The effect of imbalance between potentiation and depression on the capacity measures for hard-bound plasticity.

<p>A. The Information capacity showing the theory (black) as well as simulations for 10, 100, 1000, and 10000 synapses for (blue, violet and magenta). In contrast to the balanced case () the capacity depends on the number of synapses. A larger synaptic update always decreases capacity in the balanced case, but can improve capacity in the imbalanced case (dashed curve, , ). B. Memory lifetime decreases when potentiation and depression are imbalanced. The memory lifetime was optimized w.r.t for every setting of and .
