Most of current concepts for a visual prosthesis are based on neuronal electrical stimulation
at different locations along the visual pathways within the central nervous system. The …

Impairments of vision and hearing are highly prevalent conditions limiting the quality of life
and presenting a major socioeconomic burden. For a long time, retinal and cochlear …

Karlheinz Brandenburg and Mark Kahrs With the advent of multimedia, digital signal
processing (DSP) of sound has emerged from the shadow of bandwidth limited speech …

Speech understanding and subjective preference for three different speech coding
strategies (spectral peak coding [SPEAK|, continuous interleaved sampling [CIS], and …

This paper presents an 8 channel energy-efficient neural stimulator for generating charge-
balanced asymmetric pulses. Power consumption is reduced by implementing a fully …

Objectives: To assess the sensitivity of two bilateral cochlear implant users to interaural level
and time differences (ILDs and ITDs) for various signals presented through the auxiliary …

A wealth of knowledge about different types of neural responses to electrical stimulation has
been developed over the past 100 years. However, the exact forms of neural response …

High stimulation rates in cochlear implants (CI) offer better temporal sampling, can induce
stochastic-like firing of auditory neurons and can increase the electric dynamic range, all of …
