title: Acetylcholinesterase reappearance in the early reparative process in the optic tectum of newt. An electron microscopic study.
abstract: AChE distribution during the early phases of the repairing process following the removal of a plug from the optic tectum of newt has been investigated. The first AChE-positive neurons appear in the regenerating area on the 60th day after the operation. At this stage acetylcholinesterase activity is clearly seen also between the nervous fibers and in some large dendrites, present in the superficial fibrous area. The enzyme distribution and the submicroscopic organization show that in this area cholinergic connections between regenerated axons and newly-formed nervous elements are being established.
