The course includes selected methods of the biomedical modeling and data analysis using relevant information systems. Custom theme includes a description of the acquisition and analysis of multichannel biomedical data and images with their subsequent modeling. The focus of the course is on mathematical data processing and well-researched assessment results. It allows students to unify view on the biological data processing by using computer technology and database systems.

Last update: Pátková Vlasta (20.04.2018)

Students completing the course will be able to model basic biological processes at the single-cell level, interactions of cells group, organs and the whole organism. For the modeling of biological processes in space and time they will be able to process 1D, 2D and 3D signals. To test the response of the organism to external stimuli they will be able to prepare experiments on the Vernier equipment (for sensing temperature, pressure, ECG, ventilation parameters and muscle activity) and Walter (to capture visual and cognitive evoked potentials and EEG).
