Content, Learning Outcome and Preconditions
Content
The lecture covers the theoretical foundations of neuroprostheses, which are solved numerically in the practical course. As the underlying principle of all neuroprostheses is the electrical excitation of neurons, we will cover this topic in depth using cochlea implants as an example.
In the practical computer laboratory (2SWS), which complements the lecture (2SWS), we implement a computer model of a cochlea implant and model how it will stimulate the auditory nerve.
Topcis:
- Overview neuroimplants
- numerical solution of linear and nonlinear differential equations
- electrical models of cells and neurons
- derivation and solution of the cable equation for nerve fibers (axons)
- simulation of the electrical excitation of nerve fibers (axons)
- simulation of electrical field spread in the body
- anatomy and function of the hearing organ
- coding of sound in the auditory nerve
- implementation of a coding strategy for a cochlear implant
- electrochemistry of electrodes, biocompatibility and foreign body reactions

Module Exam
Description of exams and course work
The written exam (60 Min) will test the analysis of the basic function of neurons, the hearing system and of cochlear implants. In addition, the ability to evaluate the electrical excitation of neurons by neuropostheses will be tested.
In the practical course the skill to develop computer models of neurons and neuroprostheses will be tested. (Motto: I have fully understood only what I can build.)
This will be done by evaluating of the solutions of the exercises as laboratory grade.
Grading:
- 100% exam
The submitted solution of problems from the exercise are evaluated (mid-term exam), if passed it improves the final grade by 0.3
