Neural excitement (IMAGE) Virginia Tech Caption Researchers at the Fralin Biomedical Research Institute are exploring how gene variants affect brain cells in children with severe epilepsy. Here, the scientists use green and red fluorescent proteins to identify different types of neurons in a mouse model expressing a mutated KCNT1 gene – a gene associated with seizures in children. Cells expressing the green color are excitatory and may be involved with seizure activity.
