Auditory figure-ground analysis in rostral belt and parabelt of the macaque monkey.

Segregating the key features of the natural world within crowded visual or sound scenes is a critical aspect of everyday perception. The neurobiological bases for auditory figure-ground segregation are poorly understood. We demonstrate that macaques perceive an acoustic figure-ground stimulus with comparable performance to humans using a neural system that involves high-level auditory cortex, localised to the rostral belt and parabelt.
