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.

Apple's official advice for the quickest charge is to connect the device to a power outlet using the USB cable that came with the device and an Apple USB power adapter..f you don't want to hit the power button, then putting your handset in Airplane Mode (from the Settings menu) will stop your phone looking for cellular and Wi-Fi signals and can speed up the process. At the very least, try not to use your phone while it's on charge.
