Abstract
  1. Catecholamines and 5-hydroxytryptamine were measured fluorimetrically in nervous tissue of cephalopod molluscs.2. The only catecholamines found present in nervous tissue of Eledone, Octopus and Sepia were dopamine and noradrenaline. The highest concentrations were found in the optic lobes and in the superior buccal lobe. The concentrations of dopamine and noradrenaline were smaller in other regions of the nervous tissue taken.3. 5-Hydroxytryptamine was also found in most of the regions investigated. The highest concentration was found in the inferior buccal ganglia and in the optic lobes.4. The administration of reserpine produced a marked decrease in the concentration of catecholamines and 5-hydroxytryptamine in octopod nervous tissue.5. These findings suggest that dopamine, noradrenaline and 5-hydroxytryptamine may function as neurotransmitters in cephalopod molluscs.
摘要
  1. 采用荧光法测定了头足类软体动物神经组织中的儿茶酚胺和5-羟色胺。

  2. 在艾氏章鱼、真蛸和乌贼的神经组织中发现的唯一儿茶酚胺是多巴胺和去甲肾上腺素。在视叶和上颊叶中发现的浓度最高。在所取神经组织的其他区域,多巴胺和去甲肾上腺素的浓度较低。

  3. 在大多数研究区域中也发现了5-羟色胺。在下颊神经节和视叶中发现的浓度最高。

  4. 给予利血平后,章鱼神经组织中儿茶酚胺和5-羟色胺的浓度显著降低。

  5. 这些发现表明,多巴胺、去甲肾上腺素和5-羟色胺可能作为头足类软体动物的神经递质发挥作用。
