Functional Organization of the Auditory Cortex

Representation Beyond Tonotopy in the Bat

Book cover Cortical Sensory Organization

Part of the book series: Cortical Sensory Organization ((CSO,volume 3))

Abstract

The properties of an acoustic signal produced by an animal can be studied by examining the output of a microphone displayed on the screen of an oscilloscope. Such an examination, however, gives us only limited information about the signal properties, so that the signal is usually analyzed with a spectrum analyzer. The spectrum analyzer has many filters tuned to different frequencies and it expresses the output of each as a function of time. Therefore, the properties of the acoustic signals are expressed by a pattern that appears in three coordinates: frequency, amplitude and time. To recognize individual acoustic patterns with an instrument, information-bearing elements (elements characterizing the signal) are first extracted and then their combinations are examined. The question next arises: how are acoustic signals analyzed and processed in the auditory system?
