Abstract

To develop neuroprostheses that will provide the nervous system with artificial sensory input through the sensory nerves to which they will be connected, on one hand we have to determine how external stimuli are represented, coded and transmitted by the Nervous System, how neurons and neuronal ensembles process, encode and transmit perceptual information. On the other we need to know how the central nervous system reacts to the implanted neuroprostheses and quantify its anatomic and functional alterations due to the artificial input it receives from our devices. Here we present mathematical and electrophysiological methods for signal acquisition, analysis, and information coding in the tactile sensory system that include a wavelet and principal component analysis-based method for neural signal analysis and different types of frequency-based signal processing and coding performed simultaneously by the sensory neurons. Finally we present a quantitative morphological study of the effects of the neuroprosthetic stimulation using a stereological approach.
