Researchers at Howard Hughes Medical Institute are learning more about sleep using mice. Two types of mouse sleep mutations were studied: ‘Sleepy’ and ‘Dreamless.’ The Sleepy mice needed more sleep than normal mice - about one third more. They carried a mutation in the Sik3 kinase gene. The Dreamless mice did not show any rapid eye movement and carried a mutation in a sodium channel previously known to regulate neuronal excitability. Study author Masashi Yanagisawa said, ”Sleep need still remains a mystery, but what we hope is that this kinase is maybe the key, the initial key to this big door.”
