General Information
Term larval Basin-4 neuron ID (Ontology) FBbt:00111230 (Fly Anatomy)
Definition Larval basin neuron with ventral dendrites that extend to, and may cross, the midline (Ohyama et al., 2015). It has a relatively dorsal axon position, compared to Basins 1 and 2 (Ohyama et al., 2015). It receives substantial input from multidendritic class IV neurons and does not have presynaptic sites on its dendritic arbor (Ohyama et al., 2015). It is involved in the larval behavioral response to nociceptive stimuli (Ohyama et al., 2015).[ FlyBase:FBrf0228257 FlyBase:FBrf0233796 FlyBase:FBrf0254149 ]
Also Known As "larval A09c neuron"
Comment Authors of FBrf0228257 and FBrf0233796 do not explicitly state which VNC segments this neuron exists in, therefore, subclasses may not be exhaustive.
