Eligibility

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: Healthy right-handed persons aged 18-65 years.

Exclusion criteria

Exclusion criteria: Subjects who suffer from specific neurological or psychiatric disorders or injury to the upper extremities will be excluded. Subjects who cannot go in the MRI scanner are also excluded. With neurological disorders we mean disorders for which the consult of a medical specialist was necessary: epilepsia, severe brain injury and temporary paralysis. Exclusion criteria for the MRI are for example the presence of ferromagnetic material in or on the body, pregnancy or claustrophobia. (specifief in the questionnaire) Furthermore, subjects who are right-handed, but draw with their left hand are excluded. Also, subjects with an uncorrectable abnormality in visual acuity will be excluded.

Design outcomes

Primary

Measure	Time frame
Localisation of condition-related increase in cerebral activation in the medial and lateral premotor cortex. A voxel-based analysis of task-related cerebral activation (increased BOLD responses) will be performed using 'Statistical Parametric Mapping' (SPM8). In this way differences in medial and lateral premotor cortex activation between the different experimental conditions will be quantified. The number of 16 subjects is enough for a random effects analysis of the fMRI data.	—
