스트레스에 의한 Long-term potentiation (LTP)의 저하를 감소시키는 리튬의 효과
… structural remodeling. Enhancement of LTP by lithium treatment was reported by an in vitro study. On the other hand, some studies have reported the attenuation of effects of chronic stress situation. In this study, we investigated whether lithium attenuated or prevented the …

Direct current stimulation modulates LTP and LTD: activity-dependence and dendritic effects
… plasticity I induced long-term potentiation (LTP) and depression (LTD) at Schaffer collateral synapses in CA1 of rat hippocampal slices. When induction was paired with concurrent DCS, the resulting plasticity was biased towards potentiation, such that LTP was enhanced and LTD was reduced. …

Super-resolution imaging of glutamate receptors in cultured hippocampal neurons under basal and LTP conditions
… and chemically induced long-term potentiation (cLTP) condition, where synaptic strength is increased by activation of NMDARs from glycine that triggers changes in the number and structure of AMPARs. With three-dimensional super-resolution microscopy (7~16 nm resolution in x-y and 20~32 nm …

Low-Frequency-Induced Synaptic Potentiation: a Paradigm Shift in the Field of Memory-Related Plasticity Mechanisms?
… synaptic strength (i.e., long-term potentiation, LTP; long-term depression, LTD) mediates learning and memory processes. Typically, high-frequency stimulation (HFS) of afferent fibers results in LTP, while low-frequency stimulation (LFS) elicits LTD. In stark contrast to this “HFS- LTP vs. …

Functional implications of behavioral experience effects upon the rat visual cortex
… evoked response showed long-term potentiation (LTP), following low frequency tetanization, with two expression patterns, one possibly mediated by voltage dependent calcium channels (VDCCs) and the other by VDCCs and N-methyl-D-aspartate (NMDA) glutamate receptors. In search for functional …

CaMKII at a central synapse : α-calcium/calmodium protien kinase II and synaptic plasticity at CA3 Schaffer collateral -- CA1 synapses in the mammalian hippocampus
Long term potentiation (LTP) of synaptic transmission at the CA3-CA1 hippocampal synapse is a model synaptic plasticity mechanism that may underlie hippocampal dependent learning and memory. Inhibition of post-synaptic calcium/calmodulin protein kinase II (CaMKII) has been shown to block LTP, and a …

Women's decisions and decisional conflict regarding long term hormone replacement therapy.
Long term preventive hormone replacement therapy (LTP-HRT) is attracting considerable attention for its potential in reducing the incidence of coronary heart disease and osteoporosis associated fractures in post-menopausal women. The study objectives were: (1) to describe women's decisions and …

Exploring Learning through Play in Mexican Preschool Education: Teachers' Perspectives and Practices
… 2018, 2024). As a result, Learning through Play (LtP) has been incorporated into early years national curricula in several countries, and teachers have been encouraged to adopt and integrate it into their pedagogical practices (Pramling Samuelsson & Fleer, 2009). However, the way teachers …

Novel roles of the endocannabinoid system in modulating synaptic plasticity
… protocol produces long-term potentiation (LTP) that is modulated by eCBs in both mice and rats; but surprisingly, the roles played by eCBs differ greatly between species. In rats, 10 Hz LTP requires CB1 receptor activation, as it is completely abolished by the CB1 antagonists AM251 and …

The induction of long-term potentiation attenuates kainic acid-induced excitotoxicity
… is required for the long term potentiation (LTP) and long term depression (LTD) of excitatory synaptic transmission at hippocampal CA1 synapses, and plays an important role in learning and memory. In addition, it is accepted that the over-activation of NMDARs leads to the neurotoxicity …

The Role of Ubiquitin-Proteasome-Mediated Proteolysis in Long-term Synaptic Plasticity
… plasticity, late-phase long-term potentiation (L-LTP), our work reveals intricate interactions between proteolysis, protein synthesis in the dendrites and gene transcription in the nucleus. Previously, we showed that the early induction phase of L-LTP, which depends on local protein synthesis …

Estrogenic modulation of excitatory synaptic transmission at hippocampal temporoammonic-CA1 synapses
… that estradiol (E2) can induce a robust LTP at juvenile TA-CA1 synapses. E2-induced LTP at these synapses involves activation of ERα and GPER1 as selective agonists of these receptors mimic the effects of E2 at TA-CA1 synapses. However, E2-induced LTP does not involve ERβ, and …
