HBeyelet [FBbt_00005740]

Cholinergic, rhabdomeric photoreceptor cell of the eyelet (Yasuyama and Meinertzhagen, 1999). It expresses Rh6 and is green light-sensitive (Jean-Guillaume and Kumar, 2022). It develops from an Rh5 photoreceptor of the larval Bolwig organ, which changes its Rhodopsin expression during pupal development (Jean-Guillaume and Kumar, 2022). Its functions in the entrainment of the circadian clock (Helfrich-Forster et al., 2002). Its axon terminates in the accessory medulla (Helfrich-Forster et al., 2007). There are four of these cells per eyelet (Jean-Guillaume and Kumar, 2022).

Cholinergic, rhabdomeric photoreceptor cell of the eyelet (Yasuyama and Meinertzhagen, 1999). It expresses Rh6 and is green light-sensitive (Jean-Guillaume and Kumar, 2022). It develops from an Rh5 photoreceptor of the larval Bolwig organ, which changes its Rhodopsin expression during pupal development (Jean-Guillaume and Kumar, 2022).

There are four of these cells per eyelet (Jean-Guillaume and Kumar, 2022).

Evidence that this is a cholinergic sensory neuron comes from staining for choline acetyltransferase expression. (Yasuyama and Meinertzhagen, 1999).
