on the basis of these data , the analysis of the unitary epsps evoked in motoneurons of the lamprey and frog by intracellular stimulation of reticulospinal axons and primary afferent fibers and dendrodendritic interaction between motoneurons , a hypothesis is advanced that neurons of similar type may communicate through pure electrical junctions , whereas successive synaptic articulations between different functional groups of neurons are formed by mixed or chemical synapses .
