Ionotropic GABA Receptors and Distal Retinal ON and OFF Responses
Figure 2
A schematic representation of ionotropic GABA receptors. Five subunits form a transmembrane chloride ion channel. The subunit composition of GABAA (left) and GABAC receptor (right) is indicated. The locations of the binding sites for GABA, GABA modulators (barbiturates and benzodiazepines) and antagonists (picrotoxin) are also shown.
