Abstract

Eighty visual units were extracellularly recorded from the pigeon optic tectum, and the effects of iontophoretically applied acetylcholine and its antagonists, atropine and tubocurarine, on these units were examined. The results showed that acetylcholine in the avian tectum functions as an excitatory transmitter or modulator and acts predominantly through a muscarinic mode of action.

摘要

从鸽子视顶盖细胞外记录了80个视觉单位，并研究了离子电泳施加乙酰胆碱及其拮抗剂阿托品和筒箭毒碱对这些单位的影响。结果表明，鸟类顶盖中的乙酰胆碱作为一种兴奋性递质或调节剂起作用，主要通过毒蕈碱作用模式发挥作用。
