Banino et al.'s approach paves the way also to a potential approach towards a better comprehension of our "second brain", i.e., the myenteric plexus. We know that enthorinal grid cells are placed in exagons and fire when a moving animal crosses their firing fields. If we examine flat mounts of whole gut slices, we find the same nervous exagonal grid, which is located preferentially in the myenteric plexus. Therefore, a theoretical, testable hypotesis can be drawn: the same topological exagonal scheme found in the enthorinal regions might enable myenteric neurons to recognize the location of food volumes or chemical substances in the gastroenteric lumen, enabling our gut to "recognize" the location of its own content. We could, therefore, be in front of an "intestinal map", based on the same mechanisms of external environment's enthorinal recognition.
