Along with the flourishing of brain-computer interface technology,the brain-to-brain information transmission between different organisms has received high attention in recent years.However,specific information transmission mode and implementation technology need to be further studied.In this paper,we constructed a brain-to-brain information transmis-sion system between pigeons based on the neural information decoding and electrical stimulation encoding technologies.Our system consists of three parts:(1)the"perception pigeon"learns to distinguish different visual stimuli with two discrepant frequencies,(2)the computer decodes the stimuli based on the neural signals recorded from the"perception pigeon"through a frequency identification algorithm(neural information decoding)and encodes them into different kinds of electrical pulses,(3)the"action pigeon"receives the Intracortical Microstimulation(ICMS)and executes correspond-ing key-pecking actions through discriminative learning(electrical stimulation encoding).The experimental results show that our brain-to-brain system achieves information transmission from perception to action between two pigeons with the average accuracy of about 72％.Our study verifies the feasibility of information transmission between inter-brain based on neural information decoding and ICMS encoding,providing important technical methods and experimental program references for the development of brain-to-brain communication technology.
