Histogram of mutual information values of virtual organisms with Non-Hebbian LTP synapses compared to randomly chosen synapses.

<p>A. Histogram of I(D;W) values of 250 randomly chosen synapses with var(W)>0 of different virtual organisms randomly chosen from the behavior- based evolutionary session. B. Histogram of I(D;W) values of 250 randomly chosen Non-Hebbian LTP pre- synaptic synapses of different virtual organisms randomly chosen from the behavior- based evolutionary session. I(D;W) is the mutual information between the synapse state and the distance of the closest mate. The Non-Hebbian LTP pre- synaptic synapses contained more information about the closest mate (T-test P<10⁻¹⁶). For more information about the way I(D;W) was calculated see the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003697#s4" target="_blank">Materials and Methods</a> sections.
