     Todo:
-        [] implement dormant connection
+        [1] use abs(wRec) suring neuron init
+        [2] implement dormant connection and pruning machanism. the longer the training the longer 
+            0 weight stay 0. 
         [] using RL to control learning signal
         [] consider using Dates.now() instead of timestamp because time_stamp may overflow
         [] training should include adjusting α, neuron membrane potential decay factor
