The course Medical Informatics and Perception focuses on perception theory in a biological and computer-simulation context. The course integrates medical informatics, physics, mathematics and perception theory. Central theme is signal processing, by computer and by biological systems: perception.
We treat human vision and hearing in detail from a neurophysiological to a mathematical modelling level. The level of depth goes to the study of hearing as a (nonlinear) system capable to analyse the incoming sounds by Fourier Transform, and the visual system as a system extracting (multiscale) derivatives from the retinal images. We study the auditory and visual system as a process.
Both lecture hall presentations and computerlabs are based on Mathematica as an interactive toolkit. One of the objectives is to appreciate and get working knowledge of high-level easy-to-use computer simulation tools.

The course Medical Informatics and Perception is a blockcourse of one month for first year Medical Biology students at Utrecht University, the Netherlands. Additional to the lectures, are fourteen computer lab sessions.
The course is well received - the computer labs are especially vivid meetings. Students quickly learn to appreciate Mathematica's possibilities, which is useful as they will use it in later years' courses.
Topics:
- Neural signal processing
- Eye Physics
- Ear Physics
- Sensory system neuroanatomy
- Mathematics: complex numbers, integration, differentiation, partial differential equations
- Linear Systems, input/output relations
- Introduction to computers: hardware, operating systems, applications, networks, internet
- Fourier Transform and spectra
