A circuit for detection of interaural time differences in the brain stem of the barn owl
- C. Carr, M. Konishi
- Biology, PhysicsJournal of Neuroscience
- 1 October 1990
Findings indicate that the magnocellular afferents work as delay lines, and the laminaris neurons work as co- incidence detectors, which suggest that interaural time differences and their phase equivalents are mapped in each frequency band along the dorsoventral axis of the nucleus laminari.

Segregation of stimulus phase and intensity coding in the cochlear nucleus of the barn owl
- W. Sullivan, M. Konishi
- Biology, PhysicsJournal of Neuroscience
- 1 July 1984
The clear difference between the two nuclei in sensitivity to both phase and intensity and the reciprocity in response properties support the hypothesis that each nucleus is specialized to process one parameter (phase or intensity) and not the other.
Selectivity for interaural time difference in the owl's midbrain

A neural equivalent of these phenomena as they are observed in the space-specific neuron of the owl's inferior colliculus is reported, suggesting that nonlinear neural processes are involved.
A neural map of auditory space in the owl.

Auditory units that responded to sound only when it originated from a limited area of space were found in the lateral and anterior portions of the midbrain auditory nucleus of the owl (Tyto alba).…
Decrystallization of adult birdsong by perturbation of auditory feedback
- A. Leonardo, M. Konishi
- BiologyNature
- 3 June 1999
Evidence is presented that auditory feedback is actively used in adulthood to maintain the stability of song structure in adult zebra finches, and that adult birds that do not learn new songs nevertheless retain a significant amount of plasticity in the brain.
Neuronal growth, atrophy and death in a sexually dimorphic song nucleus in the zebra finch brain
- M. Konishi, E. Akutagawa
- BiologyNature
- 9 May 1985
The development of several forebrain nuclei involved in the control of song are studied and it is found that the dimorphism arises from neuronal atrophy and death in the female brain as well as from an increase in cell-body size and afferent terminals from other fore brain nuclei in the male.
Space and frequency are represented separately in auditory midbrain of the owl.
- E. Knudsen, M. Konishi
- PhysicsJournal of neurophysiology
- 1 July 1978
With this technique, two functionally distinct regions in MLD have been identified: a tonotopic region and a space-mapped region that are involved in different aspects of sound analysis.
Tolerance to Sound Intensity of Binaural Coincidence Detection in the Nucleus Laminaris of the Owl
- J. L. Peña, S. Viete, Y. Albeck, M. Konishi

It is hypothesized that inhibitory input whose strength increases with sound intensity protects nucleus laminaris neurons from losing their sensitivity to interaural time difference with intense sounds.
The role of GABAergic inhibition in processing of interaural time difference in the owl's auditory system
- I. Fujita, M. Konishi
- BiologyJournal of Neuroscience
- 1 March 1991
It is suggested that GABAergic inhibition sharpens ITD selectivity in the ICc and ICx, contributes to the elimination of phase ambiguity in theICx, and controls response magnitude and temporal characteristics in the VLVa, ICc, and ICX.
