title: [Neuro-humoral interrelationships in ontogeny].
abstract: A.A. Ukhtomsky's ideas of the relationship between the electric and the humoral components of transmission of nervous impulses in thr organism, are considered.  The data obtained recently when studying synaptic transmission of excitation in the sympathetic ganglia of mammals during ontogeny are presented in corroboration of A.A. Ukhtomsky's ideas of that the humoral factors affect neural reactions changing the lability of substratum, which is manifested by the grade of polarization of cellular membrane to a certain critical extent.
