Changes in the auditory scene include the formation of new objects from the acoustic background, change in the properties of existing objects, in addition to the appearance or disappearance of objects from the scene. This chapter summarizes results of imaging the processing of these attributes of auditory stimuli that takes place in parallel during a time period of about 100 msec (80–170 msec) after onset of a sound.
Electrophysiological functional imaging of auditory processing of sound onset, offset, it's detection as deviant and its formation from a cluster of acoustic features allowed reasonable spatial resolution coupled with unparalleled temporal resolution. Such imaging allowed following the time course of processing a variety of sounds attributes. The time courses that are thus revealed are sensitive to the nature of the stimulus and different aspects of the stimulus were found to be analyzed in parallel in different brain areas. Different modes of processing manifest in different time courses of brain activity as revealed by electrophysiological functional imaging of dyslexics vs. normal readers.
These results indicate that the brain is a parallel processor that simultaneously handles many aspects of the processed material and adapts this processing with experience.
