Orexinergic neurons are predominantly located in the lateral hypothalamus (LH). However, the precise neural connectivity of these neurons across the brain remains insufficiently characterized. In this study, we used cell-specific anterograde and retrograde viral tracers to map the afferent and efferent connections of LH orexinergic neurons. Our results revealed that LH orexinergic neurons received extensive afferent inputs from cortical regions, including the primary motor cortex (M1) and secondary motor cortex (M2), the basal ganglia, including the caudate putamen (CPu), the diencephalon, such as the zona incerta (ZI) and reticular nucleus (Rt), and brainstem nuclei, including the ventral tegmental area (VTA) and locus coeruleus (LC). Simultaneously, the orexinergic neurons projected primarily to the telencephalon, including the bed nucleus of the stria terminalis (BNST) and lateral septum (LS), the diencephalon, including the medial preoptic nucleus (MPA) and lateral preoptic area (LPO), and the brainstem, such as the periaqueductal gray (PAG) and superior colliculus (SC). Among these, BNST, LS, MPA, and PAG were the primary projection targets of LH orexinergic neurons, whereas ZI, VTA, M1, and LC serve as their major input sources. Additionally, significant bidirectional projections were observed between LH orexinergic neurons and regions such as ZI and VTA, suggesting their potential roles in signal integration. These findings provide a detailed framework for the neural connectivity of LH orexinergic neurons, highlighting their potential involvement in mediating complex brain functions and neuropsychiatric disorders.</div></div>","PeriodicalId":9083,"journal":{"name":"Brain Research","volume":"1866 ","pages":"Article 149921"},"PeriodicalIF":2.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the ameliorative effects of TQ in an Aβ1-42-induced AD rat model. Male Wistar-Albino rats were divided into four groups: Control, AD, TQ-10 (10 mg/kg TQ), and TQ-30 (30 mg/kg TQ). TQ was administered orally for 7 days before and 10 days after Aβ1-42 injection into the hippocampus. Cognitive functions were assessed using the Passive Avoidance (PA) and Morris Water Maze (MWM) tests. After behavioral experiments, hippocampal cytokine (tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β)) levels, as well as astrocyte and microglial activation, are evaluated. TQ treatment reversed memory impairements in the AD group. Hippocampal TNF-α and IL-1β levels were elevated in the AD and reduced in TQ-treated groups. Immunohistochemical analysis revealed that the increased reactivity of glial fibrillary acidic protein (GFAP) and ionized calcium-binding adapter molecule 1 (Iba1) in the AD group was significantly attenuated by TQ treatment. Both 10 mg/kg and 30 mg/kg doses of TQ administration improved cognitive performance, reduced neuroinflammation, and mitigated glial activation in an Aβ-induced AD rat model.

This self-protective mechanism reduces the likelihood of accidental interactions with dangerous objects. However, habituation can diminish the motor interference effect over time, potentially increasing the risk of unsafe behaviors. To address this issue, the present study introduces a motor inhibition training protocol designed to counteract habituation effects by targeting specific stimuli. A prime-target grasping consistency judgment task was used as both a pre-test and post-test to evaluate the effectiveness of a 10-session Go/No-Go training program. The training used target stimuli identical to those in the judgment task, with the goal of enhancing individuals’ ability to inhibit responses to specific dangerous stimuli. The results demonstrated that the training not only mitigated the impact of habituation but also significantly prolonged reaction times to dangerous stimuli, indicating a dehabituation effect. Furthermore, Event-Related Potential analyses revealed that although the training exclusively employed dangerous stimuli as the No-Go condition to enhance inhibition of dangerous objects, the post-test results showed enhanced conflict monitoring and motor inhibition processing for both dangerous and safe stimuli within the experimental group. From a practical perspective, the dangerous (No-Go) stimuli used in the training task could be replaced with real-world dangerous objects relevant to specific work environments to strengthen the motor interference effect. This approach may offer a promising motor inhibition training strategy for reducing unsafe behaviors in real-world settings.</div></div>","PeriodicalId":9083,"journal":{"name":"Brain Research","volume":"1866 ","pages":"Article 149903"},"PeriodicalIF":2.6,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144933201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
