General Information

Term

femoral chordotonal hook neuron

ID (Ontology)

FBbt:00049558 (Fly Anatomy)

Definition

Femoral chordotonal organ (FeCO) neuron with a projection that follows the dorsal branch of the claw neurons and also has a medial projection, which turns slightly posteriorly (Mamiya et al., 2018). Its soma is found in a small cluster along the ventral edge of the FeCO (Mamiya et al., 2018). It encodes sensory information about directional tibial movement (Agrawal et al., 2020).[ FlyBase:FBrf0240598 FlyBase:FBrf0247582 ]

Also Known As

"FeCO hook neuron"
