Method for reversible chemical modulation of neural activity

A method of modulating neural activity comprising the steps of:

• producing a reversible conduction block in a peripheral neural structure of a subject with a chemical blocking agent while the subject is in a low activity state;
• reversing the reversible conduction block in the peripheral neural structure of the subject to permit conduction in the peripheral neural structure when the subject is in a higher activity state by applying a reversing stimulus configured to counter the chemical blocking agent used to produce the reversible conduction block in the peripheral neural structure of the subject;
• and
• repeating the steps of producing a reversible conduction block in a peripheral neural structure of a subject while the subject is in a low activity state and reversing the reversible conduction block in the peripheral neural structure of the subject to permit conduction in the peripheral neural structure when the subject is in a higher activity state.
