Modeling and MEG evidence of early consonance processing in auditory cortex
Fig 2
Illustration of the decoding process.
The plots show the evolution of rate variables of the model during the processing of an iterated rippled noise with a fundamental period of T = 5 ms (parameters were as in Fig 1). (A–E) Evolution of the neural ensembles encoding characteristic periods between 0.5 ms and 20 ms. (A) Activity of periodicity detectors within the first stage of the model. (B, C) Activity of excitatory and inhibitory ensembles in the decoder network. (D, E) Activity of excitatory and inhibitory ensembles in the sustainer network. (F) Aggregated excitatory activity in the decoder (y-axis was inverted like in Fig 1A). Detailed dynamics of the process are illustrated in S1 Video.
