A simple operation method was described for removing the olfactory bulbs of small rodents. The procedure was as follows : 1. Animals were anesthetized by intraperitoneal injection of pentobarbital sodium. 2. The hair of the head was clipped (Fig. 9) . 3. The scalp was cut along the midline between the eyes (Fig. 10) . 4. A hole was drilled in the skull overlying the olfactory bulbs (Fig. 14, 15) . 5. The olfactory bulbs were aspirated with a glass pipette (Fig. 18) . 6. After removing the bulbs by suction, the skin was closed by a single suture (Fig. 21) .
