Ordering Procedure for Auditory Stimuli

Hemispheric specialization for processing auditory nonspeech stimuli.

The left hemisphere specialization for speech perception might arise from asymmetries at more basic levels of auditory processing. In particular, it has been suggested that differences in "temporal" and "spectral" processing exist between the hemispheres. Here we used functional magnetic resonance imaging to test this hypothesis further. Fourteen healthy volunteers listened to sequences of alte...

Emotional responses to auditory stimuli

In search of the best stimulus: an optimization procedure for finding efficient stimuli in the cat auditory cortex.

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...

Color and emotion caused by auditory stimuli

Recent studies have shown correlations between perceived colors and aspects of a musical piece such as tonality, tempo and musical articulation. Other studies have demonstrated that major and minor tonalities of music trigger people to perceived a different hue of colors. The purpose of this study is to investigate the correlation between musical aspects and the attribution of colors and emotio...

Neuromagnetic steady-state responses to auditory stimuli.

Steady-state magnetic responses to clicks presented at rates between 10 and 70 Hz have been recorded in healthy humans. The responses were highest in amplitude around 40 Hz. This amplitude enhancement is satisfactorily explained by summation of responses evoked by single clicks. The field maps suggest activation of the auditory cortex at all stimulus frequencies. Similar responses were obtained...
