Credit: Neuron (2025). DOI: 10.1016/j.neuron.2025.05.001 Research teams have created a versatile set of gene delivery systems that can reach different neural cell types in the human brain and spinal cord with exceptional accuracy. These delivery systems are a significant step toward future precise gene therapy for the brain that could safely control errant brain activity with high precision. In contrast, current therapies for brain disorders mostly treat o
