Abstract

The incorporation of [U-¹⁴C]glucose into acetylcholine (ACh) by tissue prisms incubated in a high K⁺ medium is unexpectedly well preserved in human brain obtained 30-45 min after death. The assay of this rare material provides the first data on ACh synthesis, as well as overall glucose oxidation (assessed by trapping ¹⁴CO₂), in non-neocortical regions of human brain. The rates of ACh synthesis were similar in the hippocampus and neocortex (except for occipital lobe material which was low in cholinergic activity), whereas synthesis was approximately 4-fold higher in the caudate nucleus.
