Acetylcholinesterase staining can be used to subdivide the lateral posterior nucleus in newborn kittens.

Acetylcholinesterase staining and double labeling techniques were used to study the subdivision of the lateral posterior nucleus (LP) of the thalamus in newborn kittens. The LP was divided into acetylcholinesterase-positive and -negative parts, which densely project onto the lateral and medial banks of the lateral suprasylvian area, respectively. These results mean that acetylcholinesterase staining can be used to subdivide the LP in newborn kittens.
