　　Objective The olfactory system is important for mammals.It plays a critical role in the recognition of conspecifics,predators and prey.Taking advantage of this sensitivity in sense of scent,researchers use behavior-analytic strategies to teach dogs and some rodents to detect explosives,drugs,and even the presence of TB in human sputum samples.These animal detectors are efficient with a high rate of hits.However,this discrimination training has so far been conducted manually,and may take a few months to meet the criterion.The present study is to apply brain-machine interfaces in olfactory information decoding on rats olfactory bulb in vivo for odor-detective rat-robot development.Methods An odor-specific maps was first obtained by intrinsic optical imaging,and then the multi-electrode array was implanted into the specified area of the olfactory bulb for neural signal acquirement.The performance of the odor information decoding was estimated to determine the stability of the system.Results(1)Odorant stimulation evokes intrinsic signal activities in the rat olfactory bulb.(2)Electrode array implantation under the guide of the odor map.(3)Neural activity shows stability in odor information decoding.Conclusion This study shows the possibility of an olfaction-assisted rat-robot system.
