thus , at all the frequencies studied ( 1-30 hz ) , [ ( 3 ) h ] -ach synthesis was greatly increased and [ ( 3 ) h ] -phosphorylcholine was reduced , the maximum effects occurring at 3 hz.9 when ganglia were incubated with a high concentration ( 100 mum ) of [ ( 3 ) h ] -choline ( low affinity uptake ) , a different pattern of metabolism was observed .
