A camera is a passive recorder of the world, but the visual systems of mammals build up pictures of the world by detecting its meaningful features
Integrate the research on the visual system with information that was presented in Chapter 4 regarding the thalamus and the visual cortex.
What will be an ideal response?
Answer: A good answer will include the following key points.
• After the ganglion cells receive input from the bipolar cells, their axons, which form the optic nerve, carry the information to the brain.
• The thalamus, roughly in the center of the brain, directs sensory input to higher areas. For vision, for example, the thalamus sends the input on to the occipital lobes.
• The occipital lobes contain the visual cortex where visual signals are processed.
• This is where Hubel and Wiesel found feature-detector cells.
• Damage to the occipital lobes can impair visual recognition or even cause blindness.
