This molecule is released by climbing fiber activation of Purkinje cells, and Huntington's disease is
 partially caused by the loss of cells that secrete this substance in the striatum. It is produced in a reaction
 that uses the enzymes GAD and pyridoxal phosphate, or vitamin B6 and its receptor works by widening a
 chloride channel, which in turn neutralizes norepinephrine. Benzodiazepenes and barbituates work by
 binding to receptors for this molecule, which is synthesized by decarboxylating glutamate. For 10 points,
 name this inhibitory mammalian neurotransmitter with a four letter abbreviation.
