title: [The paracommissural regions (brain neurohemal formations) of diplopods. Preliminary note].
abstract: The paracommissural plates of Diplopods are neurohemal "organs" anatomically not individualized in bodies separate from the brain. They lie near the transverse commissure (tritocerebral commissure s.l.). They are composed of at least two distinct types of axon terminals, glial cells, tracheae and a neural lamella facing a blood sinus. The axons of paracommissural plates of originate in neurosecretory cells lying in the ganglions of the transverse commissure. The release of granules partly occurs by exocytosis.
