Abstract: The present disclosure relates to a method for determining stimulation parameters for a neuroprosthetic device performed by a processor of the device. Based on (i) a desired spatial pattern of neural activity, the processor determines stimulation parameters for an array of electrodes of the neuroprosthetic device. The processor determines the stimulation parameters such that a difference between (i) the desired spatial pattern of neural activity and (ii) an estimated spatial pattern of neural activity is optimised. The estimated spatial pattern of neural activity is an estimate of a response of a target neural tissue to being stimulated by the neuroprosthetic device based on the stimulation parameters. This method allows higher resolution stimulation and allows electrode arrays with higher electrode density to be usefully employed.

Abstract: A method generating electrical stimuli by an auditory prosthesis (1;1?;1?) including an array of stimulation devices in response to an incoming acoustic signal, the method including determining stimulation devices to be activated within the array and activation times for those electrodes; and applying a temporal adjustment (12) to the activation times such that activation of electrodes representing lower-amplitude components of the signal is delayed relative to activation of a proximate device representing a higher-amplitude component of the signal.

Abstract: A method for processing sound signals to generate electrical stimuli for an auditory prosthesis electrode array including a plurality of electrodes, the method including: deriving (10) one or more filtered representations (FIGS. 3 and 4) of an incoming audio signal; and, generating (11) a series of spikes from each filtered signal representation to directly control electrode stimulation. Each spike has a temporal position based upon an instant at which the filtered signal representation crosses a predetermined threshold (ÿ;0).
