Functional MRI investigation of verbal selection mechanisms in lateral prefrontal cortex
2008
NeuroImage
Preserved Fulltext
The current functional MRI study attempts to resolve this controversy by investigating verbal response and semantic selection in the same participants. ...
These results suggest that response and semantic selection may be distinct cognitive processes mediated by different regions of lateral PFC; but both of these selection processes rely on cognitive mechanisms ...
