Fig. 8. Schematic concept of future uses of heavy ion pulses for conveying "coded" 

 messages to the brain. The coding may occur by (a) magnetic deflection of beam in 

 predetermined sequence, e.g., scanning; (b) by passage of beam through absorbers of 

 predetermined profile to position the Bragg ionization peak where the stimulation 

 occurs; (c) by coding time sequence and intensity of pulses of beam; (d) by using 

 "feedback" information from periphery to change coded messages.
