Anatomy Term : FBbt:00004223 photoreceptor cell R6 Fly Anatomy

Namespace  fly_anatomy.ontology Obsolete  false
description  Outer photoreceptor cell of the adult eye whose rhabdomere is located at the right angle vertex of the shorter of the two parallel sides of the trapezoid of rhabdomeres in each ommatidium. It has a single axon that projects along a single lamina optic cartridge (Fischbach and Dittrich, 1989; Wolff and Ready, 1993) within which it makes extensive presynaptic connections with the lamina monopolar cells L1-L4 (L4 collaterals from adjacent columns) and lamina intrinsic (amacrine) cells, before terminating in the proximal lamina. It also establishes connections with epithelial and marginal glial cells. The photoreceptor R6 receives input from L4 (L4 collaterals from adjacent columns) and lamina wide-field neurons Lawf (Rivera-Alba et al., 2011).

FBbt:00006009 eye photoreceptor cell 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).

FBbt:00003718 lamina monopolar neuron A monopolar, intrinsic columnar neuron whose cell body lies in the cortex of the lamina and that has a single major projection that projects along a single lamina optic cartridge, crosses the first optic chiasm and terminates in the equivalent column of the medulla.
FBbt:00003627 protocerebrum The most anterior of the segmental subdivisions of the insect CNS; thought to represent the first pre-oral segment of the brain. The protocerebrum comprises many discrete neuropil regions including the central body complex and mushroom bodies.
