The scotopic system is sensitive due to the convergence of many rods onto each ganglion cell, allowing for spatial summation and an additive effect from weak stimulations.
Le système scotopique est sensible en raison de la convergence de nombreux bâtonnets sur chaque cellule ganglionnaire, permettant une sommation spatiale et un effet additif des faibles stimulations.
| Front | Explain why the scotopic system is sensitive? |
|---|---|
| Back | 1. Many bipolar cells converge on each ganglion cell 2. Results in high degree of spatial summation 3. Weak stimulaiton of many rods can produce additive effect on one bipolar cell; several bipolar cells can act together to stimulate one ganglion cell |
