Gaba levels, the brain's primary inhibitory neurotransmitter, what does it actually do?

GABA receptor. Like many ligands, GABA binds to its specific receptor, the GABA receptor (with several subtypes). Depending on the location of the GABA receptor, binding of GABA modulates various signaling pathways in the body. Note that GABA receptors are also found in organs outside of the brain.
