The study of brain-to-brain information transmission between different organisms has attracted great attention in recent years,but the specific experimental paradigm and the way of information transfer still need to be further studied.In this paper,pigeons were used as model animals and the optic tectum(OT)related to visual perception was used as the target brain area.Combined with the experimental paradigm of steady state visual evoked potential(SSVEP),the experimental paradigm based on the neural information decoding and encoding was designed by using microstimulation as the way of pigeon brain-to-brain information transmission.And then the brain-to-brain information transmission experiment system of pigeons was built,which can realize that transferring the visual information perceived by the “perceived pigeon” to the “behavior pigeon”,stimulating the “behavior pigeon” to complete the desired behavioral response,and verifying the feasibility of brain-to-brain information transmission on the basis of microstimulation.The work done is summarized as follows:(1)Designed the pigeon brain-to-brain information transfer experiment paradigm and built the brain-to-brain information transfer system.Firstly,combined with the SSVEP experimental paradigm,an experimental paradigm that can transmit perceptual information between the brains of two pigeons was designed by using microstimulation as a way of brain-to-brain information transmission.According to this experimental paradigm,a brain-to-brain information transmission system that could meet the requirements was constructed.In this system,neural signals of “perceived pigeon” can be collected in real time,processed online,and converted into corresponding electrical stimulation instructions that were transmitted to “behavior pigeon”.(2)The SSVEP coding method for different visual information that can be stably and effectively distinguished by “Perceived Pigeon” is determined.The study on the SSVEP response characteristics of the “perceived pigeon” under different frequency visual stimuli and the stability of the SSVEP signal that detected at different stimulation frequencies determined the specific frequency of visual stimuli with high stability suitable for brain-to-brain information transfer experiments.(3)The electrical stimulation coding mode that can be effectively distinguished by “behavior pigeon” is determined.Combined with the behavioral performance of the pigeons,the experiment to distinguish different frequency electrical stimulation modes by "behavior pigeons" was carried out.The experiment was proved that the pigeons can clearly distinguish both high and low frequency electrical stimulation modes,and verified that the feasibility of using microstimulation to transfer effective information transmission to the brain of “behavior pigeon”.(4)Completed the verification of brain-to-brain information transfer experiment in two pigeons.In the experiment,the “perceived pigeon” perceives two different frequencies of visual stimulus information,and transmits the visual information to the “behavior pigeon” brain by microstimulation.The “behavior pigeon” can make corresponding behavioral responses according to the electrical stimulation mode.The experiment realized the transmission of visual information between the brains of two pigeons,and verified the feasibility of information transmission between brains based on microstimulation.
