Introduction Degradation in fractal motor activity regulation (FMAR), a measure of multiscale
self‐similarity of motor control, occurs in aging and accelerates with clinical progression to …

Background: Fractal motor activity regulation (FMAR), characterized by self-similar temporal
patterns in motor activity across timescales, is robust in healthy young humans but degrades …

Introduction Healthy physiological systems exhibit fractal regulation (FR), generating similar
fluctuation patterns in physiological outputs across different time scales. FR in motor activity …

Many outputs from healthy neurophysiological systems including motor activity display
nonrandom fluctuations with fractal scaling behavior as characterized by similar temporal …

Human motor activity has a robust, intrinsic fractal structure with similar patterns from
minutes to hours. The fractal activity patterns appear to be physiologically important because …

Introduction Many physiological signals yield fractal characteristics, ie, finer details at higher
magnifications resemble details of the whole. Evidence has been accumulating that such …

Prior studies have reported increased cortical excitability in people with Alzheimer's disease
(AD), but findings have been inconsistent, and how excitability relates to dementia severity …

Brain activity is complex; a reflection of its structural and functional organization. Among
other measures of complexity, the fractal dimension is emerging as being sensitive to …

Nonlinear analyses of actigraphy data were utilized to investigate circadian rest-activity
system motor control in nursing-home residents with dementia and with/without aggressive …

Background Higuchi's fractal dimension (FD) captures brain dynamics complexity and may
be a promising method to analyze resting‐state functional magnetic resonance imaging …
