Neurology: research

MMEP-coil on the head of a calveAt this moment research is performed for the utility of the magnetic motore evoked potential test (MMEP-test) in calves.

With the magnetic motor evoked potential test (MMEP-test), is a painless test which can be performed on the unsedated calf, it is possible to stimulate the brain through the scalp (Fig. 1) which then provokes a muscle activity in the 4 legs. The amplitude and the duration of this stimulation can be printed on a graph.

The puprose of the study is to describe normal reference values for healthy calves.

Electromyography (EMG) is a technique for recording the electrical activity in muscle by a machine. The electrical activity becomes audible and visible by the use of an electromyograph. With some muscle disorders these signals become abnormal.
