A computer implemented method of suggesting tasks to a user based upon their graphical user interface browsing behavior is provided. The electric wires include a pair of first and second electric wires each having an end portion where the electric conductor is not covered by the insulating coat. The hypotheses may be ranked based on varying degrees of certainty, and an adaptive response may be generated for the user. The nerve blocking apparatus is activated to block neural propagation along the nerve. The differences obtained by the comparison are compared with selected threshold values.
