“…These regions have consistently been activated in verbal working memory studies encouraging verbal rehearsal [3,5]. In contrast, other classical regions associated with verbal rehearsal -Broca's area and left posterior parietal cortex -were not found to be specifically activated during maintenance of words [29].…”

“…Nominal issues aside, support for a posterior localization could be attributed to a constellation of effects pertaining to aspects of speech or phonology that localize to posterior STG/ STS (69), for instance: speech production (101-108), phonological/articulatory working memory (109,110), reading (111)(112)(113) [putatively attributable to orthography-to-phonology translation (114)(115)(116)], and aspects of audiovisual language processing (117)(118)(119)(120)(121)(122). Although these findings relate to aspects of speech and phonology, they do so in terms of multisensory processing and sensorimotor integration and are not the key paradigms indicated by computational theory for demonstrating the presence of pattern recognition networks (8)(9)(10)(11)(12)123).…”

Spoken word recognition requires complex, invariant representations. Using a meta-analytic approach incorporating more than 100 functional imaging experiments, we show that preference for complex sounds emerges in the human auditory ventral stream in a hierarchical fashion, consistent with nonhuman primate electrophysiology. Examining speech sounds, we show that activation associated with the processing of short-timescale patterns (i.e., phonemes) is consistently localized to left mid-superior temporal gyrus (STG), whereas activation associated with the integration of phonemes into temporally complex patterns (i.e., words) is consistently localized to left anterior STG. Further, we show left midto anterior STG is reliably implicated in the invariant representation of phonetic forms and that this area also responds preferentially to phonetic sounds, above artificial control sounds or environmental sounds. Together, this shows increasing encoding specificity and invariance along the auditory ventral stream for temporally complex speech sounds.functional MRI | meta-analysis | auditory cortex | object recognition | language S poken word recognition presents several challenges to the brain. Two key challenges are the assembly of complex auditory representations and the variability of natural speech (SI Appendix, Fig. S1) (1). Representation at the level of primary auditory cortex is precise: fine-grained in scale and local in spectrotemporal space (2, 3). The recognition of complex spectrotemporal forms, like words, in higher areas of auditory cortex requires the transformation of this granular representation into Gestalt-like, object-centered representations. In brief, local features must be bound together to form representations of complex spectrotemporal contours, which are themselves the constituents of auditory "objects" or complex sound patterns (4, 5). Next, representations must be generalized and abstracted. Coding in primary auditory cortex is sensitive even to minor physical transformations. Object-centered coding in higher areas, however, must be invariant (i.e., tolerant of natural stimulus variation) (6). For example, whereas the phonemic structure of a word is fixed, there is considerable variation in physical, spectrotemporal form-attributable to accent, pronunciation, body size, and the like-among utterances of a given word. It has been proposed for visual cortical processing that a feed-forward, hierarchical architecture (7) may be capable of simultaneously solving the problems of complexity and variability (8-12). Here, we examine these ideas in the context of auditory cortex.In a hierarchical pattern-recognition scheme (8), coding in the earliest cortical field would reflect the tuning and organization of primary auditory cortex (or core) (2, 3, 13). That is, single-neuron receptive fields (more precisely, frequency-response areas) would be tuned to particular center frequencies and would have minimal spectrotemporal complexity (i.e., a single excitatory zone and one-to-two inhibitory side bands). ...

“…Included in this network is a region in the left posterior Sylvian fissure at the parietal-temporal boundary, area Spt 1 . Area Spt appears to be functionally and anatomically connected with a frontal area known to be important for speech (area 44) (Buchsbaum et al, 2001;Buchsbaum, Olsen, Koch, & Berman, 2005a;Catani, Jones, & Ffytche, 2005;Galaburda & Sanides, 1980;Hickok & Peoppel, 2004) and the area Spt region, when disrupted via lesion or electrical stimulation, results in speech production deficits (Damasio & Damasio, 1980;Anderson et al, 1999). For these reasons, and also because of its anatomical location, area Spt has been hypothesized to be a sensory-motor integration area analogous in function to the sensory-motor integration areas previously identified in the PPC (Andersen, 1997;Colby & Goldberg, 1999).…”

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.
