[Use of ultrasound in movement studies].
This work shows how to use ultrasounds to record micromammals motor activity. It furnishes at the same time the incorporation of an accumulator which records the motor activity above a minimum which is higher than the one produced by the machine itself, thus measuring exclusively the animal activity.
