Timing circuit. GeorgeDileep HawkinsJeff 2009 <p>The same circuit as shown in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1000532#pcbi-1000532-g005" target="_blank">Figure 5</a> with the addition of circuitry for incorporating variable time delays between elements of the Markov chains. The pentagon neurons represent the belief at each node. The rounded rectangle neurons represent the belief at each node at the appropriate time delay. An external variable time delay mechanism provides time duration information to all the neurons involved in encoding sequences.</p>
