Is GABA excitatory or inhibitory at the AIS?
... Despite the seemingly ideal positioning of GABAergic synapses on the AIS for inhibition, the actions of GABA directly depend on the balance of intracellular and extracellular chloride concentration. High levels of extracellular chloride cause it to rush into the cell upon GABA activation whereas ...
