Excitatory synapses. The neurotransmitter at excitatory synapses depolarizes the postsynaptic membrane (of a neuron in this diagram). 1  Binding of acetylcholine to its receptors on the postsynaptic cell opens up ligand-gated sodium channels. 2  These allow an influx of Na + ions, reducing the membrane potential.xcitatory synapses.

Re: how often do you charge your battery. I let mine run down low before charging. Around 20% or so. On my iPhone 5S, I can go two days between charges and on my iPhone 6, I can go three days between charges. I am not a heavy user. Warrior_Bard likes this. let mine run down low before charging.
