  • Connectivity defines the distinctive anatomy and function of the hand-knob area
    by Ahmad Beyh on 6 Settembre 2024

    Control of the hand muscles during fine digit movements requires a high level of sensorimotor integration, which relies on a complex network of cortical and subcortical hubs. The components of this network have been extensively studied in human and non-human primates, but discrepancies in the findings obtained from different mapping approaches are difficult to interpret. In this study, we defined the cortical and connectional components of the hand motor network in the same cohort of 20 healthy...

  • Mirror movements in multiple sclerosis -a clinical, electrophysiological, and imaging study
    by Korbinian Holzapfel on 6 Settembre 2024

    CONCLUSIONS: MM are common in MS and can easily be detected through bedside testing. As MM are associated with fatigue, they might indicate fatigue in MS. It is possible that other cerebral structures, in addition to the corpus callosum, may contribute to the origin of MM in MS.

  • Personalized whole-brain activity patterns predict human corticospinal tract activation in real-time
    by Uttara U Khatri on 4 Settembre 2024

    CONCLUSION: Our results show for the first time that personalized whole-brain EEG activity patterns predict CST activation in real-time in healthy humans. These findings represent a pivotal step towards using personalized brain state-dependent TMS interventions to promote poststroke CST function.

  • Age and visual cortex inhibition: a TMS-MRS study
    by Molly Simmonite on 3 Settembre 2024

    Paired-pulse transcranial magnetic stimulation is a valuable tool for investigating inhibitory mechanisms in motor cortex. We recently demonstrated its use in measuring cortical inhibition in visual cortex, using an approach in which participants trace the size of phosphenes elicited by stimulation to occipital cortex. Here, we investigate age-related differences in primary visual cortical inhibition and the relationship between primary visual cortical inhibition and local GABA+ in the same...

  • Noninvasive brain stimulation to improve motor outcomes after stroke
    by Emma C J Savelon on 2 Settembre 2024

    PURPOSE OF REVIEW: This review highlights recent developments in noninvasive brain stimulation (NIBS) techniques and applications for improving motor outcomes after stroke. Two promising areas of development relate to deep brain neuromodulation and the use of single-pulse transcranial magnetic stimulation (TMS) within a prediction tool for predicting upper limb outcome for individual patients.

  • The reliability and validity of rapid transcranial magnetic stimulation mapping for muscles under active contraction
    by Nahian S Chowdhury on 30 Agosto 2024

    Rapid mapping is a transcranial magnetic stimulation (TMS) mapping method which can significantly reduce data collection time compared to traditional approaches. However, its validity and reliability has only been established for upper-limb muscles during resting-state activity. Here, we determined the validity and reliability of rapid mapping for non-upper limb muscles that require active contraction during TMS: the masseter and quadriceps muscles. Eleven healthy participants attended two...

  • The Impact of Potent Addictive Substances on Angiogenic Behavior: A Comprehensive Review
    by Laith Naser Al-Eitan on 9 Settembre 2024

    Angiogenesis, the formation of new vasculature from preexisting vasculature, is involved in the development of several diseases as well as various physiological processes. Strict cooperation of proangiogenic and antiangiogenic factors mediates the control of angiogenesis. The fundamental steps in angiogenesis include endothelial cell proliferation, migration, and invasion. Addictive substances, which are considered therapeutic candidates in research and medicine, are classified as natural...

  • Modeling impaired insight after drug use in rodents
    by Marios Chris Panayi on 9 Settembre 2024

    Impaired insight in substance use disorder has been argued to reflect a global deficit in using cognitive models to mentally simulate possible future outcomes. The process of mentally simulating outcomes allows us to understand our beliefs about their causes, that is, to have insight and thereby avoid potentially negative outcomes. However, work in humans cannot address whether impaired insight and its neural/neurochemical sequalae are present prior to the development of a substance use...

  • Frequent Cocaine Use is Associated With Larger HIV Latent Reservoir Size
    by Bradley E Aouizerat on 9 Settembre 2024

    CONCLUSIONS: Cocaine use may contribute to a larger replication competent HLR in CD4+ T cells among virologically suppressed women living with HIV. Our findings are important because women are underrepresented in HIV reservoir studies and in studies of the impact of cocaine use on outcomes among PLWH.

  • Sex-Specific ADNP/NAP (Davunetide) Regulation of Cocaine-Induced Plasticity
    by Yael Toren on 9 Settembre 2024

    Cocaine use disorder (CUD) is a chronic neuropsychiatric disorder estimated to effect 1-3% of the population. Activity-dependent neuroprotective protein (ADNP) is essential for brain development and functioning, shown to be protective in fetal alcohol syndrome and to regulate alcohol consumption in adult mice. The goal of this study was to characterize the role of ADNP, and its active peptide NAP (NAPVSIPQ), which is also known as davunetide (investigational drug) in mediating cocaine-induced...

  • Single nucleus/cell RNA-seq of the chicken hypothalamic-pituitary-ovarian axis offers new insights into the molecular regulatory mechanisms of ovarian development
    by Dong Leng on 8 Settembre 2024

    The hypothalamic-pituitary-ovarian (HPO) axis represents a central neuroendocrine network essential for reproductive function. Despite its critical role, the intrinsic heterogeneity within the HPO axis across vertebrates and the complex intercellular interactions remain poorly defined. This study provides the first comprehensive, unbiased, cell type-specific molecular profiling of all three components of the HPO axis in adult Lohmann layers and Liangshan Yanying chickens. Within the...

  • Effect of Plasmafiltration and Adsorption in Cocaine Abuse: A Case Report
    by N Coviello on 7 Settembre 2024

    Rhabdomyolysis is one of the principal causes of acute kidney disease. Multiple endogenous and exogenous causes could start this process: cocaine addiction, a social phenomenon present in our Country among young adults, is one exogenous causes. Natural stimulating alkaloid cocaine has toxic action on multiple systems, principally central nervous system and cardiovascular system. Etiopathogenesis is related either to changes in local and systemic hemodynamics, or to direct damage caused by...
