The main research topics in the Meerlo lab are: 1) comparative studies on the regulation and function of sleep in different species; 2) sleep as a recovery process that supports neuronal plasticity and brain function, including memory formation; and 3) the neurobiological and neuroendocrine consequences of chronically disrupted or restricted sleep, with special emphasis on systems that are involved in stress and have been implicated in mood disorders and cognitive disturbances.
