  2. Long-term potentiation - Wikipedia

    en.wikipedia.org/wiki/Long-term_potentiation

    Long-term potentiation (LTP) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse. Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory. In such studies, electrical recordings are made from cells and plotted in a graph such as this one.

  3. BCM theory - Wikipedia

    en.wikipedia.org/wiki/BCM_theory

    According to the BCM model, when a pre-synaptic neuron fires, the post-synaptic neurons will tend to undergo LTP if it is in a high-activity state (e.g., is firing at high frequency, and/or has high internal calcium concentrations), or LTD if it is in a lower-activity state (e.g., firing in low frequency, low internal calcium concentrations).

  4. Early long-term potentiation - Wikipedia

    en.wikipedia.org/wiki/Early_long-term_potentiation

    It has been proposed that long-term potentiation is composed of at least two different phases: [4] protein synthesis-independent E-LTP (early LTP) and protein synthesis-dependent L-LTP (late LTP). A single train of high-frequency stimuli is needed to trigger E-LTP that begins right after the stimulation, lasting a few hours or less, and ...

  5. LTP induction - Wikipedia

    en.wikipedia.org/wiki/LTP_induction

    The induction of NMDA receptor-dependent long-term potentiation (LTP) in chemical synapses in the brain occurs via a fairly straightforward mechanism. [ 1 ] [ 2 ] A substantial and rapid rise in calcium ion concentration inside the postsynaptic cell (or more specifically, within the dendritic spine ) is most possibly all that is required to ...

  6. Homosynaptic plasticity - Wikipedia

    en.wikipedia.org/wiki/Homosynaptic_plasticity

    LTP can be induced from dendrites severed from the soma of the post-synaptic target neuron. Contrarily, LTP can be blocked in these dendrites by protein synthesis blockers, such as Endomyacin, which further indicates a site for local protein synthesis. This evidence shows local protein synthesis is necessary for L-LTP to be stabilized and ...

    In 2015, College Board partnered with Project Lead The Way in an effort to encourage STEM majors. [6] Students who have successfully passed at least three exams (one AP exam, one PLTW exam, and another AP or PLTW exam) are eligible to receive the AP + PLTW Student Recognition for one or more of the following: engineering, biomedical sciences, and computer science.
