▶ Development of data-drive methods for brain mapping. ▶ Wavelet correlations as alternatives to conventional GLM analysis. ▶ Wavelet correlations show greater sensitivity compared to GLM. Functional magnetic resonance imaging (fMRI) based on BOLD signal has been used to indirectly measure the local...
