Neuroscience: Glutamate neurons in the medial septum control wakefulness

Despite intensive research efforts, biologists still do not have a clear picture of the brain circuitry that controls behavioural arousal. However, new research has identified a novel septo-hypothalamic circuit that functions to promote wakefulness.
