Orangutans make complex economic decisions about tool use  SCIENCE DAILY · 4 days
Flexible tool use is closely associated to higher mental processes such as the ability to plan actions. Now a group of cognitive biologists and comparative psychologists found out that the apes carefully... more
Uncovering the evolution of the brain  SCIENCE DAILY · 6 days
What makes us human, and where does this mysterious property of 'humanness' come from? Humans are genetically similar to chimpanzees and bonobos, yet there exist obvious behavioral and cognitive differences. Now, researchers have developed a strategy... more

Schema cells in the macaque hippocampus  Science Magazine · 2 weeks
Concept cells in the human hippocampus encode the meaning conveyed by stimuli over their perceptual aspects. Here we investigate whether analogous cells in the macaque can form conceptual schemas of spatial environments. Each day, monkeys were... more
