y cell造句

• He discovered that the Y cell collected excitatory signals from many small spatial mechanisms called  nonlinear subunits and that there was a contrast gain control, a nonlinear feedback within the retina that adjusted the signal-transfer properties of the retina contingent on the space-averaged stimulus contrast.
• Cells showing linear spatial summation are termed X cells ( also called parvocellular, P, or midget ganglion cells ), and those showing non-linear summation are Y cells ( also called magnocellular, M, or parasol retinal ganglion cells ), although the correspondence between X and Y cells ( in the cat retina ) and P and M cells ( in the primate retina ) is not as simple as it once seemed.
