"Dr. Swaroop summarized the biology of photoreceptors. In humans, rods outnumber cones 20:1 (106 million rods to 5-6 million cones). Photoreceptors are highly metabolically active, with the outer segments regenerated every 10 days. Stringent control of differentiation and homeostasis isrequired for functional maintenance, and dysfunction or death of photoreceptors leads to vision loss. Rods degenerate and die first; cones are like queen bees and rods are like the soldiers. Rods and cones descend along lineages from shared retinal neuroepithelial progenitor cells"
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
