From: Auditory streaming emerges from fast excitation and slow delayed inhibition
The auditory streaming paradigm. (A) Auditory stimuli consist of sequences of interleaved higher pitch A and lower pitch B pure tones with duration TD, pitch difference df and time difference between tone onsets TR (the repetition time; \(PR=1/TR\) is the repetition rate). (B) The stimulus may be perceived as either an integrated ABAB stream or as two separate streams A-A- and -B-B. (C) Sketch of the perceptual regions when varying PR and df (van Noorden diagram), redrawn after [9]. Bistability corresponds to the perception of temporal switches between integration and segregation. The curves in the \((PR,df)\) space separating integration from bistability and bistability from segregation are called fission and coherence boundaries
