“…Area Spt also responds during the temporary maintenance of a list of words in short-term memory independently of whether the items to be maintained were presented auditorily or visually (Buchsbaum, Olsen, Koch, Kohn, Kippenhan, & Berman, 2005b). This latter finding parallels claims that visual-motor integration areas have working memory-related properties (Murata et 1 Spt is functionally defined within an anatomically constrained region of interest.…”

“…al., 1996), as well as the observation that sensory input from multiple modalities can drive neurons in PPC sensory-motor fields (Cohen, Batista, & Andersen, 2002;Mullette-Gillman, Cohen, & Groh, 2005). In sum, the response properties of area Spt -particularly that it shows both sensory and motor responses -are consistent with the hypothesis that it is a sensory-motor integration region similar to those found in the primate intraparietal sulcus (Buchsbaum et al, 2005b).…”

“…A region in the posterior Sylvian fissure at the parietal-temporal boundary (area Spt), known to have auditory-motor response properties (Buchsbaum et al, 2001(Buchsbaum et al, , 2005bHickok et al, 2003;Hickok & Poeppel, 2004;Okada & Hickok, 2006), was found to be substantially more active during covert humming of novel melodies than during covert playing on a keyboard of those same melodies. This finding is in support of the hypothesis that area Spt is a sensorymotor integration area for the vocal tract motor system.…”

“…This finding is in support of the hypothesis that area Spt is a sensorymotor integration area for the vocal tract motor system. There is substantial evidence from previous studies suggesting that area Spt, a sub-region of PT, is involved in sensory and motor outputs of the vocal tract (Buchsbaum et al, 2001;Hickok et al, 2003;Buchsbaum et al, 2005b). Until now, this specialization of area Spt has not been contrasted with a different motor effector in a within-subjects design.…”

A parietal–temporal sensory–motor integration area for the human vocal tract: Evidence from an fMRI study of skilled musicians

Several sensory-motor integration regions have been identified in parietal cortex, which appear to be organized around motor-effectors (e.g., eyes, hands). We investigated whether a sensory-motor integration area might exist for the human vocal tract. Speech requires extensive sensory-motor integration, as does other abilities such as vocal musical skills. Recent work found a posterior region, area Spt, has both sensory (auditory) and motor response properties (for both speech and tonal stimuli). Brain activity of skilled pianists was measured with fMRI while they listened to a novel melody and either covertly hummed the melody (vocal tract effectors) or covert played the melody on a piano (manual effectors). Activity in area Spt was significantly higher for the covert hum versus covert play condition. A region in the anterior IPS (aIPS) showed the reverse pattern, suggesting its involvement in sensory-manual transformations. This finding suggests that area Spt is a sensorymotor integration area for vocal tract gestures for, at least, speech and music.

“…Increased bilateral activation of posterior temporal regions during perturbation speech is consistent with previous results from studies of auditory feedback disruption, including delayed auditory feedback (Hirano et al, 1997;Hashimoto and Sakai, 2003), pitch perturbation (McGuire et al, 1996;Zarate and Zatorre, 2005;Fu et al, 2006) and noise masking (Christoffels et al, 2007) Numerous lines of evidence support the hypothesis that the expected consequences of articulation and resulting auditory feedback are compared in posterior temporal cortex (see Guenther et al, 2006 for detailed discussion). Portions of posterior left PT and lateral pSTg bilaterally have been shown to respond during both speech perception and speech production in several studies (Hickok et al, 2003;Buchsbaum et al, 2005). Bi-directional functional connections between inferior frontal and posterior temporal cortex have been demonstrated in vivo using cortico-cortical evoked potentials in humans (Matsumoto et al, 2004).…”

Neural mechanisms underlying auditory feedback control of speech

The neural substrates underlying auditory feedback control of speech were investigated using a combination of functional magnetic resonance imaging (fMRI) and computational modeling. Neural responses were measured while subjects spoke monosyllabic words under two conditions: (i) normal auditory feedback of their speech, and (ii) auditory feedback in which the first formant frequency of their speech was unexpectedly shifted in real time. Acoustic measurements showed compensation to the shift within approximately 135 ms of onset. Neuroimaging revealed increased activity in bilateral superior temporal cortex during shifted feedback, indicative of neurons coding mismatches between expected and actual auditory signals, as well as right prefrontal and Rolandic cortical activity. Structural equation modeling revealed increased influence of bilateral auditory cortical areas on right frontal areas during shifted speech, indicating that projections from auditory error cells in posterior superior temporal cortex to motor correction cells in right frontal cortex mediate auditory feedback control of speech.

Objective Computation of a pre-articulatory phonological representation (phonological access, or phonological retrieval) is an essential process in speech production whose neural localization is not clear. This study combined a specific behavioral measure of phonological access and multivariate voxel-based lesion-symptom mapping (VLSM) in a series of left hemisphere stroke patients to identify brain regions critical for this process. Methods Phonological access was assessed in 40 chronic ischemic stroke patients using a silent rhyming task to avoid confounds with motor planning and articulation deficits. Additional covariates were incorporated in the VLSM analysis to control for orthographic and working memory demands of the rhyming task, and for age, education, and total lesion volume. The resulting t-statistic maps were thresholded at voxel-wise p < .001 and cluster-corrected at a family-wise error of p < .05. Results Phonological access impairment was correlated with damage to a focal region of cortex and white matter caudal to the posterior sylvian fissure, which included the posterior supramarginal gyrus and adjacent anterior angular gyrus, planum temporale, and posterior superior temporal gyrus. No correlation was observed with Broca’s area, insula, or sensorimotor cortex. An additional VLSM showed no correlation between damage in this posterior perisylvian region and spoken word comprehension. Interpretation This is the first demonstration of a specific lesion correlate for phonological access impairment. Although this posterior perisylvian region overlaps with some versions of the classical Wernicke area, the present results demonstrate its involvement in pre-articulatory phonological production rather than speech perception or lexical-semantic processes.
