Abstract
Depth-electrode recordings from the auditory cortex of humans undergoing presurgical evaluation for epilepsy allow the recording of ensemble responses to pitch in the form of local field potentials. These recordings allow another test of the hypothesis that there is a specialized neural ensemble for pitch within auditory cortex. Moreover, the technique allows recordings from multiple sites with millisecond temporal resolution to allow modeling of the effective connectivity between these sites. Here we argue that this takes the form of a hierarchical network of pitch-sensitive regions. Activity can be understood as reflecting predictive coding, in which perceptual predictions and error messages are continuously exchanged between a higher pitch center and lower-level auditory cortex.
