Dorsolateral prefrontal cortex activations in overt verbal and sensorimotor tasks

Task	x	y	z	Location	Study
Overt verbal
Verbal fluency	−43	+29	+20	Brodmann area 45/46	PET, Frith et al. (4)
Verbal fluency	−46	+24	+18	Brodmann area 45	fMRI, Phelps et al. (9)
Verb generation	−43	+28	+13	Brodmann area 45	PET, Raichle et al. (10)
Sensorimotor
Finger movement	−35/+35	+39/+26	+21/+24	Brodmann area 9/46	PET, Frith et al. (4)
Finger movement	−30/+37	+35/+27	+28/+29	Brodmann area 9/46	fMRI, present study
Joystick movement	−34/+34	+35/+36	+28/+28	Brodmann area 9/46	PET, Deiber et al. (11)

The tasks in the Frith et al. (4) study, Phelps et al. (9) study, and the present study are the sensorimotor and verbal fluency tasks that have been described in the text in great detail. The task in the Raichle et al. (10) study is a verb-generation task, whereas the task in the Deiber et al. (11) study is a random joystick movement task.
