eye photoreceptor cell [FBbt_00006009]

Photoreceptor cell that forms the core of each ommatidium in the adult eye. Eight of these photoreceptors are arranged in each ommatidial core, bundled like the staves of a barrel. Each has a photosensitive rhabdomere that projects into the barrel cavity and adjacent supporting membrane, the stalk (Wolff and Ready, 1993). Each extends an axon into the optic lobe. Activation of the photoreceptor by light results in depolarization and in histamine release at the synapses of these axons (Sarthy, 1991).
