1. A method for successively presenting neural stimuli on an electrode array having one or more electrodes, comprising:
- determining a stimulus set for one or more periods;
analyzing each proposed stimulus set using a predetermined instruction set which is adapted to locate factors indicative of a likely masking effect;
if masking effects are detected,deleting at least one of said stimuli in said stimulus set, andadding at least one alternative stimuli to said stimulus set; and
presenting the stimuli via said electrode array to a neural structure.

Abstract
A method and device are disclosed for neural stimulation with improved power consumption and/or effectiveness. The stimulus generator is arranged, for example via a look up table, to recognize proposed stimuli which will be masked by earlier or simultaneous stimuli. Such masked stimuli are either deleted, or replaced by another stimulus.

7. A neural stimulator device comprising:
-
a stimulus generation device for generating stimulus sets, said stimulus sets for delivery at an electrode array for operatively presenting stimuli to neural structures, each said stimulus set relating to one or more stimulation periods; and processing means for analyzing each stimulus set using a predetermined instruction set in order to locate factors indicative of a likely masking effect, and if it is determined that a masking effect is likely, for altering said stimulus set by deleting at least one of said stimuli in said stimulus set, and adding at least one alternative stimuli to said stimulus set; and means for presenting the stimuli via said electrode array to a neural structure. - View Dependent Claims (8, 9, 10, 11, 12)
