(FRAME-INFO (STRING "Retinal Ganglion Cells. \(Image compliments of Dr. D. Dacey, Dept. of Biological Structure, University of Washington\). Photograph of two HRP-filled ganglion cells in human retina close to the fovea. On the left is a parasol cell, a large ganglion cell type with high contrast sensitivity that projects to the magnocellular part of the lateral geniculate nucleus. Parasol cells are responsible for detecting luminance contrast. On the right is a midget cell, with an extremely small dendritic field \(the little tuft at its upper extremity\). Midget cells project to the parvocellular part of the lateral geniculate nucleus and are responsible for high acuity and color vision."))
