Functional MRI investigation of verbal selection mechanisms in lateral prefrontal cortex

Irene E. Nagel, Eric H. Schumacher, Rainer Goebel, Mark D'Esposito
2008 NeuroImage  
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  ...  Acknowledgements This work was supported by grants from the National Institute of Health (MH63901 and NS40813) and the Veterans Administration.  ...
