BUTIFtoolbox is used to extract transient oscillatory dynamics from signals. Until now, it was succesfully applied to LFP (Local Field Potentials) and EEG (Electroencephalographic) signals. Applications to other fields could be researched.

“Wavelets are mathematical functions that cut up data into different frequency components, and then study each component with a resolution matched to its scale. They have advantages over traditional Fourier methods in analyzing physical situations where the signal contains discontinuities and sharp spikes.”
