In the dark, depolarized photoreceptors release neurotransmitters that inhibit bipolar cells, preventing them from stimulating ganglion cells.
Dans l'obscurité, les photorécepteurs dépolarisés libèrent des neurotransmetteurs qui inhibent les cellules bipolaires, les empêchant de stimuler les cellules ganglionnaires.
| Front | How do photoreceptors affect bipolar cells in the dark? |
|---|---|
| Back | 1. Depolarized photoreceptor releases NT onto the bipolar cells (due to Ca influx) that inhibits them from firing; 2. Inhibited bipolar cells are prevented from releasing NT in order to stimulate the ganglion cells |
