Monaural spectral contrast mechanism for neural sensitivity to sound direction in the medial geniculate body of the cat. J. Neurophysiol. 78: 2754-2771, 1997. Central auditory neurons vary in sound direction sensitivity. Insensitive cells discharge well to all sound source directions, whereas sensitive cells discharge well to certain directions and poorly to others. High-frequency neurons in th...

Background: There are extremely stressful stimuli in NICU environment. Although attempts have already saved neonates in this unit, this can disturb the adaptability of the infants in with environmental stimuli. Aim: To determine the effect of quiet time protocol implementation on physiological characteristics of preterm infants. Methods: In this cross-sectional clinical trial, 120 premature inf...

Functional magnetic resonance imaging (fMRI) of human auditory cortex has demonstrated a striking range of temporal waveshapes in responses to sound. Prolonged (30 s) low-rate (2/s) noise burst trains elicit "sustained" responses, whereas high-rate (35/s) trains elicit "phasic" responses with peaks just after train onset and offset. As a step toward understanding the significance of these respo...

BACKGROUND Although cochlear implant (CI) users frequently report deterioration of sound quality when listening to music, few methods exist to quantify these subjective claims. OBJECTIVE 1) To design a novel research method for quantifying sound quality perception in CI users during music listening; 2) To validate this method by assessing one attribute of music perception, bass frequency perc...

Units in the auditory cortex of cats respond to a large variety of stimuli: pure tones, AM- and FM-modulated signals, clicks, wideband noise, natural sounds, and more. However, no single family of sounds was found to be optimal (in the sense that oriented lines are optimal in the visual cortex). The search for optimal complex sounds is hard because of the high dimensionality of the space of int...

A combination of signals across modalities can facilitate sensory perception. The audiovisual facilitative effect strongly depends on the features of the stimulus. Here, we investigated how sound frequency, which is one of basic features of an auditory signal, modulates audiovisual integration. In this study, the task of the participant was to respond to a visual target stimulus by pressing a k...

Using computational models and stimuli that resemble natural acoustic signals, auditory scientists explore how we segregate competing streams of sound.
