Two fetus-specific globulins, al and a2·fetoglobulins, were detected in rat fetal serum, and the former was detected in amniotic fluid, using respective monospecific rabbit immune sera. Immunochemical distinction of these two proteins was demonstrated. By polyacrylamide gel disc electrophoresis, al-fetoglobulin was further resolved into fast and slow migrating subcomponents having a similar rea...

This study investigated the capacity of the E20 rat fetus to adaptively alter patterns of interlimb coordination in a prenatal model of motor learning. Fetal limb movement was manipulated with an interlimb yoke, consisting of a fine thread attached at the ankles, which created a physical linkage between two limbs. Exposure to the yoke resulted in a gradual increase in conjugate movements of the...
