as well as information processing, storage, and retrieval, whereas dysregulation of this fine-tuned balance between chaotic and non-chaotic brain dynamics can lead to breakdown of behavior observed in psychopathology (Birbaumer et al., 1995; Elbert et al., 1994; Kitzbichler et al., 2009; Lutzenberger et al., 1995). A twin study using a pointwise dimension (PD2) measure showed that EEG complexity is highly heritable (65%) in the resting eyes closed condition, with somewhat lower heritability (about 50%) in the eyes open condition, suggesting that this complexity measure is a useful indicator of genetically transmitted characteristics of cortical dynamics (Anokhin et al., 2006b).
