abstract = {A speech-action-repository (SAR) or “mental syllabary”
has been proposed as a central module for sensorimotor
processing of syllables. In this approach, syllables
occurring frequently within language are assumed to be
stored as holistic sensorimotor patterns, while non-frequent
syllables need to be assembled from sub-syllabic units.
Thus, frequent syllables are processed efficiently and
quickly during production or perception by a direct
activation of their sensorimotor patterns. Whereas several
behavioral psycholinguistic studies provided evidence in
support of the existence of a syllabary, fMRI studies have
failed to demonstrate its neural reality. In the present
fMRI study a reaction paradigm using homogeneous vs.
heterogeneous syllable blocks are used during overt vs.
covert speech production and auditory vs. visual
presentation modes. Two complementary data analyses were
performed: (1) in a logical conjunction, activation for
syllable processing independent of input modality and
response mode was assessed, in order to support the
assumption of existence of a supramodal hub within a SAR.
(2) In addition priming effects in the BOLD response in
homogeneous vs. heterogeneous blocks were measured in order
to identify brain regions, which indicate reduced activity
during multiple production/perception repetitions of a
specific syllable in order to determine state maps.
Auditory-visual conjunction analysis revealed an activation
network comprising bilateral precentral gyrus and left
inferior frontal gyrus (area 44). These results are
compatible with the notion of a supramodal hub within the
SAR. The main effect of homogeneity priming revealed an
activation pattern of areas within frontal, temporal, and
parietal lobe. These findings are taken to represent
sensorimotor state maps of the SAR. In conclusion, the
present study provided preliminary evidence for a SAR.},
