The influence of bath application of taurine (1-10 X 10(-4) mol/l) on the activity of motoneurons was studied in the isolated lamprey spinal cord. EPSPs evoked by stimulation of the descending tract as well as unitary EPSPs evoked by intracellular depolarization of the individual Müller axons were depressed, whereas conduction of action potentials in the Müller axons and antidromic action potentials of motoneurons were practically unchanged. A deep depression of electrical, in addition to chemical, components of EPSPs and comparison of the obtained results with the available morphological data on the structure of reticulomotor synapses in lamprey, allow concluding that the inhibitory synapses can be located near the excitatory ones on the motoneuron dendrites.
在离体七鳃鳗脊髓中研究了浴缸应用牛磺酸（1 - 10×10⁻⁴mol/L）对运动神经元活性的影响。刺激下行束诱发的兴奋性突触后电位（EPSPs）以及单个米勒轴突细胞内去极化诱发的单一EPSPs均受到抑制，而米勒轴突中动作电位的传导以及运动神经元的逆向动作电位实际上未发生变化。EPSPs的电成分以及化学成分的深度抑制，再加上将所得结果与七鳃鳗网状运动突触结构的现有形态学数据进行比较，得出结论：抑制性突触可能位于运动神经元树突上兴奋性突触的附近。
