Learning goals

The objective of this curricular unit is to teach the fundamentals of bioelectricity, especially the electrical properties of nervous cells on the formation, propagation and transmission of the nervous impulse and other excitable cells namely sensory and muscle cells.

In addition this curricular unit is also intended to provide students with an overview of the current state of knowledge concerning the main approached subjects and their physical correspondents. Other aim is that students develop their ability to do research and communicate orally and in writing.

Syllabus

1. Introduction to bioelectrical phenomena.

2. Structure and functions of the nervous cell.

3. Diffusion and transportation across membranes.

4. Resting potential of the membrane.

5. Electrical properties of the excitable membrane.

6. Functional properties of dendrites.

7. Action potential and Hodkin-Huxley model.

8. Gating chains and mechanisms.

9. Different ion channels which are dependent on the potential.

10. Molecule structure and individual channel chains.

11. Synaptic transmission: pre-and postsynaptic mechanisms.

12. Synaptic plasticity.

Teaching method

Theoretical classes mainly using audio-visual media and tutorial classes will be delivered. In these classes the themes of the summary assignments and their specific characteristics will be established. In addition, methods of study and methods for the presentation of the assignments will be discussed including the acquisition and reading of the bibliography and the computer tools to be used.
