Mapping transient hyperventilation induced alterations with estimates of the multi-scale dynamics of BOLD signal.

Mapping transient hyperventilation induced alterations with estimates of the multi-scale dynamics of BOLD signal.

Temporal blood oxygen level dependent (BOLD) contrast signals in functional MRI during rest may be characterized by power spectral distribution (PSD) trends of the form 1/f α. Trends with 1/f characteristics comprise fractal properties with repeating oscillation patterns in multiple time s...
