What Is GABA? How Does It Affect Hypersomnia? A New Video Series Explains!

Amanda Freeman, PhD

What is GABAA? And how does it affect hypersomnia? We are very pleased to present a two-part video series by neuroscientist Amanda Freeman, PhD, of Emory University, which describes, in layman’s terms, exactly how y-aminobutyric acid, better known as GABA, affects sleep. Dr. Freeman explains that although there are 5 wake-promoting transmitters in your brain, there is only one neurotransmitter that promotes sleep – and that is GABA. Research performed at Emory University by Dr. David Rye and his colleagues has suggested the possibility that, with respect to GABA-related hypersomnia, the problems with wakefulness may be due more to excessive activity of the GABA system (thereby inhibiting the wake-promoting transmitters of your brain), rather than to a defect in the brain’s wake-promoting transmitters themselves. As Dr. Freeman notes, this was a paradigm shift in the thinking about sleep and GABA.

The first part of this two-part video series focuses on explaining what GABA is and what role it plays in our sleep. The second part of this two-part video series focuses on how GABA inhibits neurons, and how research by Dr. Rye and his colleagues at Emory have identified an endogenous molecule in the cerebrospinal fluids of patients with hypersomnia that increases the activity of GABA receptors.
