The power of electrophysiologically measured cortical activity decays with an approximately 1 /fX function. The slope of this decay (i.e. the spectral exponent, X) is modulated by various factors such as age, cognitive states or psychiatric/neurological disorders. Interestingly, a mostly parallel line of research has also uncovered similar effects for the spectral slope in the electrocardiogram (ECG). This raises the question of whether these bodywide changes in spectral slopes are (in-)depen...
