Abstract(in English) For neural diseases, clinical trials of the treatments/prostheses with the functional electric stimulation have been widely performed in recent years. In those cases, it is critical to use the minimum amounts of current/charge to stimulate the target neurons, in order to guarantee their safety. However, the wave form, which is used as electric stimulation to clinical, is simple rectangular wave pulse and is not optimal about its amounts of current, wave form and position of stimulus. Therefore, in this study, we analyzed quantitatively on the optimization of electrical stimulus at the single neuron level by computer simulation used biophysics models of neurons. As a result, it was shown that the amounts of current/charge required for evoking spike firings of the model cells can be reduced by optimally adjusting the parameters of stimulation pulse waveforms, and that it was very more important to select the three dimensional position of the stimulation electrode optimally.
