Infant grasp learning: a computational model.

abstract：:Experimental neurogenic tumors were induced transplacentally in rats by single injections of ethylnitrosourea (ENU). The resulting primary tumors as well as isogenic transplantation tumor lines and clonal cell lines derived therefrom were examined for their content of the brain specific protein 14-3-2 by a quantitativ...
