[0002] The olfactory bulb is a part of the telencephalic cortex, located below and at the front end of the olfactory groove on the orbital surface of the frontal lobe of the cerebral hemisphere. It is flat and oval in shape, and migrates backward to the olfactory tract. The olfactory nerve composed of the central processes of the bipolar cells of the olfactory mucosa enters the underside of the frontal lobe through the holes of the cribriform plate, and most of the fibers end at the front end of the olfactory bulb. Therefore, the olfactory bulb can be regarded as the terminal nucleus of the olfactory nerve and is the primary center of olfaction. Damage to the olfactory bulb may lead to anosmia, and the reasons include head trauma, aging and other reasons. The utility model product is used in conjunction with electrophysiological detection equipment to collect biological signals from the olfactory bulb of the mouse brain. Utility Model Content
