Nonanesthetics can suppress learning. Desflurane and the nonimmobilizer 1,2-dichlorohexafluorocyclobutane suppress learning by a mechanism independent of the level of unconditioned stimulation. Eger EI, II, Koblin DD, Harris A, et al. Inhaled anesthetics produce immobility and amnesia by different mechanisms at different sites. Eger EI, II, Halsey MJ, Harris RA, et al.
Volatile anesthetics produce immobility by acting on two sites approximately five carbons apart.
