The paper records single-neuron activity in nonhuman primates to show frontopolar cortex encodes abstract representations of sounds and generates decision-making signals.

This study shows rhesus monkeys can evoke visual imagery from sounds in a crossmodal equivalence task, suggesting they can form conceptual representations.

This study investigates how humans perceive crossmodal correspondence between visual, acoustic, and tactile stimuli modulated by amplitude variations in natural sounds, finding that the number of amplitude prominences drives perception rather than temporal variations.

This study shows that SMA neurons transition from auditory to movement representations during sound-based decision tasks in monkeys.

This study shows that macaque supplementary motor area (SMA) activity correlates with perceptual invariance of sounds, suggesting motor predictions, not just sensory representations, underlie invariant recognition.

This study shows that rhesus monkeys can categorize new sounds based on their similarity to learned sounds, indicating their ability to perceive auditory invariance.
