Abstract

A method (40) and system (10) of presenting an electrophysiological signal, the method comprising receiving (41) the electrophysiological signal, extracting (42) different components from the received electrophysiological signal, processing (43) the different components to generate different audio signals corresponding to the respective different components, and audibly presenting (44) the different audio signals. Each component represents an activity of atleast one physiological unit.

Claims

1. A method (40) of presenting an electrophysiological signal, the method comprising:

receiving (41) the electrophysiological signal,

extracting (42) different components from the received electrophysiological signal, each component representing an activity of at least one physiological unit,

processing (43) the different components to generate different audio signals corresponding to the respective different components, and

audibly presenting (44) the different audio signals.

2. A method (40) of presenting an electrophysiological signal according to claim 1, wherein the processing (43) comprises applying different gains to the different audio signals.

3. A method (40) of presenting an electrophysiological signal according to claim 2, wherein the applying different gains and the audibly presenting the different audio signals are repeated at least once with different relative gains for the different audio signals.

4. A method (40) of presenting an electrophysiological signal according to claim 1, wherein the processing (43) comprises applying different filters to the different audio signals.

5. A method (40) of presenting an electrophysiological signal according to claim 1, wherein the processing (43) comprises assigning a position to each one of the different audio signals and the audibly presenting (44) comprises using 3D positional audio algorithms for presenting the audio signals as if coming from the respective assigned positions.

6. A method (40) of presenting an electrophysiological signal according to claim 1, wherein one component of the different components comprises a background noise.

7. A method (40) of presenting an electrophysiological signal according to claim 1, wherein one component of the different components comprises at least one individual action potential.

8. A method (40) of presenting an electrophysiological signal according to claim 1, wherein one component of the different components comprises multiple action potentials from a single physiological unit.

9. A support system (10) for assisting in reading an electrophysiological signal, the support system (10) comprising:

an input (11) for receiving the electrophysiological signal

a processor (12) being operative to

extract different components from the received electrophysiological signal, each component representing an activity of at least one physiological unit, and

generate different audio signals corresponding to the respective different components, and

an audio output (13, 30) for audibly presenting the different audio signals.
