Multiple Choice

Which of the following refers to the photoreceptors responsible for color vision?

• rods

• cones

• bipolar cells

• optic nerves

How do your eyes sense and transform

light energy?

Multiple Choice

Visual information from the retina is relayed from the optic nerve through the _____ to the primary visual cortex, which is located in the occipital lobe.

• amygdala

• hypothalamus

• thalamus

• hippocampus

• cerebellum

How does the brain process

visual information?

(Perception)

1. Feature Detection

Cells in retina & occipital lobe respond to the specific features of a scene (edges, lines, angles) & then pass the information to other brain areas 

2. Parallel Processing

Neural networks process combined info about color, movement, form, depth.

3. Recognition

Brain interprets the constructed image based on info from stored images.
