Fractality in the neuron axonal topography of the human brain based on 3-D diffusion MRI

摘要: In this work the fractal architecture of neuron axonal topography human brain is evaluated, as derived from 3-D diffusion MRI (dMRI) acquisitions. This a 3D extension performed previously in 2D regions interest (ROIs), where dimension was computed dMRI data. A group study with 18 subjects here conducted and dimensions Df entire volume brains estimated via box counting, correlation mass methods. The axon data obtained using tractography algorithms on tensor imaging brain. We find that all three calculations give consistent results across subjects, namely, they demonstrate characteristics short medium length scales: different exponents prevail at scales, an indication multifractality. surmise complexity stems collective property emerging when many local units, performing functional tasks having topologies, are recorded together.
