“…Of significance to the Carter study (13) is the finding that high EEG coherence is a predictor of superior cognitive processing, in agreement with studies on TM (40,41). It presents a link between (i) the observed effects of meditation practice on brain function, (ii) increased brain processing capacity, (iii) improvements in cognitive function, and (iv) a characteristic of brain function in higher states of consciousness.…”

This article is the first of two comparing findings of studies of advanced practitioners of Tibetan Buddhist meditation in remote regions of the Himalayas, with established results on long-term practitioners of the Transcendental Meditation programs. Many parallel levels of improvement were found, in sensory acuity, perceptual style and cognitive function, indicating stabilization of aspects of attentional awareness. Together with observed increases in EEG coherence and aspects of brain function, such changes are consistent with growth towards a state of total brain functioning, i.e. development of full mental potential. They are usually accompanied by improved health parameters. How they may be seen to be consistent with growth of enlightenment will be the subject of a second article.

“…However, they reported somewhat heterogeneous findings that did not seem to have inspired their authors to continue their work on these topics. Therefore, only single studies were reported, which sometimes suffered from methodological problems and were not continued or extended (Beaumont, Mayes, & Rugg, 1978;Sheppard & Boyer, 1990;Tucker, Dawson, Roth, & Penland, 1985). Other studies on EEG coherence and word processing dealt with word category differences and are addressed in the following sections.…”

The contribution of EEG coherence to the investigation of language

The contribution of EEG coherence analysis to the investigation of cognition and, in particular, language processing is demonstrated with examples of recent EEG studies. The concept of EEG coherence analysis is explained, and its importance emphasized in the light of recent neurobiological findings on frequency-dependent synchrony as a code of information processing between nerve cell assemblies. Furthermore, EEG coherence studies on naturally spoken and written word and sentence processing are reviewed and experimental results are presented giving new insights into the occurrence of ''transient functional language centers'' within the brain.

“…Although a number of researchers have employed coherence analysis to examine functional communication in the cortex during verbal tasks (Razoumnikova, 2000;Sheppard & Boyer, 1990;Volf & Razumnikova, 1999) and various other cognitive and creative tasks (Petsche, 1996;Petsche, Kaplan, von Stein, & Filz, 1997), we are aware of no published reports of the interaction between cognitive and motor areas during the execution of psychomotor skill in individuals who are highly skilled.…”

Electroencephalographic (EEG) coherence was assessed during a 4-s aiming period prior to trigger pull in expert marksmen (n = 10) and skilled shooters (n = 9) over the course of a regulation round of small-bore rifle shooting. Although both groups were highly experienced, the skilled group had lower ability. Given that specialization of cortical function occurs as domain-specific expertise increases, experts were predicted to exhibit less cortico-cortical communication, especially between cognitive and motor areas, compared to the skilled group. Coherence was assessed for three frequency bands (low alpha, 8–10 Hz; high alpha, 10–13 Hz; and low beta, 13–22 Hz) using sites F3, Fz, F4, C3, Cz, C4, T3, T4, P3, Pz, P4, O1, and O2. Compared to the skilled group, experts exhibited lower coherence between left temporal (T3) and mid-line frontal (Fz) regions for low-alpha and low-beta frequencies, lower coherence for high-alpha between all left hemisphere sites and (Fz), and lower coherence between T3 and all midline sites for the low-beta band. The results reveal that, compared to lesser skilled shooters, experts engage in less cortico-cortical communication, particularly between left temporal association and motor control regions, which implies decreased involvement of cognition with motor processes.
