1. A biological signal display apparatus comprising:
- a stimulator configured to stimulate a living body;
a display; and
at least one central processing unit configured to;
control the stimulator to sequentially apply stimuli to the living body, the sequentially applied stimuli having a predetermined value;
receive evoked signals of evoked responses to the sequentially applied stimuli;
analyze the evoked signals to determine values of the evoked responses; and
control the display to maintain on the display a bar graph of laterally rectangular bar-shaped images corresponding to the evoked responses, the laterally rectangular bar-shaped images disposed in vertically arranged columns along an abscissa of the bar graph and heights of the vertically arranged columns of laterally rectangular bar-shaped images along an ordinate of the bar graph corresponding to values of the evoked responses, a first vertically arranged column among the vertically arranged columns of laterally rectangular bar-shaped images comprising;
a first laterally rectangular bar-shaped image corresponding to a maximum value of the evoked responses,the first laterally rectangular bar-shaped image including a first side of a first length, along the abscissa of the bar graph, andthe first laterally rectangular bar-shaped image including a second side of a second length smaller than the first length, along the ordinate of the bar graph; and
a second laterally rectangular bar-shaped image corresponding to a present value of a current evoked response to stimuli most recently applied to the living body,wherein the first laterally rectangular bar-shaped image and the second laterally rectangular bar-shaped image are simultaneously displayed in the first vertically arranged column,wherein the first laterally rectangular bar-shaped image and the second laterally rectangular bar-shaped image are vertically stacked in the first vertically arranged column such that the second laterally rectangular bar-shaped image is displayed below the first laterally rectangular bar-shaped image along the ordinate of the bar graph, andwherein the first laterally rectangular bar-shaped image and the second laterally rectangular bar-shaped image include the same coordinates along the abscissa of the bar graph;
wherein the at least one central processing unit is further configured to control the display to display a second vertically arranged column, among the vertically arranged columns of laterally rectangular bar-shaped images, adjacent to the first vertically arranged column along the abscissa of the bar graph.

Abstract
A biological signal display apparatus includes: a stimulation unit which performs stimulation on a living body; a measurement unit which measures an evoked response evoked by the stimulation; a calculator which calculates a feature amount of the evoked response; a display unit; and a display controller which, based on the feature amount calculated by the calculator, displays a bar-shaped image on the display unit, each time when the stimulation is performed, the bar-shaped image corresponding with the evoked response on the display unit.
