Conditioned taste aversion (CTA) is used to study learned shifts in affect, and taste reactivity (TR) can effectively track the hedonic properties of appetitive and aversive tastants before and after CTA. While the infralimbic cortex (IL) and its projections to the nucleus accumbens (NAc) shell play a key role in learned negative affect, this role is unique to males. Here, we sought to determine if the prelimbic cortex (PrL) to nucleus accumbens (NAc) core circuit, another prefrontal cortex-accumbens system, tracks innate versus learned negative affect using electrophysiological (local field potential, LFP) methods in male and female rats. As expected, CTA elicited a hedonic shift from an appetitive to an aversive TR profile, regardless of sex. However, time-frequency analyses revealed differential activity in the PrL and NAc core during innate and learned negative affect across sex. Specifically, we found that beta oscillations in the NAc core encode learned negative affect in males, while neither brain region seems to be selectively attuned to innate or learned aversion in females. Importantly, LFP functional connectivity (coherence) indicated that the PrL-NAc core circuit does not track any aspect of learned negative affect in either sex but may be involved in innate aversion in males only. Collectively, these data provide a sex-specific understanding of real-time oscillatory signaling dynamics in the PrL and NAc core during innate versus learned negative affect.</div></div>","PeriodicalId":8823,"journal":{"name":"Behavioural Brain Research","volume":"480 ","pages":"Article 115404"},"PeriodicalIF":2.6,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142871172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional rodent delay discounting procedures require extensive training and frequent experimenter interaction, as rodents are tested in separate operant chambers away from their home cage.

During each session, we measured large reward preference, mean adjusted delay, and trial participation across multiple delays. Results showed that rodents exhibited discounting behavior after two weeks, with performance stability increasing at 7 weeks training with delay. We also evaluated the influence of altering the consecutive choice criteria (ccc), number of trial choices for a delay step to adjust up or down. Lower ccc (3 vs 8) increased both the number of delay steps encountered per session and task participation. Additionally, we examined the effects of pharmacological interventions, including the psychostimulant amphetamine and the dopamine D1 receptor antagonist, SCH23390. A high dose amphetamine reduced preference for large immediate and short delayed rewards and decreased the mean adjusted delay in a non-dose dependent manner, while SCH23390 did not affect task performance. Together, this novel automated self-adjusting procedure enables high-throughput collection of delay discounting data, with potential applications for investigating impulsivity across the lifespan.

We used pupil dilation as a neuropsychological correlate of arousal and accumulated fixations on a region (i.e. dwell time) to measure oculomotor attention capture. Results during the cue phase showed that pupil dilation under a deterministic, but not a stochastic reinforcement schedule tracked arousal from the magnitude of reward. In addition, dwell time was increased for the eventual choice and dwell-time was reduced under high reward. Taken together, results show that arousal and attentional capture by reward depends to some extent on reward certainty. Turning to reward outcome, pupil dilation was highest (and average dwell time was lowest) following Error feedback compared to correct rewarded feedback. Overall results show that uncertain reward cues may alter pupil-linked arousal and attention as compared to certain reward, highlighting the role of uncertainty as an important modulator affecting attention and reward processing in environments that demand cognitive flexibility.</div></div>","PeriodicalId":8823,"journal":{"name":"Behavioural Brain Research","volume":"480 ","pages":"Article 115403"},"PeriodicalIF":2.6,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142871174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers have focused on neurotransmitters in the brain to develop weight management drugs that regulate food intake. This review explores the literature on genetic influences on dopaminergic processes to determine whether genetic variation has an association with obesity in reward-responsive regions, including mesolimbic efferent and mesocortical areas. Various neurotransmitters play an essential role in regulating food intake, such as dopamine which controls through mesolimbic circuits in the brain that modulate food reward. Appetite stimulation, including primary reinforcers such as food, leads to an increase in dopamine release in the reward centers of the brain. This release is related to motivation and reinforcement, which determines the motivational weighting of the reinforcer. Changes in dopamine expression can lead to hedonic eating behaviors and contribute to the development of obesity. Genetic polymorphisms have been investigated due to their potential role in modulating the risk of obesity and eating behaviors.

This study examined the neuroprotective effects of taurine, an essential β-amino acid with antioxidant and antiinflammation properties, in Swiss male mice exposed to rotenone-induced PD. Mice (20–25 g) were grouped into seven groups (n = 9) and treated with taurine alone (5, 10 and 20 mg/kg, <em>p.o</em>) or levodopa (10 mg/kg, <em>p.o</em>) for 28 consecutive days following intraperitoneal co-administration of rotenone (1.5 mg/kg, in 5 % dimethylsulfoxide) for 14 alternate days. Open-field, rota-rod and hanging-wire motor performance and coordination tests were conducted on days 26–28. Oxidative stress and neuroinflammatory markers; levels of acetylcholinesterase enzyme activity, dopamine, and alpha-synuclein were assayed in the striatal and prefrontal-cortical regions alongside histological examinations. Rotenone significantly reduced latency to fall and akinesia-like behavior with several slip/error relative to vehicle groups. Taurine increased the latency to fall, notably improving motor coordination, locomotor deficit, and neuromuscular competence. Also, rotenone significantly increased malondialdehyde and nitrite; while decreasing acetylcholinesterase activity, glutathione, catalase, superoxide-dismutase, and glutathione-S-transferase levels in the striatum and prefrontal-cortex respectively, which were attenuated by taurine. Taurine increased dopamine levels in the striatum and prefrontal cortex dose-independently. Like carbidopa, taurine decreased alpha-synuclein, tumor-necrosis factor-α and interleukin-6 levels in the striatum and prefrontal-cortex. Additionally, taurine-reversed rotenone-induced neurodegeneration in the striatum and prefrontal cortex indicates neuroprotective function. Conclusively, taurine attenuates rotenone-induced PD-like behavior by enhancing the brain's antioxidant system, inhibiting pro-inflammatory cytokine release, reducing α-synuclein formation, and augmenting dopaminergic release in mice's brains.</div></div>","PeriodicalId":8823,"journal":{"name":"Behavioural Brain Research","volume":"480 ","pages":"Article 115397"},"PeriodicalIF":2.6,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142823786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
