What the Frog’s Eye Tells the Frog’s Brain

Location

from a course in Practical Thinking, The Open University

Movement in relation to background—size, darkness of objects
count, the frog’s brain functioning in layers, one part
responding to fixed patterns
of light and shade (features of the pond), while another
notes fast-moving forms (insects the frog eats),
while another part of the brain perceives
slow-moving patterns (larger animals that eat frogs). I understand

this—say, a fly, a pinprick darts
against grass: ganglion fire—motion and speed
in relation to background, not unlike
my neighbor’s cat, ghosting past my patio door,

or the lizards that make their way like smoky die-cuts
across my carpet. Anything catches my eye:
bicyclist, bird of my peripheral
vision. This isn’t

knowledge, something I was taught, that speed
and shadow equal predator or prey—
though the startle response is still there,

that quickening. I’m no better.
