格伦德费斯特在很长一段时间里都保持着电火花派身份，甚至在埃克尔斯和其他大多数神经生理学家都已经确信了突触传递的化学本质之后。直到1954年9月，我进入他实验室之前一年，格伦德费斯特才在一本重要的关于神经冲动的专题论文集中转变了看法。他写道：“埃克尔斯最近已经接受了这种（神经细胞到神经细胞的）传递是化学介导的观点。我们中有些人反对这一观点。……我们可能是错误的。”（D. Nachmansohn and H. H. Merrit, eds., Nerve Impulses; Transactions[New York: Josiah Macy Jr. Foundation, 1956], 第184页。）
