Electrophysiology is the study of the electrical properties of biological cells and tissues. This field of research focuses on measuring and analyzing the electrical activity of cells, particularly in the nervous and muscular systems. Electrophysiological techniques, such as patch clamping and electroencephalography (EEG), are commonly used to study the electrical signals generated by cells and tissues, allowing researchers to understand how these signals control various physiological processes. By studying the electrical activity of cells, researchers can gain insights into the functioning of the nervous system, muscle contractions, and communication between cells.
