encephalic (not comparable)
- of or relating to the encephalon
1891, Addison and Steele, The Spectator, Volume 2.:
- From men wholly without philosophy, who never looked heavenward, the more brutal land animals are derived, losing the round form of the cranium by the slackening and stopping of the rotations of the encephalic soul.
1905, Various, The Project Gutenberg Edition of "The French Immortals":
- The misfortune was that he could not find in himself any of the causes which resolve into insomnia; he had neither meningitis nor brain fever, nor anything that indicated a cerebral tumor; he was not anaemic; he ate well; he did not suffer with neuralgia, nor with any acute or chronic affection that generally accompanied the absence of sleep; he drank neither tea nor alcohol; and without this state of over-excitement of the encephalic centres, he might have said that he was in good health, a little thin, but that was all.
