part of has soma location supraesophageal ganglion neuron adult brain adult DN period neuron Kaneko et al. (1997) suggest that the larval DN period neurons could be the same cells as the adult DN period neurons based on position of the soma. However, they further comment that these cells do not continuously express Period (FBgn0003068) throughout the developmental stages, making developmental profiling difficult. Furthermore, antiphase cycling of Period observed in larval DN period neuron-2 was not found in either the pupal or adult DN period neuron-2, suggesting that these cells would have to change their Period cycling phase during metamorphosis if they are the same cells. Because of this uncertainty, this ontology does not currently record a developmental relationship between the larval and adult DN neurons.
