Many animals are known to sleep in some form or another. The brain activities during sleep such as slow-wave (SW) or rapid-eye movement (REM) had, however, only been seen in birds and mammals, suggesting that perhaps only they have brains that sleep the way humans think of it. Enter Mark Shein-Idelson and colleagues at the Max Planck Institut in Frankfurt, Germany, who report that a lizard – the Australian dragon Pogona vitticeps – shows SW and REM over 6 to 8 h with a period of about 80 s. Apparently lizards sleep much like we do.
