General Information

Term

serotonergic IP1 neuron 1

ID (Ontology)

FBbt:00110938 (Fly Anatomy)

Definition

Serotonergic IP neuron whose cell body is located anteriorly to the dorsal basolateral protocerebrum. A primary neurite projects to and innervates the antennal lobe. Another process projects dorsally to innervate the lateral and medial region of the posterior brain, including the region around the mushroom body. A single neurite crosses the midline and arborizes in the contralateral antennal lobe.[ FlyBase:FBrf0048551 FlyBase:FBrf0205432 FlyBase:FBrf0219731 ]

Also Known As

"contralaterally innervating serotonin immunoreactive deutocerebral interneuron" ; "CSD" ; "CSD interneuron" (for all, see Synonyms field below)
