abstract = {The aim of this study was to provide a computational system
model of effective connectivity in the human brain
underlying overt speech production. Meta-analysis of
neuroimaging studies and functional magnetic resonance
imaging data acquired during a verbal fluency task revealed
a core network consisting of Brodmann's area (BA) 44 in
Broca's region, anterior insula, basal ganglia, cerebellum,
premotor cortex (PMC, BA 6) and primary motor cortex (M1,
areas 4a/4p). Dynamic causal modelling (DCM) indicated the
highest evidence for a system architecture featuring the
insula in a serial position between BA 44 and two parallel
nodes (cerebellum/basal ganglia), from which information
converges onto the PMC and finally M1. Parameter inference
revealed that effective connectivity from the insular relay
into the cerebellum/basal ganglia is primarily task driven
(preparation) while the output into the cortical motor
system strongly depends on the actual word production rate
(execution). DCM hence allowed not only a quantitative
characterization of the human speech production network, but
also the distinction of a preparatory and an executive
subsystem within it. The proposed model of physiological
integration during speech production may now serve as a
reference for investigations into the neurobiology of
pathological states such as dysarthria and apraxia of
speech.},
