Further, higher connectivity within the left hemisphere was also observed for the left-lateralized critical cortical regions of negative affect. Our study also revealed the association of emotion and memory-related subcortical-cortical interactions in positive and negative affect. Right amygdala-right thalamus-frontotemporal cortical areas emanated in positive affect, and right putamen-left hippocampus-frontotemporal cortical regions network stemmed for negative affect. Then, we show the involvement of basal-ganglia structures in approach-withdrawal dichotomy with tight coupling of right-caudate, left-accumbens with anterior cingulate, and insular regions for withdrawal/inhibition system. Further, distinct involvement of the insula (posterior) in affective states while insula (anterior) in approach/withdrawal systems builds up for the existence of a feedback loop between affective and approach/withdrawal systems.

Recently, we used AP5 and muscimol infusions to show that the DSub is required for CFC consolidation. The CFC component can be present in other learning tasks, such as step-through inhibitory avoidance (ST IA), which requires the dorsal hippocampus for acquisition and consolidation. This suggests that the DSub may be also involved in ST IA if the CFC component of the protocol is strong enough. [https://www.selleckchem.com/products/xmu-mp-1.html XMUMP1] Therefore, this study tested whether the DSub participates in ST IA acquisition and consolidation in male Wistar rats. Our data showed that pre-or posttraining infusions of AP5 or muscimol into the DSub did not affect ST IA acquisition and consolidation. We discuss the present results in relation to our previous findings, which showed the involvement of the DSub in CFC consolidation, and highlight some reasons that may explain the divergent results between the tasks. First, we note the possibility to escape from the unconditioned stimulus that occurs in ST IA, but not in CFC. We also suggest that the instrumental component of ST IA seems to be more prominent than the CFC one. Finally, we consider the possible influence of aspects of anxiety present in the ST IA, but not in CFC. These possible interpretations provide a broad framework in respect of the present results and raise new questions that demand further studies exploring the DSub function in inhibitory avoidance.

This study examined relapse-like behavior in male and female alcohol-preferring iP rats following punishment-imposed voluntary abstinence to alcohol seeking. We focused on alcohol seeking in the punishment-associated environment after prolonged abstinence. Finally, we sought to understand the predictability of relapse-like behavior by examining AUD comorbidities, namely, anxiety-like behavior and the response to repeated, moderate punishment. We found no sex differences in operant self-administration of alcohol. However, we did find a reduced propensity to relapse in the punishment-associated environment in female rats following prolonged abstinence. Relapse propensity was associated with the response to punishment during operant training, but not prior anxiety-like behavior. Together these results highlight the importance of studying sex differences in relapse to alcohol seeking. In addition, the behavioral response to a negative consequence may be a predictor of relapse, particularly in females. Improving our understanding of the sexually dimorphic responses in alcohol seeking may be a powerful tool for designing personalized, or at least sex-specific, approaches to treatment and rehabilitation programs.

OR as a phenotype has been shown to predict both direct drug proclivity in female rats and behaviors indirectly related to drug proclivity in male rats, but no extant research has compared males and females in terms of their OR behavior or its notable substrates. As females are at increased risk for substance abuse, and the ovarian hormone estradiol is often cited as a driving factor for this predilection, it is important to characterize sex differences between males and females and explore what, if any, contribution estradiol has in behaviors which predict substance abuse. In these experiments, male and female rats [intact or ovariectomized (OVX) with/without estradiol replacement] were compared on a battery of behavioral tasks, including OR, novelty-seeking, attentional set-shifting, and ultrasonic vocalizations (USVs) to amphetamine treatment. Female rats, regardless of estradiol replacement, had higher OR scores than males. OR score was a predictor of attention impairments, and estradiol availability contributed to this relationship in females. Sex differences were not observed in novelty-seeking, attentional set-shifting, or USV response to amphetamine; however, estradiol replacement did alter the presentation of these behaviors.

While young adults respond to these stimuli in a highly synchronized manner [as indexed by intersubject correlations (ISC) in their neural activity], older adults respond more idiosyncratically. Here, we examine whether eye-movement synchrony (eye-ISC) also declines with age during movie-watching and whether it relates to memory for the movie. Our results show no age-related decline in eye-ISC, suggesting that age differences in neural ISC are not caused by differences in viewing patterns. Both age groups recalled the same number of episodic details from the movie, but older adults recalled proportionally fewer episodic details due to their greater output of semantic and false information. In both age groups, higher eye-ISC related to a higher proportion of internal details and a lower proportion of false information being recalled. Finally, both older and younger adults showed better cued recall for cues taken from within the same event than those spanning an event boundary, further confirming that events are stored in long-term memory as discrete units with stronger associations within than across event boundaries.
