Autism is one of the urgent problems in neuroscience. Early research in our laboratory found that dcf1 gene-deficient mice exhibited autistic behavior. Reviewing the literature, we know that the caudate putamen (CPu) brain region is closely related to the occurrence of autism. In this study, we observed that the electrical signal in the abnormal brain region of adult mice was enhanced by using field potential detection for the corresponding brain region. We then used retrovirus markers to track neurons in the CPu brain region and found that there are neural projections in the hippocampus-CPu brain region. Therefore, we selected DREADDs (Designer receptors exclusively activated by designer drugs) to inhibit the abnormal brain region of the mouse and found, through behavioral testing, that this can inhibit the autistic behavior of mice. This research provides new evidence for the understanding of the cause of autism and has accumulated new basis for the treatment of autism. It has theoretical significance and potential application value for the understanding and treatment of autism.
