Description

This Examcard provides a full Neuro-exam including a T2 measurement, an anatomical underlay, a functional, contrast perfusion, and diffusion tensor study, as well as a high-resolution 3D T1 weighted measurement with full brain coverage.

 

fMRI paradigms

With this ExamCard the following fMRI paradigms may be used to visualize brain activity in an activation task versus a baseline task. For these paradigms 10 dynamics are used both for the "rest" and the "activation" period.

- Motor task (finger tapping, lip pouting, toe movements) versus rest.

- Complex motor task (random order finger-thumb opposition) versus simple motor task (fixed order finger-thumb opposition) to activate higher order motor areas.

- Visual task (eyes open, eyes blinking) versus eyes closed.

- Language task (word generation or verb to noun generation) versus baseline (e.g. tone listening or counting numbers 1-10). Avoid "rest" as baseline, since this might induce automatic rehearsal of the task during the baseline condition.

 

Within the ExamCard, for all scans, text and images are provided. Within the fMRI protocol the fMRI paradigms and IViewBold analysis are further described.
