Many different cortical areas are thought to be involved in the process of selecting motor responses, from the inferior frontal gyrus, to the lateral and medial parts of the premotor cortex. The objective of the present study was to examine the neural underpinnings of motor response selection in a set of overt language production tasks. To this aim, we compared a sentence repetition task (externally constrained selection task) with a sentence generation task (volitional selection task) in a… 

Sensory-Motor Integration during Speech Production Localizes to Both Left and Right Plana Temporale

The present human functional magnetic resonance imaging study used univariate and multivariate analyses to investigate both overt and covert (internally generated) propositional and nonpropositional speech, finding activity in response to overt, but not covert, speech was present in bilateral anterior PT.

Speech networks at rest and in action: interactions between functional brain networks controlling speech production.

The data demonstrate complex interactions of large-scale brain networks controlling speech production and point to the critical role of the LMC, IPL, and cerebellum in the formation of speech production network.

FMRI Studies of the Supplementary Motor Area and the Premotor Cortex

Functional maps resulting from comparison of the motor tasks with REST reveal activation in primary sensorimotor cortex, medial and lateral premotor areas, cingulate cortex, and parietal cortex, reflecting the functional heterogeneity of these areas suggested by previous studies.

Relative Shift in Activity from Medial to Lateral Frontal Cortex During Internally Versus Externally Guided Word Generation

Right-handed native English speakers performed three word generation tasks varying in the amount of internal guidance and a repetition task during functional magnetic resonance imaging (fMRI) to test Goldberg's hypothesis that as language output changes from internally to externally guided production, activity shifts from supplementary motor area to lateral premotor areas, including Broca's area.

From language comprehension to action understanding and back again.

The results are among the first to reveal, in the human brain, a functional specialization within the ventral premotor cortex (PMv) for observing actions and for observing objects, and a different organization for processing sentences describing actions and objects.

This chapter reviews the findings of 58 word production experiments using different tasks and neuroimaging techniques and includes a discussion of the available evidence on syntactic production, self-monitoring, and the time course of word production.
