Task-Related Modulation of Early Cortical Responses during Language Production: An Event-Related Synthetic Aperture Magnetometry Study

@article{citeulike:1732344, abstract = {We used whole-head magnetoencephalography measurements to investigate the spatiotemporal pattern of neural activity related to language production. Eight participants overtly responded by repeating aloud or vocalizing an internally generated verb to auditorily or visually presented nouns. Activity peaked within primary sensory (auditory or visual) cortices between 75 and 130 ms after stimulus onset, association cortices (inferior and superior temporal gyri) between 130 and 170 ms, and inferior frontal and premotor areas between 150 and 240 ms. Common to auditory and visual modalities, peak activity at about 220 ms was significantly larger in bilateral inferior frontal and left precentral regions when participants generated a verb than when they repeated a noun.
