The Bat Auditory Cortex

  • Chapter
Hearing by Bats

Part of the book series: Springer Handbook of Auditory Research ((SHAR,volume 5))

Abstract

Situated as it is at the top of the hierarchy of nuclei comprising the auditory pathway, the auditory cortex should provide a wealth of information about higher order analysis of acoustic signals. The auditory cortex in bats is arguably the most intensively studied and best understood of all mammals. One species in particular, the mustached bat Pteronotus parnelli, has provided a wealth of detailed information about neuronal specialization and cortical organization. Despite these advances, many auditory neuro-scientists tend to dismiss bat auditory neurobiology as “out of the main-stream” because they view bats as highly specialized mammals, with only one form of acoustic behavior, echolocation (but see Pollak, Winer, and O’Neill, Chapter 10). Some authors (e.g., Clarey, Barone, and Imig 1992) have questioned the applicability of the bat model of cortical organization because of the perception that bat cortex is highly specialized to analyze only the few stereotyped sounds used in echolocation. Bat researchers have inadvertently reinforced this bias by focusing their efforts only on echolocation, while ignoring the rich acoustic signal structures that bats use for communication. Only recently has there been any attention paid to the processing of the astonishingly rich variety of communication sounds used by colonial bats in social interactions (Kanwal, Ohlemiller and Suga 1993; Kanwal et al. 1994; Ohlemiller, Kanwal, and Suga 1993).
