Abstract:

The neural responses of Gekko gecko olfactory bulb to amyl acetate were examined by extracellular recording techniques.Responses of 275 neurons in 21 geckoes could be classified into 3 categories,no response (43.6%),suppression (4.7%),and excitation (51.7%).The excited neurons could be further classified into 4 subtypes by temporal patterns,long term excitation (34.5%),short term excitation (6.25%),delayed response (6.25%) and neurons excited when cancelling stimulation (4.7%).The neural responses elicited by amyl acetate could be found generally at the dorsal side of rostral part and the ventral side of caudal part in olfactory bulbs.The results provide basic information on locomotion modulation by stimulating the animal’s olfactory neural system.
