1 Auditory perceptual organization
1.1. The problem According to the functionalist view of perception and cognition (Brunswik 1955), perceptual information processing serves to support the organism in reaching its fundamental goals: avoiding dangers and gaining access to resources. Both dangers and resources are provided by objects in our environment. Thus a large part of perceptual processing can be understood as answering the ...
متن کاملFunctional organization of ferret auditory cortex.
We characterized the functional organization of different fields within the auditory cortex of anaesthetized ferrets. As previously reported, the primary auditory cortex, A1, and the anterior auditory field, AAF, are located on the middle ectosylvian gyrus. These areas exhibited a similar tonotopic organization, with high frequencies represented at the dorsal tip of the gyrus and low frequencie...
متن کاملThe harmonic organization of auditory cortex
A fundamental structure of sounds encountered in the natural environment is the harmonicity. Harmonicity is an essential component of music found in all cultures. It is also a unique feature of vocal communication sounds such as human speech and animal vocalizations. Harmonics in sounds are produced by a variety of acoustic generators and reflectors in the natural environment, including vocal a...
متن کاملOrganization of sequential sounds in auditory memory.
A repeating five-tone pattern was presented at several stimulus rates (200, 400, 600, and 800 ms onset-to-onset) to determine at what temporal proximity the five-tone repeating unit would be represented in memory. The mismatch negativity component of event-related brain potentials was used to index how the sounds were organized in memory when participants had no task with the sounds. Only at th...
متن کاملAnatomical organization of the auditory cortex.
The identification of areas that contribute to auditory processing in the human cerebral cortex has been the subject of sporadic investigation for more than one century. Several anatomical schemas have been advanced, but a standard model has not been adopted by researchers in the field. Most often, the results of functional imaging or electrophysiological studies involving auditory cortex are r...
