+- Spike if depolarized above threshold: to -50 mV
- -- Here the threshold is based only on the integration of Na+
+- Ca2+ enter
- -- The threshold is tuned during the spiketrain. Low threshold at rest, to increase sensitivity, threshold increase during spike to increase discrimination
- -- increase SpikeTrainTraces (fast at spike)
- -- increase Ca2+ traces
 - Repolarization to -70 mV:  ~1-2 ms: K⁺ exits (VG K⁺ channels open) ← NOT pumps!
--- fast pump which decreases Na+, we do not model K+
 - After-hyperpolarization: ~5-20 ms: K⁺ channels still open
--- must figure out how to deal with deoplarization
--- decrease SpikeTraintraces slow, only if away from spiketrain this is empty
