Abstract: Disclosed are methods for regulating blood pressure in a subject which include administering a first induction stimulus effective to sensitize brainstem baroreflex neurons of a subject for a period of time in the range of about 10-15 hours thereby producing an enhanced baroreflex in the subject, wherein the enhanced baroreflex is characterized in that a threshold blood pressure for generating a depressor response is lower than prior to induction stimulus administration, the depressor response in the subject is larger than prior to induction stimulus administration or both the threshold blood pressure for generating a depressor response is lower than prior to induction stimulus administration and the depressor response in the subject is larger than prior to induction stimulus administration. An induction stimulus has diminished effectiveness to sensitize neurons in the nucleus tractus solitarius of the subject in the presence of an NMDA receptor antagonist.

Abstract: A system and method for the operant conditioning of subjects using biofeedback includes means to measure a variable condition, such as posture, which is controllable by the subject. The apparatus sets criteria which, if not met, may result in a negative reinforcement, such as unpleasant audio tone or, if the criteria is met, will reward the subject. The criteria is automatically adjusted, upwards or downwards, in accordance with the subject's history of reaching, or not reaching, the criteria.The device includes a programmed microcomputer whose inputs include digital converters and which simultaneously adjusts the criteria and which controls the stimuli means, such as a tone generator and its speaker.

The apparatus sets criteria which, if not met, may result in a negative reinforcement, such as unpleasant audio tone or, if the criteria is met, will reward the subject. The criteria is automatically adjusted, upwards or downwards, in accordance with the subject's history of reaching, or not reaching, the criteria.One embodiment is a device for the training of patients with idiopathic scoliosis (curvature of the spine), as a replacement for a brace. The device includes two cables, one about the chest to measure breathing and the other longitudinally about the trunk to measure spine length. The variable lengths of the cables are converted to digital signals by rotary-to-digital converters.
