Delay connections handle sequential time

• The patterns in both experiments take place in time.

• We must represent the relationships between elements that happen at different points in time.

• It is convenient, though maybe not necessary, to turn sequences, or subsequences, into static patterns.

• A standard approach to handling sequential time is time-delay connections. A connection with delay d > 0 causes the unit at the receiving end to respond to the activation that the unit at the sending end had d time steps before.
