Multi-pitch perception is investigated in a listening test using 30 recordings of musical sounds with two tones played simultaneously, except for gong inharmonic overtone spectra, judging roughness and separateness as the ability to tell each recording apart.

How is information processed in the cerebral cortex? In most cases, recorded brain activity averaged over many (stimulus) repetitions, which erases fine-structure of neural signal. However, obviously a single-trial processor. Thus, we here demonstrate that an unsupervised machine learning approach can be used to extract meaningful from electro-physiological recordings on basis. We use auto-encoder network reduce dimensions single local field potential (LFP) events create interpretable clusters different patterns. Strikingly, certain LFP shapes correspond latency differences recording channels. Hence, determine direction flux cortex. Furthermore, after clustering, decoded cluster centroids reverse-engineer underlying prototypical event shapes. To evaluate our approach, applied it both extra-cellular rodents, and intra-cranial EEG humans. Finally, find channel during spontaneous sample realm possible stimulus evoked A finding so far has only been demonstrated for multi-channel population coding.
