Abstract:
This study investigated the roles of hypnotizability and hypnosis in suggested emotional numbing. Thirty-two high hypnotizable and 32 low hypnotizable participants were administered either a hypnotic or wake induction and were then presented with emotionally distressing and neutral images during a suggestion for emotional numbing or a control condition. Emotional response was indexed through self-report and EMG corrugator-muscle activity. High hypnotizable participants, in both the hypnosis and wake conditions, reported more diminished emotional responses on self-report and EMG corrugator-muscle activity than low hypnotizable participants during the emotional-numbing suggestion. These findings suggest that elevated hypnotic susceptibility, rather than hypnosis, is an important mediator of emotional numbing. The importance of individual differences in emotional numbing is discussed.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
