Title
(EN) USING INTERACTION TO MEASURE NEURAL EXCITATION
(FR) UTILISATION D'UNE INTERACTION POUR MESURER UNE EXCITATION NEURALE
Abstract
(EN)
Assessment of neuron excitation is implemented by quantifying the interaction between focused and unfocused stimulation applied to a cochlear array. By applying focused and unfocused stimulation to the electrode array and comparing the difference in the responses to the two types of stimulation the interaction may be determined. The magnitude of the interaction may be related to neural excitation and using this data a neural excitation profile may be determined.
(FR)
L'invention porte sur l'évaluation d'une excitation de neurone qui est mise en œuvre par la quantification de l'interaction entre des stimulations focalisée et non focalisée appliquées à un réseau cochléaire. Par l'application de stimulations focalisée et non focalisée au réseau d'électrodes et par la comparaison de la différence des réponses des deux types de stimulation, l'interaction peut être déterminée. L'amplitude de l'interaction peut être apparentée à une excitation neurale et à l'aide de ces données, un profil d'excitation neurale peut être déterminé.
