Department of Psychology, Dalhousie University, Halifax, NS, Canada
J Am Acad Audiol 21:404-8. 2010..Auditory gap detection is a measure of temporal acuity. The paradigm comes in two forms, distinguished by whether the sounds bounding the silent period are the same (within channel [WC]) or different (between channel [BC])...

Hearing Research Laboratory, Department of Psychology, Dalhousie University, B3H 4J1, Halifax, NS, Canada

Hearing Research Laboratory, Department of Psychology, Dalhousie University, Halifax, NS, Canada B3H 4J1
Hear Res 167:192-205. 2002..Hypotheses about origins of the asymmetries, derived independently from psychophysics and from neurophysiology, have in common a response threshold mechanism which adaptively tracks the ongoing level of stimulation...

Synchronous auditory nerve activity in the carboplatin-chinchilla model of auditory neuropathyC D Cowper-Smith
Department of Psychology, Dalhousie University, 1355 Oxford Street, Halifax, Nova Scotia B3H 4J1, Canada
J Acoust Soc Am 128:EL56-62. 2010..These data suggest that (1), intact neural synchrony is available to support an ABR following carboplatin treatment and, (2), impaired spike timing intrinsic to neurons is required for the disruption of the ABR observed in human AN...
Factors shaping the response latencies of neurons in the cat's auditory cortexD P Phillips
Department of Psychology, Dalhousie University, Halifax, Canada
Behav Brain Res 93:33-41. 1998..These data show that in cortical neurons, it is not the peak stimulus intensity which determines first-spike latency, and second, that the response latencies are systematically not those expected on the basis of simple threshold model...
Sensitivity of unanesthetized chinchilla auditory system to noise burst onset, and the effects of carboplatinD P Phillips
Hearing ResearcDepartment of Psychology, Dalhousie University, Halifax, NS Canada B3H 4J1
Hear Res 155:133-42. 2001..The general patterns of sensitivity to stimulus level and rise time were not markedly affected by carboplatin, nor was the fashion in which response parameters (amplitude and latency) were ruled by rate of pressure change at sound onset...

Hearing Research Laboratory, Department of Psychology, Dalhousie University, Halifax, NS, Canada B3H 4J1

The relation between auditory temporal interval processing and sequential stream segregation examined with stimulus laterality differencesSusan E Boehnke
Dalhousie University, Halifax, Nova Scotia, Canada
Percept Psychophys 67:1088-101. 2005..These results suggest that perceptual segregation may be driven more effectively by differential activation of the two ears (peripheral channeling) than by differences in perceived laterality...
