Thia study revealed a role of the BNST GABAergic system in sleep/wakefulness control, especially in shifting animals' behavioral states from NREM sleep to wakefulness.

To test that idea, they examined brain activity during NREM sleep in rats trained to locate rewards in a maze and in rats that explored the maze in a random fashion.

A group of researchers led by Takeshi Sakurai, Vice Director of the International Institute for Integrative Sleep Medicine (WPI-IIIS), University of Tsukuba, found that acute optogenetic excitation of GABAergic neurons in BNST during non-rapid eye movement (NREM) sleep in mice resulted in immediate transition to a wakefulness state without the function of orexins, highly important neuropeptides for maintaining wakefulness.

Using a cutting-edge NeuroGrid system they invented, along with recording electrodes placed deeper into the brain, the researchers examined activity in several parts of rats’ brains during non-rapid eye movement (NREM) sleep, the longest stage of sleep.
