Question

What is the relationship between the cortical areas and the visual field with regards to retinotopic mapping?

• A. There is a one to one mapping for each receptor maps to one neuron in PVC.
• B. The visual field is reversed and upside down on the cortex
• C. The smallest part of the visual field (the fovea) has relatively the largest representation on the cortex
• D. A & C
• E. B & C

Answer 1

Ans:- e) B and C are correct.

• B. The visual field is reversed and upside down on the cortex
• C. The smallest part of the visual field (the fovea) has relatively the largest representation on the cortex

concept:- a small area of retina know as fovea have highest visual acutiy and have max conc of cones. Due to which this area have highest represention on the visual cortex.

retina receives light in a reversed manner that is upside down . It is then oriented in a upright manner in the cortex.
