Seizure proneness and neurotransmitter uptake.
The ability of midbrain homogenates from two strains of mice to accumulate several putative neurotransmitters, or their precursor in the case of acetylcholine, has been examined. The high-affinity transport mechanisms toward glutamate, GABA, dopamine, and glycine were similar in both strains. The seizure-prone DBA21BG strain had a significantly higher capacity to transport choline than did the relatively seizure-resistant C57BL/6 IBC mice. Howaver, no difference in the density of muscarinic binding sites in the two mouse strains was found.
