A simple method for implanting electrodes in freely moving neonatal rats.
A simple method for implanting cortical and subcortical electrodes in very young rats is described, which does not interfere with the behavior of the animal during the experiment. The cortical electrodes are anchored to the skull by a spiral whose first loop is introduced between the inner layer of the skull and the dura mater. The subcortical electrodes have a loop which rests above the skull. Both the spirals of the cortical electrodes and the loops of subcortical electrodes are then embedded in dental acrylic.
