Chronic METH use leads to neurotoxicity characterized by various molecular and structural alterations in the brain. This review article primarily aims to elucidate the mechanisms underlying METH‑induced neurotoxicity. METH's mechanism of action involves the inhibition of dopamine, serotonin, and norepinephrine reuptake, resulting in altered synaptic function. Prolonged METH exposure triggers oxidative stress, endoplasmic reticulum stress, mitochondrial dysfunction, impaired axonal transport, autophagy, and programmed cell death, ultimately contributing to neurotoxicity. These neurotoxic effects manifest as increased neuronal firing rate, disruptions in intracellular ion balance (Ca2+ and Na+), energy production imbalances, and excessive reactive oxygen species production. The blood‑brain barrier is compromised, leading to structural, functional, and neurochemical alterations, particularly in the fronto‑striatal circuit. While our comprehensive review addresses these intricate molecular and structural changes induced by METH, we also examined the latest therapeutic strategies designed to mitigate neurotoxicity. Our investigation sheds light on the critical need to comprehend the complex pathways underlying METH‑induced neurotoxicity and develop effective treatment approaches.","PeriodicalId":7032,"journal":{"name":"Acta neurobiologiae experimentalis","volume":"83 4","pages":"414-431"},"PeriodicalIF":1.4,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139465822","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}

Low‑frequency repetitive magnetic stimulation (rTMS) has been verified to suppress neural excitability and reduce seizures. Given its potential in modifying cortical activity, we aimed to investigate its impact on cognitive function in the context of epilepsy, a condition where the use of rTMS has not been extensively explored. However, the influence on cognitive function has not yet been investigated. Therefore, this study aimed to investigate the effects of low‑frequency rTMS on cognitive improvement in epileptic rats. Rats used in this study were randomly divided into five groups: the sham group, the epilepsy group, and three epilepsy groups treated with rTMS at different frequencies. Each group underwent the Morris water maze test to investigate hippocampus‑dependent episodic memory, to evaluate their cognitive performance. Further assessments included patch clamp and western blot techniques to estimate the synaptic function in the hippocampus. Comparison between groups showed that low‑frequency rTMS significantly reduced spontaneous recurrent seizures and improved spatial learning and memory impairment in epileptic rats. Additionally, rTMS remodeled the synaptic plasticity affected by seizures and notably enhanced the expression of AMPAR and synaptophysin. Low‑frequency rTMS can antagonize the cognitive impairment caused by TLE, and promote synaptic connections.","PeriodicalId":7032,"journal":{"name":"Acta neurobiologiae experimentalis","volume":"83 4","pages":"395-403"},"PeriodicalIF":1.4,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139465816","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}

CircRNAs have been indicated to act as a key mediator in anesthetic neurotoxicity. This study focused on the effect of circ_0016760 on sevoflurane‑induced neurological impairment. The GEO database (GSE147277) and RT‑qPCR were used to predict and measure the circ_0016760 expression. The interaction of circ_0016760 and miR‑145 was verified by dual‑luciferase reporter assay. The CCK‑8 assay, flow cytometry, ELISA, ROS kit, MWM test were carried out to measure the cell viability, apoptosis, inflammation indicators, ROS level, and cognitive and memory function of the rats. Sevoflurane exacerbated neurotoxicity by restraining cell viability, inducing cell apoptosis, neuroinflammation, and ROS generation, and causing learning and cognitive dysfunction. Circ_0016760 expression was increased in POCD patients from the GEO database and upregulated after sevoflurane exposure. miR‑145 was a target miRNA of circ_0016760. Silencing of circ_0016760 weakened the effect of sevoflurane on cell viability, cell apoptosis, inflammation‑related factors, oxidative stress, which could be reversed by miR‑145 inhibitor. The animal experiments results showed that circ_0016760 played a protective effect on regulating the cognitive behavior of sevoflurane‑treated aged rats, expression of inflammation cytokine, and oxidative stress factors through targeting miR‑145 in sevoflurane‑treated aged rat's hippocampal neurons. Our results revealed that silencing of circ_0016760 attenuated sevoflurane‑induced hippocampal neuron injury by regulating miR‑145 expression, which may provide potential insights into the treatment of sevoflurane‑induced neurological impairment.","PeriodicalId":7032,"journal":{"name":"Acta neurobiologiae experimentalis","volume":"83 4","pages":"377-385"},"PeriodicalIF":1.4,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139465833","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}

A history of performing these tasks may be reflected in spontaneous brain activity. Here, we examined the relationship between the complexity (temporal dynamics) of resting‑state EEG (rsEEG) signal, assessed using the multivariate MultiScale Entropy (mMSE) algorithm, and the perception of event ordering, indexed by a visual temporal order threshold (TOT), i.e., the minimum duration necessary to correctly identify the before‑after relation between two stimuli. Healthy adolescents and young adults performed a psychophysical task measuring the TOT and underwent an eyes‑closed rsEEG study. The features of mMSE vectors, namely the area under curve (AUC) that represents total signal complexity, as well as the MaxSlope and the AvgEnt, corresponding to the entropy at fine‑ and coarse‑grained timescales, respectively, were obtained for the central (midline), anterior, middle and posterior channel sets. The greater the AUC and AvgEnt values in the central, left and right posterior areas, and the higher AUC in the right middle region, the higher the TOT. The most significant relationships were found for the midline electrodes (Fz, Cz, Pz, Oz). There were no significant correlations between the MaxSlope values and the TOT. To the best of our knowledge, this is the first study demonstrating that spontaneous EEG signal complexity is associated with the temporal order perception of two stimuli presented in rapid succession. Our findings may indicate that low total and coarse entropy levels of rsEEG signal are beneficial for visual temporal order judgments.","PeriodicalId":7032,"journal":{"name":"Acta neurobiologiae experimentalis","volume":"83 4","pages":"359-376"},"PeriodicalIF":1.4,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139465830","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}

It is a highly dynamic process in which dendritic branches form and regress until mature connectivity is achieved. Thereafter, dendritic branches are considered stable and do not undergo substantial rearrangements, although several exceptions have been described in the literature. After this long period of relative stability, significant changes in dendritic branching occur when the brain begins to age. Several neurological diseases, occurring both during development and in adulthood, have severe effects on the morphology of dendritic arbors, often associated with intellectual dysfunction. The molecular mechanisms of dendritogenesis are fairly well described. In contrast, knowledge of the molecular mechanisms of dendritic arbor stabilization and pathology‑induced instability is still quite incomplete, and several important questions remain unanswered. We describe the dynamic changes during development and adulthood and in different pathologies. Whenever possible, we also provide details on the molecular mechanisms behind dendritic dynamics and stability.","PeriodicalId":7032,"journal":{"name":"Acta neurobiologiae experimentalis","volume":"83 4","pages":"331-358"},"PeriodicalIF":1.4,"publicationDate":"2023-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139465792","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}
