Systems and methods for altering vestibular biology

A system for treating a subject, comprising:

• a) a sensor that collects information related to body position with respect to a gravitational plane;
• b) an electrotactile stimulator array configured to transmit a pattern of electrotactile stimulation to a subject's tongue;
• and c) a processor configured to:
• i) receive information from said sensor related to a subject's body position with respect to a gravitational plane;
• ii) convert said information into said pattern;
• and iii) transmit said pattern to said electrotactile stimulator to allow said electrotactile stimulator array to transmit said pattern of electrotactile stimulation to said subject's tongue.

A method for maintaining balance, comprising:

• a) measuring a subject's body position with a sensor that collects information related to body position with respect to a gravitational plane;
• b) displaying a visual object to said subject based on said body position by generating a said visual object from data collected by said sensor;
• c) providing a visual reference point to said subject;
• and d) having said subject maintain a position of said visual object with said visual reference point over a period of time under conditions such that said position corresponds to a balanced body position.
