Abstract

Neuroimplants: Theory, experiment and clinical application The application of neuroimplants has been a dream for decades in order to improve or substitute an entire sensual system. Nowadays clinically relevant neuroimplants for sensory systems are available only to aid the auditory system and are namely cochlear implants (CI), auditory brainstem implants (ABI) and auditory midbrain implants (AMI). Despite the tremendous success of cochlear implants, patients still suffer from difficulties in acoustically adverse environment in understanding speech and in the appraisal of music. One reason for this is that cochlear implants lack the proper provision of temporal information. Therefore, research focuses on the improvement of temporal information transfer. Simulation results (Bahmer and Langner, 2006 I & II, 2009) do imply that temporal information transfer may be improved by broadband electrical stimulation. Rate pitch discrimination experiments in CI-users show an improvement in the broad electrical field condition but this effect was not statistically significant due to the high variability in subject performances (Bahmer and Baumann, 2012). Thus, we developed physiological test setups which cope with electrical artifacts induced by the electrical stimulation of the implant (Bahmer and Baumann, 2008, 2010).
