Module 6: Figure encoding oscillatory information
Different modes of information encoding Ca2+ oscillations.
There appear to be three main mechanisms for encoding information:
- Frequency modulation (FM). One of the important features of many Ca2+ oscillations is that frequency varies with agonist concentration, indicating that cells may employ FM as a mechanism for encoding information.
- Amplitude modulation (AM). Another way of encoding information is to vary the amplitude of the Ca2+ transients.
- Shape modulation. Information may also be included in the width of the individual transients.
