Axon initial segment plasticity caused by auditory deprivation degrades time difference sensitivity in a model of neural responses to cochlear implants

Anna Jing, Shanshan Xi, Ivan Fransazov, Joshua H. Goldwyn

Synaptic and neural properties can change during periods of auditory deprivation. These changes may disrupt the computations that neurons perform. In the brainstem of chickens, auditory deprivation can lead to changes in the size and biophysics of the axon initial segment (AIS) …

Structure and dynamics that specialize neurons for high-frequency coincidence detection in the barn owl nucleus laminaris

Ben Drucker, Joshua H. Goldwyn

Abstract A principal cue for sound source localization is the difference in arrival times of sounds at an animal’s two ears (interaural time difference, ITD). Neurons that process ITDs are specialized to compare the timing of inputs with submillisecond precision. In the …

Glycinergic axonal inhibition subserves acute spatial sensitivity to sudden increases in sound intensity

Tom P. Franken, Brian J. Bondy, David B. Haimes, Joshua H. Goldwyn et autres

Locomotion generates adventitious sounds which enable detection and localization of predators and prey. Such sounds contain brisk changes or transients in amplitude. We investigated the hypothesis that ill-understood temporal specializations in binaural circuits subserve lateralization of such sound transients, based on different …

Dynamics of the Auditory Continuity Illusion

Qianyi Cao, Noah Parks, Joshua H. Goldwyn

Illusions give intriguing insights into perceptual and neural dynamics. In the auditory continuity illusion, two brief tones separated by a silent gap may be heard as one continuous tone if a noise burst with appropriate characteristics fills the gap. This illusion probes …

Author response: Glycinergic axonal inhibition subserves acute spatial sensitivity to sudden increases in sound intensity

Tom P. Franken, Brian J. Bondy, David B. Haimes, Joshua H. Goldwyn et autres

The location of impact sounds, common stimuli whose detection is crucial for survival, is encoded by a precise interaction between excitation and inhibition rather than coincidence detection of excitatory events.

Soma-axon coupling configurations that enhance neuronal coincidence detection

Joshua H. Goldwyn, Michiel W. H. Remme, John Rinzel

Coincidence detector neurons transmit timing information by responding preferentially to concurrent synaptic inputs. Principal cells of the medial superior olive (MSO) in the mammalian auditory brainstem are superb coincidence detectors. They encode sound source location with high temporal precision, distinguishing submillisecond timing …
