Binaural characteristics of units in the owl's brainstem auditory pathway: precursors of restricted spatial receptive fields
A Moiseff and M Konishi
The barn owl uses binaural phase and intensity differences for sound
localization. These two cues also determine the receptive fields of
specialized neurons in the inferior colliculus. The main aim of this study
was to investigate where neuronal sensitivity to the binaural cues emerges
in the brainstem auditory nuclei, and how this sensitivity reaches the
neurons in the inferior colliculus. The owl's phase- sensitive neurons are
selective to microsecond phase differences of high frequency signals,
unlike mammalian phase-sensitive neurons which are restricted to low
frequency signals. In certain nuclei virtually all of the neurons are
sensitive to either phase differences or intensity differences, but not to
both. These nuclei form two distinctly separate pathways that converge at
the inferior colliculus where neurons selective to both phase and intensity
differences occur. In contrast to the mammalian auditory system, the owl's
phase- and intensity difference-sensitive pathways are not segregated into
low frequency and high frequency channels.
