The contribution(s) of the insula to speech production: a review of the clinical and functional imaging literature

A relatively small area at the junction of insular and opercular cortex was found sensitive to the phonetic-linguistic structure of verbal utterances, a strong argument for its engagement in articulatory control processes.

Activation of right insular cortex during imaginary speech articulation

The current magnetoencephalography study, in which 12 participants were required to imagine vocalizing a phonogram after a visual cue, was designed to visualize the prearticulatory ‘automatic’ processes corresponding to the motor initiation, suggesting that motor control of speech proceeds from the insular regions.

A systems perspective on the effective connectivity of overt speech production

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.

Author ' s personal copy The somatotopy of speech : Phonation and articulation in the human motor cortex

A sizable literature on the neuroimaging of speech production has reliably shown activations in the orofacial region of the primary motor cortex. These activations have invariably been interpreted as

Task load modulates tDCS effects on language performance

The brain stimulation findings support the neuroimaging literature in that motor participation in phonological processing depends on task nature and show that tDCS effects are modulated by task load relative to the target.

Activity in regions sensitive to auditory speech is modified during speech production: fMRI evidence for an efference copy

Models of speech production postulate that, in order to facilitate rapid and precise control of articulation, the predicted auditory feedback is sent to the auditory system to be compared with

Enhanced insular connectivity with speech sensorimotor regions in trained singers: a resting-state fMRI study

The results of this study support the view that the insula plays a central role in the experience-dependent modulation of sensory integration within the vocal motor system, possibly by optimizing conscious and non-conscious aspects of salience processing associated with singing-related bodily signals.

Findings corroborate the assumption that the left insula supports the coordination of speech articulation and suggest that the right insula might mediate temporo-spatial control of vocal tract musculature during overt singing.
