Short question You are focusing your vision on a grid of 2 by 2 black square (Herman grid). describe the retinal neural circuitry involved in the perception of the grid and its illusion down to the optic nerve.Assume one cone cell per square or empty space. (5 Marks) You are on the last stretch of a rollercoaster, the cart goes downhill, makes a hard turn to the left before braking and stopping for you to get down. Describe which parts of the vestibular system are stimulated, and how they are stimulated during each stage: Downhill Hard turn to the left Braking and stopping Marks)Explanation / Answer
Answer 1
the retina consist complex neural circuitry which converts the graded electrical activity of photoreceptors into action potentials with the help of axons they travel to the brain in the optic nerve.
The visual illusion includes not only the eyes but the optic nerve, which links the eye to the brain; and the primary visual cortex, the area of the brain that processes visual information.
L and M cones, with little or no contribution from the S cones In Hermann grid
Answer 2
semicircular canals are stimulated , it contain fluid in a three round canal present in semicircular . When this fluid moves, it signals to your brain that your head is moving or not ,
Downhill the fluid in your saccule moves. The fluid moves on the hair cells in the saccule, which tell your brain that you are moving down.
Hard turn to left The fluid inside your utricle pushes on the hair cells, which tell your brain that you are moving left
Break and stopping Even when we stop and are eye closed, the fluid moving in this part of your ear tells your brain which way you are going.
