the progress of brain ach content up to its maximum level is decided both by duration and degree of cns depression : in the moment of most distinctly marked brevinarcon -narcosis -- evident 2,5 min after i. v. injection ( 40 mg/kg ) -- the forebrain ach content merely is increased by about 15 % , but when anaesthesia is reduced considerably again -- 2,5 min later -- the ach content only reaches its maximum level .
