Differentiating resting brain states using ordinal symbolic analysis
(Institute of Physics (IOP), 2018-10-08)
Article
Accés obertSymbolic methods of analysis are valuable tools for investigating complex time-dependent signals. In particular, the ordinal method defines sequences of symbols according to the ordering in which values appear in a time ... -
Entropy measures as descriptors to identify apneas in rheoencephalographic signals
(2019-06-18)
Article
Accés obertRheoencephalography (REG) is a simple and inexpensive technique that intends to monitor cerebral blood flow (CBF), but its ability to reflect CBF changes has not been extensively proved. Based on the hypothesis that ... -
