ABSTRACT
This study tested the hypothesis that spiking activity in the primary auditory cortex of monkeys is related to auditory stream formation. Evidence for this hypothesis was previously obtained in animals that were passively exposed to stimuli and in which differences in the streaming percept were confounded with differences between the stimuli. In this study, monkeys performed an operant task on sequences that were composed of light flashes and tones. The tones alternated between a high and a low frequency and could be perceived either as one auditory stream or two auditory streams. The flashes promoted either a one-stream percept or a two-stream percept. Comparison of different types of sequences revealed that the neuronal responses to the alternating tones were more similar when the flashes promoted auditory stream integration, and were more dissimilar when the flashes promoted auditory stream segregation. Thus our findings show that the spiking activity in the monkey primary auditory cortex is related to auditory stream formation.
