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.

I bought a car adapter charger with two USB ports for charging iPhone 5s and iPad 4 in my car. The charger has a rating of 3.1 AMPS. I assume if the two are connected at the same time the 3.1 AMP is divided equally until one or the other is charged, then the full 3.1 AMPs would go to the remaining port! WOuld tht be ok if you dont leave it on for extended period of time?
