Time-of-day as a critical biological variable
2021, Neuroscience and Biobehavioral ReviewsCitation Excerpt :Drug-seeking behaviors are influenced by circadian rhythms (Falcón and McClung, 2009; McClung, 2007; Webb, 2017). Time-of-day can influence drug-seeking behavior and behavioral sensitization to drugs in rodents (Arvanitogiannis et al., 2000; Sleipness et al., 2007); drug sensitization is influenced by the circadian system (Abarca et al., 2002; Baird and Gauvin, 2000; Sleipness et al., 2005) and drugs of abuse can also feedback to modulate circadian rhythms (Kosobud et al., 1998; Uz et al., 2005). For example, using locomotor output as a behavioral measure of cocaine sensitization, time-of-day influences sensitization.
Circadian entrainment by food and drugs of abuse
2019, Behavioural ProcessesCitation Excerpt :The experiments designed to test this hypothesis all used female Wistar rats, were run in constant dim light to eliminate time of day cues, and used rate-limited feeding (consumption limited to no more than two 97 mg pellets/5 min) to prevent meal entrainment that might have arisen secondary to drug effects on feeding and wheel running. We first demonstrated that MA injections given at 24 h intervals entrained anticipatory wheel running, and that a transient elevation in wheel running recurred 24 h after the final injection (Kosobud et al., 1998). MA injections given at 31 h intervals were followed 24 h later by wheel running, similar to circadian ensuing activity observed after 31 h meal delivery in intact (Pecoraro et al., 2000) and SCN-lesioned rats (Kosobud et al., 2007).
Racing the clock: The role of circadian rhythmicity in addiction across the lifespan
2018, Pharmacology and TherapeuticsReversal of the sleep–wake cycle by heroin self-administration in rats
2016, Brain Research BulletinCitation Excerpt :In humans, there is evidence of increased wakefulness, decreased NREM sleep, and decreased REM sleep in the first 5–7 days of heroin withdrawal (Howe et al., 1980a,b,c). Even among studies examining drug effects on sleep, little attention has been given to the effects of drug taking and abstinence on circadian rhythm in addicts, despite evidence that drugs of abuse can entrain activity (Gillman et al., 2009; Honma et al., 1987; Kosobud et al., 1998; White et al., 2000). Recently, circadian effects of drugs has been gaining traction as a topic of interest (Hasler et al., 2012).
Circadian clock genes: Effects on dopamine, reward and addiction
2015, AlcoholCitation Excerpt :Additionally, the circadian regulation of dopamine transmission and signaling plays a role in reward (Kosobud et al., 2007). For example, daily methamphetamine injections have been shown to entrain animals and induce anticipatory locomotor activity to the time of injection (Kosobud, Pecoraro, Rebec, & Timberlake, 1998). Ethanol, cocaine, and nicotine have also been shown to induce this anticipatory behavior and alter behavioral rhythms (Gillman, Kosobud, & Timberlake, 2008; Kosobud et al., 2007; White, Feldon, Heidbreder, & White, 2000).
