Difference Between GABA A and GABA B?

 

[Pythagorean]

In what sense?

At the molecular level, A receptors are Cl- ion channels, B receptors activate metabolic pathways. So A directly affects electrophysical properties, B affects molecular network dynamics through G protein cascades (which shut down the neuron's ion reactivity and down-regulates adenyl cyclase).
