“…of timbral sound attributes. Support for this hypothesis comes from studies by Chase [1967], Gordon [1974], Mazzuchini et al [1982], Denes et al [1984], and Samson and Zatorre [1994], suggesting that the timbre of environmental sounds, the human voice and of musical instruments is indeed more accurately processed by the right hemisphere.…”

The amplitude of the auditory evoked field (AEF) component N100m in response to tonal stimuli of varying spectral bandwidth and periodicity was compared with simulated peripheral activity patterns of the auditory nerve (AN). The AEF of ten subjects was recorded with a 37-channel axial gradiometer system (four independent measurement sessions per hemisphere). The simulated peripheral activity was characterized using measures derived from spike probabilities of the AN. Stimuli were pure tones, narrow-band harmonic complex tones (spectrum: 4–4.8 kHz), and broad-band harmonic complex tones (spectrum: 800 Hz–4.8 kHz) with periodicities of 100, 200, and 400 Hz. The intensity of all stimuli was set to 65 dB above the absolute thresholds. Both the simulated AN activity and measured cortical response amplitudes increased consistently with spectral bandwidth. This suggests that the enhanced sensitivity of the N100m amplitude to broad-band complex tones is to some extent a function of the auditory periphery.

“…Studies using an identification task found that RBD patients were significantly impaired relative to LBD patients and normal controls [44,48,75]. In studies using a discrimination task, RBD patients had impairment in the comprehension of emotional prosody task [58,76,77]. In a study by Ross and Monnot [78], different patterns of deficits were observed following left and right brain damage, suggesting that affective prosody is a dominant and lateralized function of the right hemisphere.…”

Objective: Patients suffering from stroke have a diminished ability to recognize emotions. This paper presents a review of neuropsychological studies that investigated the basic emotion processing deficits involved in individuals with interhemispheric brain (right, left) damage and normal controls, including processing mode (perception) and communication channels (facial, prosodic-intonational, lexical-verbal). Methods: An electronic search was conducted using specific keywords for studies investigating emotion recognition in brain damage patients. The PubMed database was searched until March 2012 as well as citations and reference lists. 92 potential articles were identified. Results: The findings showed that deficits in emotion perception were more frequently observed in individuals with right brain damage than those with left brain damage when processing facial, prosodic and lexical emotional stimuli. Conclusion: These findings suggest that the right hemisphere has a unique contribution in emotional processing and provide support for the right hemisphere emotion hypothesis. Significance: This robust deficit in emotion recognition has clinical significance. The extent of emotion recognition deficit in brain damage patients appears to be correlated with a variety of interpersonal difficulties such as complaints of frustration in social relations, feelings of social discomfort, desire to connect with others, feelings of social disconnection and use of controlling behaviors.

“…Indeed, when people are asked what distinguishes humans from computers, "emotion" leads the list. Recognition of emotion in speech is localized in the right hemisphere, in contrast to the processing of words, which is left-hemisphere dominant [2].…”
