Kv3.1 is a potassium channel that functions in action potential repolarisation in fast-firing neurons. Kv3.1 is not a classic cannabinoid receptor but its activity is modulated by cannabinoids.

Cav3.3 is a calcium channel of the T-type that is involved in many brain processes. Contrary to other calcium channels Cav3.3 is activated by relatively low/negative voltages.
