“…Lower values of coherence are associated with white matter lesions and decreased cerebral blood flow (Leuchter, Cook, Uijtdeharge, Dunkin, Lufkin, Anderson-Hanley, Abrams, Rosenberg-Thompson, O'Hara, Simon, Osato, & Babaie, 1997), schizophrenia (Wada, Nanbu, Kikuchi, Koshino, Hashimoto, & Yamaguchi, 1998), depression (Leuchter et al, 1997), and normal aging (Koyama, Hirasawa, Okubo, & Karasawa, 1997). Higher values of coherence have been interpreted as evidence for functional coupling (Thatcher, Krause, & Hrybyk, 1986), information exchange (Petsche et al, 1988), or functional coordination (Gevins, Bessler, Morgan, Cutillo, White, Greer, & Illes, 1989) between brain regions. Higher beta coherence correlates with inhibition processes in Go/No Go tasks (Shibata et al, 1997) and in self-paced finger movements (Leocani, Toro, Manganotti, Zhuang, & Hallett, 1997).…”

“…1). Higher slow alpha coherence has been interpreted as evidence for functional coupling [18], information exchange [19], or functional coordination [20] among brain regions. It was reported that the slow alpha band (8-10 Hz) reflects nontask-related cognitive processes such as attention and expectancy, whereas the fast alpha band (10-12 Hz) reflects task-related processes [21].…”

“…Functional techniques based on the correlational analysis of electroencephalographic (Gevins et al, 1979(Gevins et al, , 1981(Gevins et al, , 1989Thatcher et al, 1986;Tucker et al, 1986) or cerebral blood flow (CBF; Alexander and Moeler, 1984;Friston, 1994;McIntosh and Gonzalez-Lima, 1994;Strother et al, 1995;Friston et al, 1996;Paus et al, 1996) data are indirect and may not show actual neural connectivity. The correlational studies suffer a major limitation in that the engagement of a subject in performing a task confounds the data being acquired: the observed "coactivations" may reflect relationships between different components of behavior rather than connectivity.…”
