The book is devoted to the main discussion of the nervous system. Whether information about nerve details is connected to each other, or whether it is distributed along single nerve fibers and reaches with great accuracy. The generally accepted model is the neuron theory of Ramon y Cajal. His opponent is the histologist Camillo Golgi. According to the theory of Ramon y Cajal, nerve impulses propagate in one direction with the help of chemical synapses. According to the Golgi theory, nerve stimuli are connected to each other and innervate the organs in batches. Connections occur between fibers with the help of electrical synapses and syncytia. Impulses are able to propagate in different directions. The monograph presents a large number of preparations of neuronists, which are evidence of the opposite reticular theory. A technique is presented that makes it possible to unmask the illustrations of Ramon y Cajal and demonstrate a large number of syncytia on his preparations. The same amount is found in the tangled networks of the gastrointestinal tract ("abdominal brain"). Electrical connections have also been established in other parts of the nervous system. Electrophysiologically, a circular interconnection of electrical synapses, spikes in a circle has been established, and multiple variants of feedback of nerve fibers have been identified. The unified neural and reticular theories are unified.
