fMRI: Language tasks
This page contains links to a series of pages relating to clinical fMRI for language lateralization. Evidence supporting some key paradigms, and downloads for programmed versions of the tasks themselves. These should be used only by individuals with sufficient training, such as neuropsychologists with expertise in fMRI, radiologists, clinical neuroscientists, or neurologists with equivalent expertise. Clinical fMRI is most likely to be optimal when individuals from multiple relevant professions are involved. All tasks here run on Neurobehavioral Systems' Presentation, in Windows on a PC or a Mac running a virtual machine. You can download the tasks, as part of the Open Multilingual fMRI battery, here.
Guidelines for clinical fMRI
Details on professional organization's guidelines on the clinical use of fMRI, on what those completing clinical fMRI actually do, how clinicians interpret fMRI, and other relevant information.
