… As an example we present the calcium-dependent plasticity model (CaDP) of (Shouval et al.…
Shouval was supported by a grant from the NIH (2P01-NS038310). Samuel S.-H. Wang was …

… where H(V) summarizes the voltage dependence as described by Jahr and Stevens (23),
P 0 = 0.5 is the fraction of NMDARs in the closed state that shift to the open state after each …

The receptive fields of visual cortical neurons are bidirectionally modified by sensory
deprivation and experience, but the synaptic basis for these changes is unknown. Here we …

… The animals had two days of monocular visual experience (12 h/12 h light/dark cycle), and
were then placed in the dark for a further two days to allow the effects of the TTX to wear off. …

… The learning rule implementation underlying on-chip synaptic plasticity is an adaptation
of a model proposed by Shouval, et al. (4) that relies on calcium dynamics in the cell to …

… to learn the timing for reward arriving over a large range of temporal delays (Figure 7H). …
i (postsynaptic) and j (presynaptic), h is the learning rate, and the delta function term indicates …

… The voltage dependence of the calcium current through the NMDARs is summarized by ℋ,
where ℋ(V) expresses the voltage dependence of the calcium current through the NMDARs. …

… (Shouval et al. 2002). Thus there is converging evidence for this calcium control hypothesis.
… In another paper (Shouval et al. 2002), we show the consequences of precise spike times …

… The values of the synaptic proto-weights are determined by the network dynamics and the
Hebbian plasticity function, H. Assuming an appropriate selection of H, L i,j p will be greater …
