“…For example, female rats self-administer higher levels of cocaine, show greater escalation of cocaine intake over time, and have a more significant disruption of diurnal control over drug intake than males under extended-access cocaine self-administration conditions, which supports an enhanced vulnerability to transition from controlled to dysregulated cocaine use in females (Lynch andTaylor, 2004, 2005;Roth and Carroll, 2004;Smith et al, 2011;Kawa and Robinson, 2019;Algallal et al, 2020). Additionally, our more recent study showed that two addiction-like features, an enhanced motivation for cocaine and compulsive cocaine use despite negative consequences, developed sooner during withdrawal from extended-access cocaine self-administration in females compared to males (following 7 versus 14 days; Towers et al, 2021). Our previous study and work from others has also shown that these addiction-like features increase, rather than decrease, in magnitude over withdrawal (Gancarz-Kausch et al, 2014;Towers et al, 2021).…”

This incubation effect has been extensively described for cue-induced cocaine-craving, which increases progressively, or incubates, over protracted withdrawal in both humans and animals tested following extended-access drug self-administration (Grimm et al, 2001;Li et al, 2015).…”

“…In any case, this piece of data is yet another study reinforcing the particular vulnerability of administering cocaine in rats during this age window of adolescence (PND 33–39; García-Cabrerizo et al 2015 ) on increasing negative affect (García-Cabrerizo and García-Fuster 2019 ; Bis-Humbert et al 2021a ) and addictive-like responses (e.g., Parsegian et al 2016 ; García-Fuster et al 2017 ), but with the novelty of providing the impact for female rats. Thus, early-life stressed female rats exposed to adolescent cocaine showed enhanced negative affect in adulthood (during abstinence and drug re-exposure), highlighting the risk of early cocaine initiation for the progression toward cocaine addiction, in the context that negative reinforcement during abstinence could likely increase this vulnerability (e.g., Towers et al 2021 ).…”

“…Following acquisition, rats with ( n = 10) and without ( n = 9) a history of exercise were tested on motivation for fentanyl (0.25 µg/kg/infusion) using a PR schedule [ 42 ]. PR sessions began at approximately postnatal-day 53 and were conducted as described for acquisition testing except that the number of responses required to obtain an infusion increased throughout each session in the following steps: 1, 2, 4, 6, 9, 12, 15, 20, 25, 32, 40, 50, etc; ref.…”
