The cortical dynamics of speaking: present shortcomings and future avenues

Kristof Strijkers, Albert Costa
2016 Language, Cognition and Neuroscience  
According to the dominant neurocognitive model of word production this is achieved in a sequential fashion where each of the linguistic components involved in speaking has its specific time-course and  ...  In this opinion piece we raise three critical issues aimed at questioning the strict feedforward and serial conceptualization of the spatiotemporal dynamics engendering word production.  ...  upon our knowledge about the spatiotemporal dynamics of speaking.  ...

The Infrastructure of the Language-Ready Brain [chapter]

Peter Hagoort, David Poeppel
2013 Language, Music, and the Brain  
The fi rst section outlines a selection of the major constituent operations, from fractionating the input into manageable units to combining and unifying information in the construction of meaning.  ...  Finally, in keeping with the spirit of the volume, some possible relations are highlighted between language and music that arise from the infrastructure developed here.  ...  Control operations recruit another part of the frontal lobe (in pink) and the anterior cingulate cortex (not shown in the fi gure).  ...
