Summary

This chapter focuses on neuroimaging studies investigating the effects of benzodiazepines (BDZ) and z-drugs on regional glucose metabolism and brain perfusion as measured with 15O-water (H215O)-position emission tomography (PET) and blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) in wakefulness and non-rapid eye movement (NREM) sleep. The clinical effects of ligands at BDZ binding sites not only consist of sedation and sleep induction, but also include anxiolysis, seizure suppression, and muscle relaxation. The effects of pharmacological agents on regional brain activity during sleep can be investigated by employing neuroimaging and polysomnography simultaneously. Imaging findings support the concept that persistent activity in distinct arousal networks, particularly continuous activation of the precuneus, is linked to impaired sleep quality in patients with insomnia. With regards to pharmacological interventions, sedative-hypnotics may provide an antidote to the proposed central nervous system (CNS) hyperarousal seen in these patients during sleep.
