this study suggests that neurons of the medullary raphe may be influenced by communication channels including dendro-dendritic contacts within the midline bundle , fourth ventricular cerebrospinal fluid-borne influences through tanycyte shafts , blood-borne influences through the direct neuronal-vascular relationship in the raphe , and traditionally described axonal contacts impinging upon raphe neurons .
