Vision - The human eye - Processing of light
4 important questions on Vision - The human eye - Processing of light
How is light modified before it reaches the retina?
- Puil limits the amount of light entering the eye
- The lighte is focussed by the lens.
In what steps is light processed?
- Light hits the retina in one eye and activates a reflex
- Signal to the optic nerve, to thalamus, to midbrain
- Then neurons constrict the pupils.
Whatare the five type of neurons in the retinal layer in the retine of the eye?
- Photoreceptors
- Bipolar cells
- Ganglion cells
- Amacrine cells
- Horizontal cells
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
