Subject: [AUDITORY] How is sound stored in the brain? From: Dario Sanfilippo <sanfilippo.dario@xxxxxxxx> Date: Mon, 22 May 2017 07:01:57 -0700 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--001a113f5dfede8ad005501d5256 Content-Type: text/plain; charset="UTF-8" Hello, everybody. Would you be so kind to point out some research investigating how sound is stored in memory? I would assume that some kind of encoding is performed to optimise the amount of information that can be stored, but is there a generally accepted mechanism describing that process? For example, is it based on low-level descriptors such as loudness, brightness, roughness and noisiness? If a pitch is recognisable, will that have higher priority over the overall brightness of the sound event? Are the global/high-level behaviours of a sound event also stored in memory or are they processed "on the fly" based on the low-level descriptors each time a sound event is recalled? In this case, I guess that two sound events with a similar behavioural pattern but different local characteristics could recall each other. What is the resolution of this encoding? How many low-level characteristics can be stored at the same time? Thanks very much for your help.
