Retina is a part of the central nervous system (CNS) responsible for visual perception and processing. The retina is a complex organ and, like the CNS, it is also an immune privilege site, which has a blood retinal barrier (BRB) - the inner BRB formed by tight junctions of the endothelium and the outer BRB form by the retinal pigment epithelium (RPE). Retinal capillaries are covered by pericytes at a ratio of 1:1 with endothelial cell, which is the highest pericyte coverage in the entire vascular system. Retinal neurons are arranged in three distinctive layers - the photoreceptor layer or outer nuclear layer (ONL), which anchors at RPE, the bipolar layer or inner nucler layer (INL), and the ganglion cell layer (GCL).
Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method.
Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
