Color Vision in Sky vs Ground: Neurons and Diversity of Brain Cells
A Found Poem made up of words already on the page, selected out and highlighted by the poet.
Brains exhibit / neurons achieve diversity / turning on process
―Science Haikus and Found Poetry
Atlas of 250,000 neurons in brains of fruit flies
exhibit most
molecular diversity during development
published in Nature reveals
neurons achieve diversity
by turning on
different sets of genes
60,000 cells and 200 neuronal types
fruit flies’ optic lobes process
visual information, color vision
detection of objects and motion
Neuronal diversity serve
a paradigm to understand
brain development across species
a completely new neuron removed
through programmed cell death
right before the flies’ hatch
called Cajal-Retzius cells
also exist in mammalian brains
Disruptions due to defects in genetic programs
only transiently active during development
impossible to understand by simply looking
at the end result ability to perform
different calculations on visual information
for instance, sky versus the ground.
