Webneurons heavily innervate brain regions involved in the control of wakefulness, appetite, thermoregulation and autonomic control [3,4], and orexins have excitatory effects on post-synaptic neurons [2,5] (Figure1). Orexin neurons are predominantly active during wakefulness [6], and injec-tion of orexin-A into the lateral ventricles increases wake- WebWakefulness, which is indispensable for survival, is thus ensured by a whole network of redundant structures.
