Synapses with a cleft with ' thickened' membranes and presynaptic vesicles and mitochondria occur commonly throughout the grey matter of the spinal cord of goldfish, frog and various mammals studied. Such synapses are generally thought to have a chemical mode of transmission. The absence or rare occurrence of presynaptic neurofilaments in fish and frog accounts for the failure to detect boutons by silver methods, and there is no need to postulate morphologically unspecialized synaptic contacts… CONTINUE READING
