“…Hemispheric specialization for perception, especially for perception of conspecific vocal signals, has been documented in humans (1)(2)(3)(4), macaques (5), and mice (6). Our interest in possible right-left asymmetries in brain pathways for avian song perception stems from the observation of laterality for the production of learned song (7,8), which is reminiscent of the hemispheric dominance for speech skills observed in humans (9,10).…”

Auditory input to the right or left forebrain of adult male zebra finches (Taeniopygiaguttata) was disrupted by lesloning the ipsilateral auditory relay nucleus of the tmus. These birds were then presented with two kinds of auditory discriminations: (T) between their own song and the song of a cage mate; (is) between two versions of an unfamiliar zebra finch song that differed only in the harmonic profile of one of the syllables. Right-side lesion birds did better than left-side lesion ones at discriminating between their own song and the song of a cage mate; left-side lesion birds did better on the harmonic profile task. We sugest that the two halves of the zebra finch brain process conspecific sounds differently, as seems to be the case for humans.

“…Yet clinical experience suggests that many right brain damaged stroke patients are depressed. Ross (1981) and Ross and Rush (1981) have argued that people with right brain damage may have a disturbance in processing affect both in understanding affect and expressing affect. Ross has used the term aprosodia to characterize the inability to process affect.…”

“…Expressive aprosodia can result from anterior cortical, posterior cortical, or subcortical lesions (Ross, 1981). Types of aprosodia, mirroring types of aphasia, have been posited (Ross, 1981). The emphasis of the present study is on expressive aprosodia whether or not it is accompanied by receptive deficits.…”

“…Traditionally, the left hemisphere has been assigned the major role in controlling linguistic prosody and the right hemisphere in controlling emotional prosody. A disruption of the comprehension or expression of emotional prosody has been called aprosodia (Monrad-Krohn, 1947;Ross, 1981;Myers, 1999). In the most severe cases of receptive aprosodia, a listener may be completely ignorant of a speaker's emotional intent, especially when the propositional verbal message differs from the prosodic emotional message (Bowers et al, 1987;Heilman et al, 1984).…”

This study investigated two mechanism-based treatments for expressive aprosodia, a disturbance in emotional prosody thought to be governed by the right hemisphere. The 3 participants all suffered right CVA's resulting in expressive aprosodia. Presence of expressive aprosodia was determined by performance on two batteries of emotional communication. A single subject ABAC design was employed in which two treatments, one imitative and one cognitive linguistic, were assigned in random order. All participants in this study were randomly assigned to begin with the cognitive linguistic treatment. Probes of treated and untreated emotions were completed during baseline and therapy phases. Probe items were judged by a reliable, trained rater blind to time of testing. Visual and statistical analyses were completed. These analyses confirmed that both treatments were active. For example, effect size calculations confirmed modest to substantial treatment effects for both treatments in all 3 patients. Replication to increase confidence about treatment effect and enhance understanding of the neuromechanisms underlying aprosodia is underway. (JINS, 2004, 10, 786-793.)
