“…The majority of these studies indicated that there was a significant correlation between the facial and prosodic channels, as compared to correlations with the lexical channel [7,41,43,44,54]. In a similar vein, studies looking at emotional behavior showed that the right hemisphere hypothesis of emotional processing is supported by examining the emotional perception for facial and prosodic channels [27,68,91]. However, studies involving normal participants typically examined facial, prosodic and lexical communication channels in parallel [92,93].…”

“…This is consistent with findings reported by Heilman et al [48], in which RBD and LBD patients were equally impaired on the nonemotional prosody task compared with normal controls. However, other studies showed no significant impairments among RBD and LBD patients [27,49,80,81]. Some studies in which RBD patients were impaired at recognizing negative emotions from the prosodic task [25,35,41 ]provided support for the valence hypothesis.…”

“…These studies showed that individuals with RBD experienced greater difficulty in processing emotional faces than individuals with LBD and normal controls [6,7,25,26,30,35,39,41,43,44,48,54,63,64,65,66,67,68,69,70]. In contrast, most studies found no differences between RBD and LBD patients in the processing of emotional faces [27,31,45,60], and one study found that LBD patients were more impaired than RBD patients [71]. In the latter study, there were findings which provided support for the valence hypothesis.…”

“…Some of these differences include the length of time for which participants were exposed to stimuli, whether with [25,26,27,34,39] or without time restriction [32,43,54]. Kucharska-Pietura et al [26] imposed a time restriction for presentation of approximately 10 s, with an interval of 10 s between two consecutive photographs.…”

“…These study stimuli were mostly drawn from the New York Emotion Battery (NYEB) database [27,43,44], and most studies varied in the use of emotional prosody sentences. Past studies have asked participants to identify or discriminate the recorded emotional prosody category of semantically neutral sentences [26,28,29,45,46,47], low-pass filtered sentences [48,49,50], sentence pairs [7,33,51,52], congruent or incongruent sentences [53], pseudo-sentences [30,41,54] or hummed utterances [55].…”

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.

LSVT® LOUD (Lee Silverman Voice Treatment) is efficacious in the treatment of speech disorders in idiopathic Parkinson’s disease (IPD), particularly hypophonia. Functional imaging in patients with IPD has shown abnormalities in several speech regions and changes in these areas immediately following treatment. This study serves to extend the analysis by correlating changes of regional neural activity with the main behavioral change following treatment, namely, increased vocal intensity. Ten IPD participants with hypophonia were studied before and after LSVT LOUD. Cerebral blood flow during rest and reading conditions were measured by H215O-positron emission tomography. Z-score images were generated by contrasting reading with rest conditions for pre- and post-LSVT LOUD sessions. Neuronal activity during reading in the pre- versus post-LSVT LOUD contrast was correlated with corresponding change in vocal intensity to generate correlation images. Behaviorally, vocal intensity for speech tasks increased significantly after LSVT LOUD. The contrast and correlation analyses indicate a treatment-dependent shift to the right hemisphere with modification in the speech motor regions as well as in prefrontal and temporal areas. We interpret the modification of activity in these regions to be a top–down effect of LSVT LOUD. The absence of an effect of LSVT LOUD on the basal ganglion supports this argument. Our findings indicate that the therapeutic effect of LSVT LOUD in IPD hypophonia results from a shift in cortical activity to the right hemisphere. These findings demonstrate that the short-term changes in the speech motor and multimodal integration areas can occur in a top–down manner.
