Organizational part - 5 minutes. Rollcall of the students and elucidation the reasons of the absence of students, checking of theRollcall of the students and elucidation the reasons of the absence of students, checking of the conspectus. Number of forming competencies:knowledge, practical skills. Main questions of the theme: 45 minutes 1. What methods are used for the registering of EEG? 2. The main types of electrical activity of pyramidal neurons. 3. What modern models are used in EEG? 4. What value does the interrelation of electrical activity of pyramidal neurons have? 5. What is the important condition for EEG genesis? Break - 10 minutes Learning and teaching methods: - analysis and discussing of main and control questions; - solving of standard and situational problems; - testing; - correction of mistakes. Methods of the control of formed at classes competencies: - checking of the solution of standard and situational problems; - opinions exchanging at the studying of educational material; - testing on a computer (a student has to give the answers for test questions that contain minimal knowledge and skills – main definitions, theoretical questions of the theme). Students’ independent work - 30 minutes Explain the context and find the ways of solving the problems. Transform the formula and convert the unit of physical quantities to the International System of Units.
