A physiologically based model of interaural time difference discrimination.
Interaural time difference (ITD) is a cue to the location of sounds containing low frequencies and is represented in the inferior colliculus (IC) by cells that respond maximally at a particular best delay (BD). Previous studies have demonstrated that single ITD-sensitive cells contain sufficient information in their discharge patterns to account for ITD acuity on the midline (ITD = 0). If ITD d...
متن کاملFirst spike latency code for interaural phase difference discrimination in the guinea pig inferior colliculus.
First spike latency has been suggested as a source of the information required for fast discrimination tasks. However, the accuracy of such a mechanism has not been analyzed rigorously. Here, we investigate the utility of first spike latency for encoding information about the location of a sound source, based on the responses of inferior colliculus (IC) neurons in the guinea pig to interaural p...
متن کاملThe Caledonian face test: A new test of face discrimination
This study aimed to develop a clinical test of face perception which is applicable to a wide range of patients and can capture normal variability. The Caledonian face test utilises synthetic faces which combine simplicity with sufficient realism to permit individual identification. Face discrimination thresholds (i.e. minimum difference between faces required for accurate discrimination) were d...
متن کاملEffects of level and background noise on interaural time difference discrimination for transposed stimuli.
Just-noticeable interaural time differences were measured for low-frequency pure tones, high-frequency sinusoidally amplitude-modulated (SAM) tones, and high-frequency transposed stimuli, at multiple levels with or without a spectrally notched diotic noise to prevent spread of excitation. Performance with transposed stimuli and pure tones was similar in quiet; however, in noise, performance was...
متن کاملDifferences in short-term training for interaural phase difference discrimination between two different forced-choice paradigms.
Improvement in interaural phase difference (IPD) discrimination over 2 to 3 h was compared for two two-alternative forced-choice paradigms: A three-interval paradigm, in which the IPD was in interval two or three, and a paradigm with two intervals of four stimuli in which the IPD was in the second and fourth stimuli of one interval (AAAA vs ABAB). The difference in performance between the begin...
