An in vivo experiment to control a left ventricular assist device (an
artificial heart system) using information from the sympathetic nervous system.
The electrode is expected to be fixed to the cardiac sympathetic nerve. However, at
the moment, the electrodes have been attached to the left vagal and sympathetic
nerve trunk at the neck for technical reasons

being used in our project to develop an artificial arm (or leg) system that is
capable of sensing mechanical stimuli and then transferring these stimuli to
the subject, so that the subject can experience the stimuli as the correspon-
ding somatic sensations. First, we will explain the concept and technique used
to evoke somatic sensations artificially by electrically stimulating a sensory
nerve fiber from a single mechanoreceptor unit. Next, we will discuss how the
properties of an evoked sensation are affected when electrical stimulations
