Summary of synaptic distribution observed in evolved network.
(A) Summary of general characteristics, labeled as ‘typical’, of synaptic distribution observed in evolved network in 12 different simulations. Results of certain simulations unambiguously differed from ‘typical pattern’; these pattern are labeled as ‘clear exceptions’ and are listed as well. Pattern found in remaining simulations conformed to the ‘typical pattern’ with minor variations. (B) A visual representation of ‘typical connectivity pattern’ summarized in table (A), assuming that neurons rich with outgoing synapses predominantly connect to neurons rich with incoming synapses. Note that (B) indicates only predominant connectivity pattern among various kind of neurons; see section 3.2.1 for further explanation. Inhibitory ‘activated region’ neurons largely remain silent in the evolved network, and hence are represented by a dashed circle in (B).
