Membrane potential function as a battery, providing power to operate a variety of "molecular devices" embedded in the membrane. Second, in electrically excitable cells such as neurons and muscle cells, it is used for transmitting signals between different parts of a cell. Signals are generated by opening or closing of ion channels at one point in the membrane, producing a local change in the membrane potential. This change in the electric field can be quickly affected by either adjacent or more distant ion channels in the membrane. Those ion channels can then open or close as a result of the potential change,
General Data Format for Biomedical Signals BioSig library provides implementations for reading and writing of GDF in GNU Octave/MATLAB and C/C++. A lightweight C++ library called libGDF is also available and implements version 2 of the GDF format. General Data Format for Biomedical Signals The General Data Format for Biomedical Signals is a scientific and medical data file format. The aim of GDF is to combine and integrate the best features of all biosignal file formats into a single file format. The original GDF specification was introduced in 2005 as a new data format to overcome some of the limitations of the European Data Format for
