I våken tilstand skvetter vi til når orienteringsaktivering følges av akutt noradrenerg fyring. I REM søvn er noradrenerge celler i locus coeruleus aktivt inhibert og fyrer ikke. Dopaminerge celler i substantia nigra/ventrale tegmentum fyrer innenfor gammaspekteret både i REM og våken tilstand. Den særegne balansen mellom noradrenerg og dopaminerg aktivitet i REM kan være forklaringen på hvorfor vi ikke "skvetter" i søvne og ved drømme-orientering.

Alzheimer's Disease: New Study Reveals Locus Coeruleus As First Brain Structure Affected By Disease

Researchers pinpoint brain region as ‘ground zero’ of Alzheimer’s disease The locus coeruleus is a small part of the brainstem that releases the neurotransmitter responsible for regulating heart rate, attention, memory and cognition.
