“…Other complex and nonlinear temporal properties are also present in basal ganglia spike trains from rodents, primates and patients with movement disorders (Li, Jia et al 2008, Lim, Sanghera et al 2010, Hohlefeld, Huebl et al 2012, Darbin, Adams et al 2013, Hohlefeld, Ehlen et al 2015. The most popular nonlinear measure for the characterization of parkinsonian spike trains is probably entropy, which diminishes due to pharmacological or stimulation treatment, and increases due to alertness (Latora 2000, Lafreniere-Roula, Darbin et al 2010, Lim, Sanghera et al 2010, Alam, Sanghera et al 2015, Darbin, Jin et al 2015. Importantly, entropy can be estimated wrongly if the multifractality of a system is not considered (Costa, Lyra et al 1997, Lyra 1998, Latora 2000.…”
