Considerations on the possible structrual basis of neuronal integrated functions.
Different types of dendro-dendritic and dendro-somatic contacts in several species are described. They are classified in five varieties: (a) parallel dendro-dendritic contacts; (b) crossed dendro-dendritic contacts; (c) perisomatic interdendritic contacts; (d) perivascular interdendritic contacts; (e) dendro-somatic contacts. It is hypothetically postulated, in agreement with other authors, that the structurally differentiated interdendritic and dendro-somatic contacts could act as functional junctions for the electrotonic spread of stimuli between neighbour neuronal elements.
