although the enzyme activity did not differ very much between the various brain regions ( max . 15.4 ; min . 7.5 pmol ) , there were some areas in the brain with a more than average activity , i.e. , the lateral telencephalon ( 10.3 pmol ) , the nucleus preopticus ( 13.1 pmol ) , nucleus lateralis tuberis ( 11.0 pmol ) and nucleus recessus posterioris ( 12.0 pmol ) of the diencephalon , the tectum opticum ( 15.4 pmol ) and torus semicircularis ( 13.6 pmol ) of the mesencephalon , and the caudal cerebellum of the metencephalon ( 10.8 pmol ) .
