Topic: Higuchi’s fractal dimension

Cognitive and motor functions of the human brain often display non-linear dynamics. Fractal dimension such as Higuchi’s fractal dimension (HFD) has been used as an effective method to probe these nonlinear dynamics and has been used to characterise different diseases. However, there is inconsistency in how HFD varies with age and disease in literature, which could be due to different computational techniques or frequency ranges used in these studies. To resolve this disparity, we investigated the frequency-dependant change of HFD with age for 64-channel electroencephalogram (EEG) data recorded
