Brain-like computing technology is generally divided into three levels: the structural level mimics the brain, the device level approaches the brain, and the intelligence level surpasses the brain. Among them, the structural level mimicking the brain refers to analyzing the brain as a physical and physiological object to obtain the basic unit (each Neurons and synapses, etc. ) and their connection relationships (network structure); device-level approximation to the brain refers to the development of devices that can simulate the functions of neurons and synapses, thereby limiting the physical space and power consumption Construct a human brain-scale neural network system; intelligence level beyond the brain refers to the information-like stimulation, training, and learning of brain-like computers to make them produce intelligence similar to that of the human brain. According to the above definitions, the following belong to the level of intelligence beyond the brain:. ['Draw accurate maps of the human brain to analyze and detect the brain.', 'Adjust the synaptic connection relationship, connection frequency and strength of the neural network.', 'Development of electronic equipment with a functional density equivalent to that of the human cerebral cortex.', 'Non-linear dynamics of capturing minute single neuron discharges.']
