- During the cued production of words, a temporal cascade of neural
400
- activity proceeds from sensory representations of words in the
401
- temporal cortex to their corresponding articulatory gestures in the
402
- motor cortex. Broca's area mediates this cascade through reciprocal
403
- interactions with temporal and frontal motor regions. Contrary to
404
- classNameic notions of the role of Broca's area in speech, while the
405
- motor cortex is activated during spoken responses, Broca's area is
406
- surprisingly silent. Moreover, when novel strings of articulatory
407
- gestures must be produced in response to nonword stimuli, neural
408
- activity is enhanced in Broca's area, but not in the motor cortex.
409
- These unique data provide evidence that Broca's area coordinates the
410
- transformation of information across large-scale cortical networks
411
- involved in spoken word production. In this role, Broca's area
412
- formulates an appropriate articulatory code to be implemented by the
413
- motor cortex.
