Trigeminal Brainstem Mapping

Study Description
Brief Summary:
To what extent the somatotopy of the 3 branches of the trigeminal nerve (V1,V2,V3) as well as the greater occipital nerve (GON) in the brainstem but also in the thalamus and the insula can be mapped using functional imaging and BOLD in humans is not known but might play an important role in imaging headache diseases. The aim is to map their somatotopy by random stimulation of V1, V2, V3 and the GON with painful electrical input during acquisition of BOLD-fMRI.

Outcome Measures
Primary Outcome Measures :
  1. Statistical Parametric Map calculated from the fMRI data on brainstem level [ Time Frame: through study completion, an average of 9 months ]

    At a statistical threshold of T-value 3 we will observe a somatotopical arrangement in the brainstem below the pons:

    Expected location for V1: within radius of 10 mm around the MNI coordinates (-1,-48,-75); Expected location for V2: within radius of 10 mm around the MNI coordinates (-4,-47,-69) Expected location for V3: within radius of 10 mm around the MNI coordinates (-1,-46,-66) Expected location for GON: within radius of 10 mm around the MNI coordinates (-1,-45,-64)


  2. Statistical Parametric Map calculated from the fMRI data in the thalamus [ Time Frame: through study completion, an average of 9 months ]

    At a statistical threshold of T-value 4 we will observe a somatotopical arrangement in the thalamus:

    Expected location for V1: within radius of 10 mm around the MNI coordinates (11,-5,6); Expected location for V2: within radius of 10 mm around the MNI coordinates (13,-11,5) Expected location for V3: within radius of 10 mm around the MNI coordinates (12,-10,5) Expected location for GON: within radius of 10 mm around the MNI coordinates (15,-12,-7)


  3. Statistical Parametric Map calculated from the fMRI data in the insula [ Time Frame: through study completion, an average of 9 months ]

    At a statistical threshold of T-value 4 we will observe a somatotopical arrangement in the insula:

    Expected location for V1: within radius of 10 mm around the MNI coordinates (38,-15,8); Expected location for V2: within radius of 10 mm around the MNI coordinates (37,-8,-5) Expected location for V3: within radius of 10 mm around the MNI coordinates (39,2,-11) Expected location for GON: within radius of 10 mm around the MNI coordinates (38,-12,-3)



Secondary Outcome Measures :
  1. Statistical Parametric Map calculated from the fMRI data in the cerebellum [ Time Frame: through study completion, an average of 9 months ]
  2. Statistical Parametric Map calculated from the fMRI data in the periaqueductal gray (PAG) [ Time Frame: through study completion, an average of 9 months ]
