“…Attention significantly modulated the magnitude of cortical activity in early visual and auditory sensory regions, and the dynamics of attention shifts were reflected in a crossover pattern of activity. These results corroborate and extend previous demonstrations of attentional modulation within vision and audition, respectively (Moran and Desimone, 1985;O'Craven et al, 1997;Tzourio et al, 1997;Jancke et al, 1999;Reynolds et al, 1999;Yantis et al, 2002), and confirm that our task effectively recruited selective attention and therefore could be used to examine the control of crossmodal attention shifts.…”

Selective attention contributes to perceptual efficiency by modulating cortical activity according to task demands. Visual attention is controlled by activity in posterior parietal and superior frontal cortices, but little is known about the neural basis of attentional control within and between other sensory modalities. We examined human brain activity during attention shifts between vision and audition. Attention shifts from vision to audition caused increased activity in auditory cortex and decreased activity in visual cortex and vice versa, reflecting the effects of attention on sensory representations. Posterior parietal and superior prefrontal cortices exhibited transient increases in activity that were time locked to the initiation of voluntary attention shifts between vision and audition. These findings reveal that the attentional control functions of posterior parietal and superior prefrontal cortices are not limited to the visual domain but also include the control of crossmodal shifts of attention.

“…The authors interpret this finding as a reflection of the specialization of the right auditory cortex for pitch perception because accurate pitch perception of one's own voice is required to adjust and maintain the intended pitch during singing. Tzourio et al [1997] found a significant rightward asymmetry between Heschl gyri and the posteriorly situated planum temporale for passive listening to tones compared to rest. Based on their findings they propose that right supratemporal regions, in particular the planum temporale, play an elementary role in pitch processing.…”

By means of fMRI measurements, the present study identifies brain regions in left and right peri-sylvian areas that subserve grammatical or prosodic processing. Normal volunteers heard 1) normal sentences; 2) so-called syntactic sentences comprising syntactic, but no lexical-semantic information; and 3) manipulated speech signals comprising only prosodic information, i.e., speech melody. For all conditions, significant blood oxygenation signals were recorded from the supratemporal plane bilaterally. Left hemisphere areas that surround Heschl gyrus responded more strongly during the two sentence conditions than to speech melody. This finding suggests that the anterior and posterior portions of the superior temporal region (STR) support lexical-semantic and syntactic aspects of sentence processing. In contrast, the right superior temporal region, in especially the planum temporale, responded more strongly to speech melody. Significant brain activation in the fronto-opercular cortices was observed when participants heard pseudo sentences and was strongest during the speech melody condition. In contrast, the fronto-opercular area is not prominently involved in listening to normal sentences. Thus, the functional activation in fronto-opercular regions increases as the grammatical information available in the sentence decreases. Generally, brain responses to speech melody were stronger in right than left hemisphere sites, suggesting a particular role of right cortical areas in the processing of slow prosodic modulations.

“…In examining the specific emotional intonations in both speech conditions it becomes apparent that prosodic speech indeed engages the left temporal (mSTR, pSTR) regions. Under the assumption that a determining parameter of prosody, namely pitch, is lateralized in the right hemisphere (e.g., Meyer et al, 2002;Tzourio et al, 1997;Zatorre & Belin, 2001;Zatorre & Samson, 1991), the reversed lateralization of the STR activation in the current experiment might be a reflection of the task at hand which forces the listener to search for meaning in degraded speech in order to make a judgment. Most importantly, this effect occurs independent of the valence of the emotional contour.…”

On the lateralization of emotional prosody: An event-related functional MR investigation

In order to investigate the lateralization of emotional speech we recorded the brain responses to three emotional intonations in two conditions, i.e., ''normal'' speech and ''prosodic'' speech (i.e., speech with no linguistic meaning, but retaining the Ôslow prosodic modulationsÕ of speech). Participants listened to semantically neutral sentences spoken with a positive, neutral, or negative intonation in both conditions and judged how positive, negative, or neutral the intonation was on a five-point scale. Core peri-sylvian language areas, as well as some frontal and subcortical areas were activated bilaterally in the normal speech condition. In contrast, a bilateral fronto-opercular region was active when participants listened to prosodic speech. Positive and negative intonations elicited a bilateral fronto-temporal and subcortical pattern in the normal speech condition, and more frontal activation in the prosodic speech condition. The current results call into question an exclusive right hemisphere lateralization of emotional prosody and expand patient data on the functional role of the basal ganglia during the perception of emotional prosody.
