Furthermore, since both periods of phase shift/lock durations were found to be significantly shorter, that might contribute to an increased rate of phase reset, also seen in our data. Phase reset deregulation--phase locking periods being too brief and phase reset happening too often—appear to be consistent with the associated lower rate of information processing and reaction times found in the ME and CFS literature. These deregulated states represent the [[brain]] during nonoptimal functioning, rendering it inefficient for most types of information processing functioning, whether it is executive functioning, [[Memory problems|memory]], perceptual reasoning or information processing speed. When phase lock is significantly less than normal, as in this data set, the ability of the brain to sustain commitment of resources to mediate different functions is severely compromised. Phase shift duration in this data is also hypoactive, meaning that significantly less neurons are being recruited to perform a function than normal. The results here indicate slowed verbal comprehension, executive functions, perceptual reasoning, processing speed and memory, the sum total of which is known as [[cognitive impairment]].<ref name="Zinn2018" /></blockquote> [[File:CLROA-2-110-F1.gif|850px|thumb|center| Figure 1: Results of LORETA current source density in a case with CFS showing widespread decreased current density for delta at 2 Hz and beta (12- 15 Hz) demonstrating a global reduction in brain functioning (blue). The higher frequencies (beta) have been shown to be a function of delta frequencies. In other words, local oscillations are under constant influence of global brain dynamics (Buzsaki, 2006).<ref name="Zinn2018" />]] *2018, Cognitive Impairment in Fibromyalgia: A Meta-Analysis of Case–Control Studies<ref>{{Cite journal | title = Cognitive Impairment in Fibromyalgia: A Meta-Analysis of Case–Control Studies | url = https://journals.lww.com/psychosomaticmedicine/fulltext/2018/06000/cognitive_impairment_in_fibromyalgia__a.5.aspx | pmid = 29528888 | journal = Psychosomatic Medicine | volume = 80 | issue = 5 | pages = 432-438 | date = 2018 | last = Wu | first = Yu-Lin | last2 = Huang | first2 = Chun-Jen | last3 = Fang | first3 = Su-Chen | last4 = Ko | first4 = Ling-Hsin | last5 = Tsai | first5 = Pei-Shan }}</ref> - [https://journals.lww.com/psychosomaticmedicine/fulltext/2018/06000/cognitive_impairment_in_fibromyalgia__a.5.aspx (Abstract)]
