In laboratories where the brain's electrical language has long resisted systematic translation, a research team has built a platform capable of asking — and answering — a question that once seemed too vast to pose: which of our thousands of genes quietly govern the moment a neuron decides to fire? By silencing over 1,300 genes one at a time in human neurons and watching the electrical consequences unfold in real time, scientists have not only confirmed old intuitions but uncovered unexpected genetic actors linked to autism and Alzheimer's disease, suggesting that some of the most consequential
