Problems solved by technology

However, due to the relatively fixed brain structure network, the structural network prediction model constructed has defects. After testing, it is found that the model prediction data is too different from the actual data to be popularized and utilized in practical applications, thus failing to provide accurate human intelligence for brain-inspired artificial intelligence. The brain function simulation model is not conducive to the intelligent development of artificial intelligence, and at the same time, it cannot provide accurate data support for the judgment of human brain diseases through the model

Abstract

The invention provides a virtual digital brain construction method and system and an intelligent robot control system. The virtual digital brain construction method comprises the following steps of: constructing a virtual digital brain to obtain a brain function causal connection network in a resting state and a task state; constructing a brain structure network by using a hybrid fiber bundle tracking method combining a deterministic algorithm and a probabilistic algorithm; comparing the structure network with the brain function causal connection network, and deleting causal connection withoutdirect structure connection in the brain interval to obtain an improved virtual digital brain; and taking the resting state as a base line, acquiring an activation state of a brain region under tasksignal stimulation, and establishing a node neural activity signal prediction model, namely a final virtual digital brain. According to the invention, the brain function causal connection network is improved through the structure network, and the causal connection without direct structure connection in the brain interval is deleted and the influence of indirect connection is removed by jointly using the function and structure information, so that the establishment of a more effective node neural activity signal prediction model in subsequent processing is facilitated.
