Polypeptides of cerebral subcellular fractions of differentially-housed mice

Summary The difference in protein of cerebral nerve-ending fractions caused by differential housing of male mice is of a quantitative nature and might reflect a change in the number of nerve-endings.This work was supported in part by Centro Nacional Ramón y Cajal (de la Seguridad Social) and Fundación Juan March and was conducted in part at the Istituto Nazionale per lo Studio e la Cura dei Tumori, Milan Italy, while Dr F. P. Conde was on a research fellowship. Thanks are due to Mr Riccardo Gelati for technical assistance and to Mr Mario Azzini for the photography.
