General Information
Term adult ellipsoid body ring neuron R4m ID (Ontology) FBbt:00007537 (Fly Anatomy)
Definition Ring neuron R4 whose arborization in the ellipsoid body fills most of the ellipsoid body outer central domain, except for the region occupied by R4d terminals (Renn et al., 1999; Omoto et al., 2018). It has dendrites in the anterior bulb (Omoto et al., 2018). It responds to temperature increases and mediates thermoresponsive behavior (Buhl et al., 2021). It activity decreases the amount of nighttime sleep (Yan et al., 2023).[ FlyBase:FBrf0111476 FlyBase:FBrf0210154 FlyBase:FBrf0240929 FlyBase:FBrf0247746 FlyBase:FBrf0255642 ]
Also Known As "ER4m" ; "R4m neuron" ; "ring neuron R4 medial"
Comment This most likely corresponds to the R4 neuron identified by Hanesch et al. (1989) (Omoto et al., 2018).
