

The group of German researchers at the Max-Planck Institute confirmed they had found an explanation. To achieve this, David Leopold and colleagues studied two male rhesus macaque monkeys that have been trained to identify many human faces on computers. They showed them a series of familiar photos, but some of them were fixed.

The results showed that the neurons in the temporal cortex of these monkeys reacted strongly when they detected small changes compared to their memories. Like humans, monkeys can use this ability to detect on a face signs of emotions.

Recent tests carried out in monkeys in Japan have revealed that even the most simplified images (round heads with ears, eyes) are enough to cause a reaction.
