This tradeoff is known as the explore-exploit dilemma. To better understand the neural mechanisms underlying how humans and animals address the explore-exploit dilemma, a good animal behavioral model is critical. Most previous rodents explore-exploit studies used ethologically unrealistic operant boxes and reversal learning paradigms in which the decision to abandon a bad option is confounded by the need for exploring a novel option for information collection, making it difficult to separate different drives and heuristics for exploration. In this study, we investigated how rodents make explore-exploit decisions using a spatial navigation horizon task (Wilson et al., 2014) adapted to rats to address the above limitations. We compared the rats' performance to that of humans using identical measures. We showed that rats use prior information to effectively guide exploration. In addition, rats use information-driven directed exploration like humans, but the extent to which they explore has the opposite dependance on time horizon than humans. Moreover, we found that free choices and guided choices have different influences on exploration in rodents, a finding that has not yet been tested in humans. This study reveals that the explore-exploit spatial behavior of rats is more complex than previously thought.

Serotonergic activity within the amygdala influences both anxiety-like behavior and aversive memory consolidation. To evaluate the effects of serotoninergic manipulations within the basolateral amygdala (BLA) on anxiety-like behavior and aversive memory in rats tested in the plus-maze discriminative avoidance task (PMDAT). The PMDAT investigates aversive memory and anxiety-like behavior simultaneously in rodents. Three-month-old male Wistar rats received bilateral infusions (1 μL per side) of saline, 8-OH-DPAT (5-HT1 agonist; 10 nmol), WAY100135 (5-HT1 antagonist; 0.9 nmol), ketanserine (5-HT 2 antagonist; 10 nmol), or fluoxetine (serotonin reuptake inhibitor; 1.6 nmol) into the BLA and were submitted to PMDAT training session 15 min later. In the test, 24 hr later, animals were re-exposed to the apparatus without the infusion of drugs, and aversive memory was evaluated. (a) 8-OH-DPAT did not affect memory or anxiety, but impaired avoidance behavior toward the aversive arm during training; (b) fluoxetine, WAY100135 and ketanserin impaired memory formation; (c) ketanserin decreased anxiety-like behavior; and (d) none of the treatments induced motor changes. The results showed that an increase in serotonin (5-HT) availability or the blockade of 5HT1A and 5HT2A BLA receptors impaired aversive memory formation. However, only 5HT2A receptor antagonism induced anxiolytic effects. Thus, both memory and anxiety-like behavior can be modified by changes in serotonergic transmission in the basolateral amygdala, but the effects on both phenomena seem to be mediated by different mechanisms related to serotonergic transmission.

This study aimed to determine whether pair housing after heroin self-administration reduces the incubation of craving, extinction, and reinstatement of heroin seeking. Single-housed female and male Sprague-Dawley rats underwent daily 6-hr heroin self-administration, wherein active lever presses produced a heroin infusion paired with light/tone cues. One day after self-administration, rats underwent a baseline cued-seeking test wherein active lever presses only produced light/tone cues. Immediately following this cued-seeking test, rats were either pair-housed with weight- and sex-matched naïve rat or remained single-housed for the rest of the study. For 14 days, rats remained in their homecages, after which they underwent a cued-seeking test to assess the incubation of craving compared to their baseline test. Rats then underwent extinction sessions followed by cue-induced and heroin-primed reinstatements. The findings reveal that pair-housed rats did not differ from single-housed rats in terms of the incubation of craving, extinction, or reinstatement of heroin seeking. Additionally, the results did not reveal any evidence of sex-based differences in the study. The present work indicates that pair housing during the forced abstinence period does not alter measures of heroin craving/seeking. These findings suggest that the chronic stress of single housing specifically during forced abstinence does not contribute to the degree of such measures.

Traditional dual-process models propose that stress can impair the ability to engage in goal-directed behavior so that people have to rely on habitual behavior. Support for this idea comes from a study by Schwabe and Wolf (2010), in which stressed participants continued to perform a learned instrumental behavior leading to a liquid after the liquid was devalued with a satiation procedure. Based on these findings, suboptimal behavior under stress is often seen as habitual. In the present study, we conducted a conceptual replication of the study by Schwabe and Wolf (2010). Instead of using a satiation procedure to achieve the outcome devaluation, we devalued outcomes through taste aversion. We did not replicate the pattern of findings by Schwabe and Wolf (2010). Our results indicate instead that stressed participants were sensitive to outcome values when the outcomes became truly aversive and hence that their behavior was goal-directed. This suggests either that (a) habitual processes are subject to boundary conditions or (b) the processes responsible for the findings of Schwabe and Wolf (2010) were never habitual to begin with. This may have far-reaching implications for explaining suboptimal behavior under stress in general.

However, the role of the NOPR in depression is not widely recognized. This study aims to evaluate behavioral and biochemical effects of the NOPR agonist Ro 65-6570 in mice submitted to social defeat protocol. The open-field test, social interaction test, and tail suspension test were applied to evaluate depressive behavior in male Swiss mice. Blood and brain tissue samples were obtained to evaluate the oxidative stress. The NOP agonist, Ro 65-6570 (1 mg/kg), or the social defeat stress reduced exploration rate in the open-field test. The social defeat stress and/or the NOP agonist also increased immobility time in the tail suspension test and the grooming time, as well as reduced the social interaction on the last day of social defeat protocol. Seven days after the end of the protocol, only the drug alone was able to affect the animals' interaction. Additionally, the NOP agonist increased the concentration of carbonyl groups (CGs) in hippocampus and malondialdehyde in serum. The stress of social defeat and the NOP agonist, together, increased malondialdehyde in animals' serum and prefrontal cortex, as well as increased the CGs concentration in the prefrontal cortex. These findings indicate a chronic depressive effect induced by the NOPR activation, sometimes regardless of the social defeat stress. We suggest that the NOPR signaling can activate pathways involved in cellular oxidative stress, contributing to the depression pathology.

The present study tested rhesus macaque monkeys with damage to the amygdala or OFC, along with sham-operated control monkeys, across six variants of novelty-based memory tasks. The results showed that monkeys with damage to the amygdala or OFC performed better overall than control monkeys across the tasks.

Researchers keen to understand how cannabis impairs cognition have, therefore, studied the behavioral effects of systemic injections of THC in animal models. However, cannabis contains multiple other cannabinoids which may critically modulate the resulting cognitive effects. Users also typically eat or smoke cannabis, leading to concern over the translational validity of pure THC injections. We, therefore, tested whether acute oral administration of two different commercially available cannabis extracts, marketed as <i>C. indica</i> or <i>C.</i> <i>sativa</i>, decreased male Long-Evans rats' willingness to exert greater cognitive effort in order to maximize reward earned, as expected from previous experiments using injected THC. Both oils were matched for THC and cannabidiol content. While both cannabis products slowed response times at higher doses, only <i>C. indica</i> oil at the highest dose administered (10 mg/kg THC) decreased the number of trials on which rats chose to complete high-effort/high-reward trials. Repeated dosing with a medium dose of either cannabinoid product (3 mg/kg THC) did not influence choice. Ex vivo analyses confirmed comparable levels of brain THC after <i>C. indica</i> or <i>C. sativa</i> administration. Although controversial in the field, these results support the suggestion that products marketed as different cannabis cultivars have dissociable cognitive effects that may not resemble pure THC and emphasize the importance of the route of administration in experimental design.
