    Spinal Excitability Changes after Transspinal and Transcortical Paired Associative Stimulation in Humans by Maria Knikou

    Published 2017-01-01
    “…These findings support the notion that transspinal and transcortical PAS has the ability to alter concomitantly cortical and spinal synaptic activity. Transspinal and transcortical PAS may contribute to the development of rehabilitation strategies in people with bilateral increased motoneuronal excitability due to cortical or spinal lesions.…”

    Bifidobacterium breve BB05 alleviates depressive symptoms in mice via the AKT/mTOR pathway by Yanni Pan, Qingling Huang, Yuan Liang, Yuwuqi Xie, Fang Tan, Xingyao Long

    Published 2025-01-01
    “…Mechanistic analysis revealed that BB05 exerts antidepressant effects by activating the AKT/mTOR signaling pathway in the prefrontal cortex, promoting neuroprotection, neurogenesis, and synaptic plasticity.DiscussionThese findings suggest that BB05, particularly at higher doses, effectively alleviates CUMS-induced depressive behaviors and improves physiological outcomes, supporting the use of probiotics as a potential treatment for depression by targeting the AKT/mTOR pathway.…”

    Impact of Time Delay in Perceptual Decision-Making: Neuronal Population Modeling Approach by Urszula Foryś, Natalia Z. Bielczyk, Katarzyna Piskała, Martyna Płomecka, Jan Poleszczuk

    Published 2017-01-01
    “…Using numerical simulations, we demonstrate that for small synaptic delays the decision-making process depends directly on the strength of supplied stimulus and the system correctly identifies to which population the stimulus was applied. …”

    SPICE-Level Demonstration of Unsupervised Learning With Spintronic Synapses in Spiking Neural Networks by Salah Daddinounou, Anteneh Gebregiorgis, Said Hamdioui, Elena-Ioana Vatajelu

    Published 2025-01-01
    “…Unlike conventional neuromorphic hardware that relies on simple weight mapping post-off-line training, our approach emphasizes continuous, unsupervised learning, ensuring an energy efficiency of 11.2nW per synaptic update during training and as low as 109fJ/spike during inference.…”

    Functional Role of Adult Hippocampal Neurogenesis as a Therapeutic Strategy for Mental Disorders by Heechul Jun, Syed Mohammed Qasim Hussaini, Michael J. Rigby, Mi-Hyeon Jang

    Published 2012-01-01
    “…Adult neurogenesis, the process of generating new neurons from neural stem cells, plays significant roles in synaptic plasticity, memory, and mood regulation. In the mammalian brain, it continues to occur well into adulthood in discrete regions, namely, the hippocampus and olfactory bulb. …”

    Effects of Diet on Brain Plasticity in Animal and Human Studies: Mind the Gap by Tytus Murphy, Gisele Pereira Dias, Sandrine Thuret

    Published 2014-01-01
    “…In particular, we evaluate the gap in mechanistic understanding between recent findings from animal studies and those human studies reporting that these dietary factors can benefit cognition, mood, and anxiety, aging, and Alzheimer’s disease—with focus on the enhancement of structural and functional plasticity markers in the hippocampus, such as increased expression of neurotrophic factors, synaptic function and adult neurogenesis. Lastly, we discuss some of the obstacles to harnessing the promising effects of diet on brain plasticity in animal studies into effective recommendations and interventions to promote healthy brain function in humans. …”

    FOXP2-immunoreactive corticothalamic neurons in neocortical layers 6a and 6b are tightly regulated by neuromodulatory systems by Guanxiao Qi, Danqing Yang, Fernando Messore, Arco Bast, Felipe Yáñez, Marcel Oberlaender, Dirk Feldmeyer

    Published 2025-01-01
    “…These L6 FOXP2+ PCs project exclusively to the thalamus, with L6a PCs targeting first-order or both first- and higher-order thalamic nuclei, whereas L6b PCs connect only to higher-order nuclei. Synaptic connections established by both L6a and L6b FOXP2+ PCs have low release probabilities and respond strongly to acetylcholine (ACh), triggering action potential (AP) trains. …”
