Study Guide: -no structures! 1. Voltage-Gated Ion Channels- what are the properties of these channels that contribute to synaptic transmission (ionselectivity; voltage-sensing, etc), what are the functional states. 2. Ligand-Gated Ion Channels- what are the properties of these channels that contribute to synaptic transmission (neurotransmitter selectivity; ion-selectivity; subunit composition, etc. ) that contribute to synaptic transmission. 3. Transporters- what are the different types of transporters and how do they each contribute to synaptic transmission.
