Spectral plasticity in monkey primary auditory cortex limits performance generalization in a temporal discrimination task

Autor: Ralph E. Beitel, Maike Vollmer, Christoph E. Schreiner

Publikováno v: J Neurophysiol

Auditory experience and behavioral training can modify perceptual performance. However, the consequences of temporal perceptual learning for temporal and spectral neural processing remain unclear. Specifically, the attributes of neural plasticity tha

Passive stimulation and behavioral training differentially transform temporal processing in the inferior colliculus and primary auditory cortex

Autor: Ralph E. Beitel, Maike Vollmer, Christoph E. Schreiner, Patricia A. Leake

Publikováno v: Journal of Neurophysiology. 117:47-64

In profoundly deaf cats, behavioral training with intracochlear electric stimulation (ICES) can improve temporal processing in the primary auditory cortex (AI). To investigate whether similar effects are manifest in the auditory midbrain, ICES was in

Background noise exerts diverse effects on the cortical encoding of foreground sounds

Autor: Ralph E. Beitel, Christoph E. Schreiner, Brian J. Malone, Marc A. Heiser

Publikováno v: Journal of neurophysiology. 118(2)

In natural listening conditions, many sounds must be detected and identified in the context of competing sound sources, which function as background noise. Traditionally, noise is thought to degrade the cortical representation of sounds by suppressin

Amplitude modulation encoding is critical for human speech perception and complex sound processing in general. The modulation transfer function (MTF) is a staple of auditory psychophysics, and has been shown to predict speech intelligibility performa

Spatial Selectivity to Intracochlear Electrical Stimulation in the Inferior Colliculus is Degraded After Long-Term Deafness in Cats

Autor: Patricia A. Leake, Ralph E. Beitel, Maike Vollmer, Russell L. Snyder

Publikováno v: Journal of Neurophysiology. 98:2588-2603

In an animal model of electrical hearing in prelingually deaf adults, this study examined the effects of deafness duration on response thresholds and spatial selectivity (i.e., cochleotopic organization, spatial tuning and dynamic range) in the centr

Publikováno v: Journal of Neurophysiology. 84:166-183

Current cochlear prostheses use amplitude-modulated pulse trains to encode acoustic signals. In this study we examined the responses of inferior colliculus (IC) neurons to sinusoidal amplitude-modulated pulses and compared the maximum unmodulated pul
