neu·ral ret·i·na

(nūr'ăl ret'i-nă)
The optic part of the retina; it contains photoreceptors that are sensitive to visual light rays.


pertaining to a nerve or to the nerves.

neural crest cells
a group of neuroepithelial cells which condenses dorsal to the neural tube in the embryo; they subsequently migrate and set up dorsal root ganglia, the ganglia of the autonomic nervous system, and the pigment cells of the integument (melanocytes).
neural folds
in the embryo, the sides of the invaginated neural plate that meet and fuse over the neural groove to form the neural tube.
neural groove
the longitudinal furrow in the neural plate of the embryo.
neural lymphomatosis
neural plate
the thickened ectoderm dorsal to the notochord in the embryo that gives rise to the neural tube.
neural retina
separated from the outer layer of the optic retina by the intraretinal space; constitutes the pars optica retinae, with its neuroepithelial layer (contains rods and cones—the receptor cells), bipolar ganglion layer, multipolar ganglion layer, and a layer of axons of the latter layer. Light must pass through the latter three layers before reaching the receptor cells.
neural substrates
functional units of the central nervous system, often composed of a series of structural units which may be widely separated anatomically but which interact to support or drive complex nervous system functions, such as hunger and sleepiness. They are the counterparts of simple centers, e.g. the respiratory center, which control simple physiological mechanisms.
neural tropic influence
the tropic influence of nerves on, for example, muscle, demonstrated by the atrophy of muscle when it is denervated.
neural tube
the precursor of the central nervous system in the embryo, formed by invagination and fusion of the neural plate.

1982) found that the presence of the neural retina was key to inducing lens regeneration during larval stages.
36) The basic structure of the vertebrate neural retina consists of two synaptic layers (outer and inner plexiform layers) sandwiched between three cellular layers (outer and inner nuclear layers and the ganglion cell layer).
Its development begins with the formation of the optic vesicle, a pocket of epithelium that deepens and pinches to form the optic cup, which develops a double layer of cells, with pigment epithelium on the outer, and neural retina on the inner wall.
The RPE cells also absorb light and prevent incident light being reflected back to the neural retina, which result in loss of image sharpness.
