Voltage-gated calcium (Cav) channels are a prerequisite for signal transmission at the first olfactory sensory neuron (OSN) synapse within the glomeruli of the main olfactory bulb (MOB). We showed previously that the N-type Cav channel subunit Cav2. 2 is present in the vast majority of glomeruli and plays a central role in presynaptic transmitter release. https://www.jmannino.com/
