Narrative speech production: An fMRI study using continuous arterial spin labeling
2008
NeuroImage
Preserved Fulltext
Functional magnetic resonance imaging (fMRI) with continuous arterial spin labeling (CASL) was employed to monitor brain activation during narrative production of a semi-structured speech sample in healthy ...
We conclude that inferior frontal cortex serves as a top-down organizational resource for narrative production and demonstrate the feasibility of collecting extended speech samples using CASL perfusion ...
In this report, we use functional magnetic resonance imaging (fMRI) with continuous arterial spin labeling (CASL) to monitor regional brain activation during narrative speech production. ...
