We found inherited resilience to 3 months of CCH in males is maternally mediated (<i>p</i> = .006). Statistically, we observed a strong trend for the paternal germline to contribute as well (<i>p</i> = .052). We also found that, in contrast to what is widely observed in males, females display intact recognition memory (<i>p</i> = .001) after 3 months of CCH, revealing a heretofore unidentified sexual dimorphism with respect to cognitive impact during disease progression. Overall, results of our study strongly implicate epigenetic changes in maternal germ cells, induced by our repetitive systemic hypoxic stimulus, contributing to a modified differentiation program capable of establishing a dementia-resilient phenotype in adult male first-generation progeny.

Two important factors that influence susceptibility to addiction are individual differences in personality traits and biological sex. The influence of traits on addiction-like behavior is well-characterized in preclinical models of cocaine self-administration, but less is understood in regards to opioids. How biological sex influences trait susceptibility to opioid self-administration is likewise less studied than psychostimulants. Thus, we sought to elucidate how biological sex and several addiction-relevant traits interact with the propensity to self-administer the opioid remifentanil. We first screened female (<i>n</i> = 19) and male (<i>n</i> = 19) rats for four addiction-relevant traits: impulsivity, novelty place-preference, anxiety-like behavior, and attribution of incentive value to reward cues. Rats were then trained to self-administer remifentanil in a \"conflict model\" of drug self-administration. Rats had to endure an electric shock to access the response manipulandum that triggered an intravenous infusion of remifentanil. In male rats, high anxiety-like behavior was positively correlated with the number of drug infusions if the shock level was low or completely absent. In females, sign-tracking was predictive of greater resistance to punishment during drug seeking; an effect that was mediated by anxiety-like behavior. Females consumed more remifentanil under all conditions, and their drug seeking persisted in the face of significantly greater current than males. These findings demonstrate that the influence of behavioral traits over the propensity to self-administer opioids is dependent upon biological sex.

To investigate this question directly, we prepared two group of monkeys. First, the contralateral frontal-hippocampal split group (CFHS) received a unilateral lesion of the hippocampus and surrounding posterior parahippocampal cortices (H +), combined with a <i>contralateral</i> lesion of the dorsolateral prefrontal cortex (DLPFC) plus transection of the corpus callosum and anterior commissure. This preparation functionally \"disconnects\" the remaining intact H + from the sole intact DLPFC in the opposite hemisphere. As a surgical control group, a second set of animals, the ipsilateral frontal-hippocampal split group, was prepared with a <i>unilateral</i> lesion of the DLPFC and an <i>ipsilateral</i> H + lesion together plus transection of the corpus callosum and anterior commissure. This preparation matches the locus and extent of damage in the cross-lesion group but allows the intact H + and intact DLPFC to interact ipsilaterally. Following recovery from surgery, all animals were then tested on the delayed nonmatching to sample task (DNMS), a test of recognition memory. The crossed-lesion split-brain group (CFHS) was markedly impaired on DNMS in both acquisition (rule learning) and performance over delays (recognition memory).

The same is true for aversive conditioning; stimuli previously associated with an aversive outcome also bias attention, suggesting that motivational salience guides attention. Most research that supports this conclusion has manipulated monetary gain-a secondary reinforcer-for reward learning, and electric shocks-a primary punisher-for aversive conditioning, making it difficult to directly compare their influence on attention. Therefore, in the present study, we matched for reinforcer dimensions by using primary taste as reinforcers/punishers and assessed their influence on attention. In a training phase, participants learned to associate three colors with sweet juice (reward), salt water (aversive), and no outcome (neutral), respectively. The two primary reinforcers were equated for valence based on choices made in a prior decision-making task. In a later test phase, these three colors were used for targets and distractors in a task in which participants oriented to a shape-defined target. An attentional bias in favor of the aversively conditioned and reward-associated colors was evident when comparing to the neutral color. Importantly, a direct comparison of rewarded and aversive stimuli revealed no significant differences. These results suggest that when matched for reinforcer dimensions and valence, reward and aversive outcomes bias attention in a similar manner and their effects are comparable, providing further evidence in support of the motivational salience account of learning-dependent attention.

Consistently, substance abuse in this stage has been found to induce persistent changes in brain responsiveness to future drug challenges. Nowadays, heavy episodic alcohol consumption during adolescence, also known as binge-drinking behavior, is a growing concern in modern societies. On the other hand, alcohol is well known to act as a gateway drug, that is, it promotes the individual's craving for consumption of other drugs of abuse. With this in mind, we aimed to assess whether adolescent ethanol exposure could alter the development of tolerance and dependence to morphine, as an available common opioid drug. Tail flick test was used to measure thermal nociceptive changes in adult male Wistar rats undergone ethanol/vehicle exposure during adolescence. Furthermore, morphine withdrawal syndrome was induced by naloxone injection, and behavioral signs were recorded for 20 min. It was found that adolescent ethanol intake facilitates morphine analgesic tolerance and decreases baseline latency; however, the severity of dependence is not significantly altered. Moreover, we found that 15 days of treatment with omega-3 fatty acids (O3) prevents the mentioned ethanol-induced changes suggesting a therapeutic potential for this compound. O3 supplementation, as an inexpensive and noninvasive method, may assist the clinicians to reverse the adverse effect of alcohol binge drinking on adolescents' brains and to reduce the vulnerability to drug exposure in adulthood.

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.

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.
