Spectral analysis of calcium oscillations.

Calcium (Ca2+) oscillations are universal signals exploited by cells to regulate a vast number of cellular processes. Frequency and amplitude, the key features of oscillating waves, can yield information that can be decoded by intracellular processes. Analysis and quantification of Ca2+ oscillations are crucial for understanding the general concept of Ca2+ signaling. This protocol presents a method for performing spectral analysis of Ca2+ oscillations using MATLAB software.
