'''Sag and spike times match great, but AHPs way to big.  
Perhaps need another channel?  Is a second KA current needed?
Could KA replace KDr?  Check the "optimal" conductance
Would additional calcium currents help?  What is known about them?

observation: strong Kv3 associated with nice looking AHPs, and as it decreases AHPs look worse
------>>>> evaluate Kv3 inactivation - too strong?
     spike height decreases and NaS decreases along with AHP decrease.  Symptom or cause?
    Z gate of NaS decreases slowly across simulation - this could be causal, BUT
    eliminating NaS Zgate doesn't change this.
