Abstract
: A study of post‐mortem human brain was undertaken to establish whether there is any evidence for lateral asymmetry of neurotransmitters. Choline acetyltransferase, glutamic acid decarboxylase, α‐aminobutyric acid, dopamine and noradrenaline were measured in nine comparable areas from the left and right hemispheres of normal post‐mortem human brain. Only nigral GABA showed a left‐right difference at a significance level of 5%. These negative post‐mortem findings suggest that chemical laterality is unlikely to be an important source of error in human post‐mortem studies.
