The distributive pattern of beta-galactosidase in the forebrain and mid-brain of the mouse

The present study demonstrates the distribution pattern of beta-galactosidase (BGL) in the forebrain and mid-brain of the mouse. Mild enzyme activity was observed in the neurons of the forebrain and mid-brain. Interestingly, strong enzyme activity in some nuclei was due to the presence of myelinated fibers. Most of the fiber tracts and commissures showed strong enzyme activity. The involvement of BGL in myelin metabolism is discussed.
