Course entry requirements:

Knowledge of anatomy and especially physiology, electrophysiology, physical chemistry, biochemistry, modeling and simulation, and skills in Matlab and Simulink.

Credit is conditional on attendance. Only one excused absence for serious reasons is possible. And passing two midterm exams per semester. Each test of 10 questions of 1 point each with three answer choices, only one correct each time) with a given number of points. The final grade will be the average of the sum of the scores on both tests and must be greater than or equal to 50% of the total score on both tests. It is not possible to take the exam without obtaining the credit and entering it into the CTU KOS IS.

The exam consists of a written test, where there is a combined answer option of ABC type (always one correct) - 1 point, i.e. 0 or 1 point and an option where it is necessary to answer in writing (open questions) - 5 points, i.e. from 0 to 5 points (important questions). There are 32 questions in total, including 20 MCQs (abc) of 2 marks each and 12 open questions of 5 marks each. Correct answer depending on type 0 to 5 marks, marking multiple answers means 0 marks, no answer means 0 marks, wrong answer means zero marks. Minimum 50 points, maximum 100 points. Assessment of the test according to the ECTS. Total time allotted for the test is 60 minutes. After correcting the test, oral retesting to a better grade is possible if the test result is on the borderline of the grading grades (typically by 2 points).
