OVERVIEW

Electrophysiology includes various experimental techniques for the investigation of membrane ion channels and transporters and the study of the electrical signals associated with them.

AIMS AND CONTENT

LEARNING OUTCOMES

The course aims to introduce the most important electrophysiological techniques, namely the patch-clamp technique, in various configurations, and the two-electrode voltage-clamp technique (TECV) applied to Xenopus oocytes. The course will examine the related theoretical aspects and will present the functional and structural features of the main families of ionic channels and electrogenic transporters localized on both plasma and intracellular membranes.

AIMS AND LEARNING OUTCOMES

Attendance and active participation in the proposed educational activities (lectures and laboratory activities) and individual study will enable the student to:

- to know the theoretical and experimental aspects of the heterologous expression of ion channels and transporters in Xenopus oocytes and of the relative technique of the double microelectrode voltage-clamp (TECV);

- to know the theoretical and experimental aspects of the patch-clamp technique.
