The Role of CaV2.1 Channel Facilitation in Synaptic Facilitation

The role of synaptic facilitation in coincidence spike detection

Using a realistic model of activity dependent dynamical synapses and a standard integrate and fire neuron model we study, both analytically and numerically, the conditions in which a postsynaptic neuron efficiently detects temporal coincidences of spikes arriving at certain frequency from N different afferents. We extend a previous work that only considers synaptic depression as the most import...

Role of Synapsin in Long-term Synaptic Facilitation in Aplysia

Phase Precession Through Synaptic Facilitation

Phase precession is a relational code that is thought to be important for episodic-like memory, for instance, the learning of a sequence of places. In the hippocampus, places are encoded through bursting activity of so-called place cells. The spikes in such a burst exhibit a precession of their firing phases relative to field potential theta oscillations (4-12 Hz); the theta phase of action pot...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

New and corrected simulations of synaptic facilitation.

Tang et al. (2000) demonstrated that, at the crayfish neuromuscular junction, both the accumulation and the decay properties of short-term synaptic facilitation (STF) are strongly affected by the addition of a fast high-affinity Ca buffer, suggesting a role of residual free Ca in the induction of STF. The authors proposed that the experimental results can be explained by a secretion model with ...
