Topic 4A Module 4: Vision II
Title
1 Module Overview
2 Module objectives
3 Differences in information coding by rods & cones
4 Paths for information flow from receptors (cones) to RGCs: the concept of a Receptive Field
5 Receptive field size determines visual acuity (the ability to tell fine detail)
1. 5.1 Amount of convergence affects visual acuity
2. 5.2 Therefore visual acuity varies across the retina
6 RF structure: Antagonistic effects of the centre & surround allow signalling of light contrasts
1. 6.1 "On" and "Off" Centre receptive fields
2. 6.2 Why have antagonistic Centre and Surround components to the RF?
7 RF wavelength sensitive: coding of wavelength (colour)
8 Summary of visual processes
9 Test your knowledge
