Kathy with Grady on March 18.
Grady did something new on Wednesday. While I was feeding him his bottle, he actually turned his head and looked away from me. Seriously, I was a bit shocked at first as we've spent this first month gazing lovingly into each other's eyes as he eats. Then I remembered my friend Chris' research on gender differences for our master's program. Researchers have discovered that boys and girls have different cells in their eyes. Chris' article states, "The ganglion cells in our eyes are of two different types—P and M—each having very different jobs. M-cells, which are larger, are wired to rods and are primarily simple motion detectors. P-cells, which are smaller, are concentrated around the fovea, or the center of the field of vision, and are responsible for collecting information about color and texture.
Only very recent microscopic analysis of the eye has revealed that the retinas of male and female eyes have vastly different concentrations of these cells. Female retinas have a much higher concentration of P-cells (responsible for colors and textures), and male retinas have many more M-cells (responsible for tracking movement). Sax puts it this way. P-cells (denser in females) answer the question, “What is it?” M-cells (denser in males) answer the question, “Where is it going?” The interesting thing is that these are large differences that hold true across species. Every male animal has more M-cells than every female animal." If you're interested in reading more, here's a link to his article and our newest venture We Teach, We Learn: http://www.weteachwelearn.org/2009/05/the-eyes-have-it/I reread Chris' research and felt absolutely relieved. Grady is doing exactly what he is made to do!
