Current neuroimaging techniques have very limited abilities to directly identify
and quantify neurotransmitters from brain sections. We have developed a
molecular-specific approach for the simultaneous imaging and quantitation of
multiple neurotransmitters, precursors, and metabolites, such as tyrosine,
tryptamine, tyramine, phenethylamine, dopamine, 3-methoxytyramine, serotonin,
GABA, glutamate, acetylcholine, and L-alpha-glycerylphosphorylcholine, in
histological tissue sections at high spatial resolutions. The method is employed
to directly measure changes in the absolute and relative levels of
neurotransmitters in specific brain structures in animal disease models and in
response to drug treatments, demonstrating the power of mass spectrometry imaging
in neuroscience.
