visual cortex
"The arrangement of the cells in the visual cortex is like a series of maps of the visual fields of the eyes."
"In each of the different areas, adjacent cells receive signals from adjacent areas of the retina, so that each area of the visual cortex is like a map of the retina "
"The visual cortex is like a tiled floor, with each neuron responding to visual stimuli in its own small area. Collectively, the neurons encode all of a visual scene. Each neuron also has a preferred orientation: Some neurons respond best to horizontal edges, others to vertical edges, and still others to oblique ones."
"Rather than lining the skull, as the retina lines the eye, the visual cortex is like a crumpled sheet stuffed into the skull. Each location where the folded cortex forms a ridge visible from the exterior is called a gyrus, while each shallow furrow that separates a pair of gyri is called a sulcus."
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.
