(02) Oct 28, Retinal processing & Visual pathways (ag)
Topics addressed in the lecture:
- Major photoreceptor types
- Encoding of spatial information
- Encoding of color information
- Ganglion cell receptive fields
- Luminance adaptation
Examples for question you should be able to answer:
- Explain how the feed-forward connectivity and lateral interaction in the retina leads to on-center ganglion cell receptive fields.
- Define a visual receptive field. How does the receptive field of an off-center retinal ganglion cell look like?
Important concepts:
- ‘Local coding’ vs. ‘coarse coding’
- Center-surround antagonism
- Dynamic range
- Light adaptation
