“…The observed lateralization to the right hemisphere for lexical tone processing is not likely due to a presumably more difficult task for perceiving lexical tones than consonants because the auditory processing of lexical tones in native speakers would otherwise have been lateralized to the right hemisphere in the previous fMRI or PET studies (19)(20)(21) as well. Given the equal linguistic function of and the distinct acoustic features between a lexical tone and a consonant (Fig.…”

“…Arguing against this hypothesis are data from the fMRI or PET experiments that use lexical tones as the stimulus to demonstrate that additional areas of the left hemisphere will be activated in native tonal language speakers versus English speakers (19)(20)(21), suggesting the dependence of hemisphere lateralization based on linguistic functions and language experience rather than on acoustic features. Because fMRI or PET measures hemodynamic responses with a temporal resolution ranging from seconds to tens of seconds (22,23), the observation from these neuroimaging studies, which require subjects to execute a discrimination task, likely represents the temporally aggregated brain activities including those at an attentive stage of auditory processing.…”

In tonal languages such as Mandarin Chinese, a lexical tone carries semantic information and is preferentially processed in the left brain hemisphere of native speakers as revealed by the functional MRI or positron emission tomography studies, which likely measure the temporally aggregated neural events including those at an attentive stage of auditory processing. Here, we demonstrate that early auditory processing of a lexical tone at a preattentive stage is actually lateralized to the right hemisphere. We frequently presented to native Mandarin Chinese speakers a meaningful auditory word with a consonant-vowel structure and infrequently varied either its lexical tone or initial consonant using an odd-ball paradigm to create a contrast resulting in a change in word meaning. The lexical tone contrast evoked a stronger preattentive response, as revealed by whole-head electric recordings of the mismatch negativity, in the right hemisphere than in the left hemisphere, whereas the consonant contrast produced an opposite pattern. Given the distinct acoustic features between a lexical tone and a consonant, this opposite lateralization pattern suggests the dependence of hemisphere dominance mainly on acoustic cues before speech input is mapped into a semantic representation in the processing stream.hemispheric specialization ͉ mismatch negativity ͉ preattentive auditory processing

“…The activation of the left striatum is in agreement with lesion data, supporting its role in lexical-semantic processing (Wallesch and Papagno, 1988). In addition, a number of imaging studies have reported activations in the left putamen during language processing, but have not discussed its functional significance (e.g., Klein et al, 1994;Price et al,1997).…”

The current event-related fMRI study specifies the neuroanatomical correlates of semantic priming and differences in semantic relation types using an auditory primed lexical decision task (LDT). Word pairs consisted of different relation types, associations (key-chain), pure categorical relations (cow-dog), and unrelated words (table-window), as well as word-pseudoword (way-tinne) and pseudowordpseudoword (ahurn-dö va) pairs. The factor lexical status, i.e., the processing of words compared to pseudowords, was associated with activation in the middle temporal gyri and the left striatum. The factor relatedness, i.e., the contrast between unrelated and related target words, was associated with increased activation of the left inferior frontal gyrus, the deep frontal operculum bilaterally, and the middle frontal gyri. A direct contrast between the two semantic relation types indicated that the processing of purely categorical compared to associative information recruits the right precuneus, the isthmus gyrus cinguli, and the cuneus, suggesting more effortful processing of the former information type. The present data show that the factors lexical status, semantic relatedness, and type of semantic relation in a primed LDT modulate the hemodynamic response in cerebral areas that subserve auditory word recognition and subsequent lexical-semantic processing. © 2002 Elsevier Science (USA)

Spatio‐temporal distribution of brain activity associated with audio‐visually congruent and incongruent speech and the McGurk Effect

IntroductionSpatio‐temporal distributions of cortical activity to audio‐visual presentations of meaningless vowel‐consonant‐vowels and the effects of audio‐visual congruence/incongruence, with emphasis on the McGurk effect, were studied. The McGurk effect occurs when a clearly audible syllable with one consonant, is presented simultaneously with a visual presentation of a face articulating a syllable with a different consonant and the resulting percept is a syllable with a consonant other than the auditorily presented one.MethodsTwenty subjects listened to pairs of audio‐visually congruent or incongruent utterances and indicated whether pair members were the same or not. Source current densities of event‐related potentials to the first utterance in the pair were estimated and effects of stimulus–response combinations, brain area, hemisphere, and clarity of visual articulation were assessed.ResultsAuditory cortex, superior parietal cortex, and middle temporal cortex were the most consistently involved areas across experimental conditions. Early (<200 msec) processing of the consonant was overall prominent in the left hemisphere, except right hemisphere prominence in superior parietal cortex and secondary visual cortex. Clarity of visual articulation impacted activity in secondary visual cortex and Wernicke's area. McGurk perception was associated with decreased activity in primary and secondary auditory cortices and Wernicke's area before 100 msec, increased activity around 100 msec which decreased again around 180 msec. Activity in Broca's area was unaffected by McGurk perception and was only increased to congruent audio‐visual stimuli 30–70 msec following consonant onset.ConclusionsThe results suggest left hemisphere prominence in the effects of stimulus and response conditions on eight brain areas involved in dynamically distributed parallel processing of audio‐visual integration. Initially (30–70 msec) subcortical contributions to auditory cortex, superior parietal cortex, and middle temporal cortex occur. During 100–140 msec, peristriate visual influences and Wernicke's area join in the processing. Resolution of incongruent audio‐visual inputs is then attempted, and if successful, McGurk perception occurs and cortical activity in left hemisphere further increases between 170 and 260 msec.
