A widely held dogma in the preclinical addiction field is that females are more vulnerable than males to drug craving and relapse. Here, we first review clinical studies on sex differences psychostimulant opioid Next, reinstatement of seeking after extinction self-administration, incubation (time-dependent increase during abstinence). We also discuss ovarian hormones' role relapse humans animal models speculate brain mechanisms underlying their cocaine rodent models. Finally, imaging responses cues stress men women.The results reviewed do not appear support notion women However, this conclusion tentative because most were correlational, sufficiently powered, a priori designed detect differences. Additionally, suggest stress. The provide evidence for stress-induced but cue- or cocaine-induced seeking. These modulated part by hormones. In contrast, available data relapse/reinstatement methamphetamine opioids

Drugs of abuse are thought to promote addiction in part by “hijacking” brain reward systems, but the underlying mechanisms remain undefined. Using whole-brain FOS mapping and vivo single-neuron calcium imaging, we found that drugs augment dopaminoceptive ensemble activity nucleus accumbens (NAc) disorganize overlapping responses natural rewards a cell type–specific manner. Combining FOS-Seq, CRISPR-perturbation, single-nucleus RNA sequencing, identified Rheb as molecular substrate regulates signal transduction NAc while enabling suppress consumption. Mapping NAc-projecting regions activated revealed input-specific effects on These findings characterize dynamic, circuit basis common pathway, wherein interfere with fulfillment innate needs.

Background Studies using continuous-access drug self-administration showed that cocaine seeking increases during abstinence (incubation of craving). Recently, studies intermittent-access increased motivation to self-administer and seek cocaine. We examined whether intermittent would potentiate incubation craving in male female rats the estrous cycle's role this incubation. Methods In experiment 1, self-administered either continuously (8 hours/day) or intermittently (5 minutes ON, 25 OFF × 16) for 12 days, followed by relapse tests after 2 29 days. experiments 3, six, 12, 18 sessions. 4, 3 cycle was measured a vaginal smear test. Results Incubation observed both sexes continuous self-administration. Independent access condition day, higher than rats. sexes, on days access. rats, significantly estrus non-estrus; access, effect independent training duration. Conclusions caused time-independent abstinence. time-dependent increase (incubation) is critically dependent phase.

Our environment and economy are at a crossroads. This paper attempts cohesive narrative on how human evolved behavior, money, energy, the fit together. Humans strive for same emotional state of our successful ancestors. In resource rich environment, we coordinate in groups, corporations nations, to maximize financial surplus, tethered carbon. At global scales, emergent result this combination is mindless, energy hungry, CO2 emitting Superorganism. Under dynamic now behaviorally ‘growth constrained’ will use any means possible avoid facing reality.

We recently developed a mouse model of appetitive operant aggression and reported that adult male outbred CD-1 mice lever-press for the opportunity to attack subordinate relapse seeking during abstinence. Here we studied role nucleus accumbens (NAc) dopamine receptor (Drd)1- Drd2-expressing neurons in self-administration seeking. trained self-administer intruders (9 d, 12 trials/d) tested them on abstinence Day 1. used immunohistochemistry in situ hybridization measure neuronal activity marker Fos NAc, cell-type-specific colocalization with Drd1- neurons. To test causal neurons, validated transgenic hybrid breeding strategy crossing inbred Drd1-Cre Drd2-Cre Cre-DREADD (hM4Di) inhibit NAc neuron activity. found induced higher expression shell than core, Fos colocalized Drd1 Drd2 both subregions, chemogenetic inhibition Drd1-, but not Drd2-, expressing decreased Results indicate Drd1-expressing is critical Our study also validates simple between C57-based Cre lines can be cell-type circuit mechanisms reward relapse. SIGNIFICANCE STATEMENT Aggression often comorbid neuropsychiatric diseases, including drug addiction. One form, aggression, exhibits symptomatology mimics addiction hypothesized due dysregulation addiction-related circuits. However, our mechanistic understanding circuitry modulating limited. novel relapse, combination immunohistochemistry, hybridization, manipulations examine how cell types are recruited for, control, one population, 1-expressing act as modulator
