Chrm1 and Chrm3


Genes that Regulate How Much We Dream

Acetylcholine receptors Chrm1 and Chrm3 (illustrated as Sandman gnomes 1 and 3) are essential for REM (dream) sleep. In this visual description of the study, the receptors help a mouse dream about a sleeping cat and Michel Jouvet (1925-2017), a pioneer of REM sleep studies.

A new study identifies two genes which regulate how much we dream. The genes, Chrm1 and Chrm3, play a key role in regulating REM sleep and function in different ways.
