Question

Which retinal ganglion cell will respond with the most action potentials?

Choose one

Group of answer choices an on-center cell receiving a large amount of ambient (diffuse) illumination

an off-center cell whose centre is brightly illuminated

an off-center cell whose surround region is brightly illuminated

an on-center cell with a shadow edge falling across its diameter

The existence of more than 30 distinct brain regions devoted to analyzing information transmitted from the retina suggests

Group of answer choices

that various features at the information contained in the retinal image may be analyzed in dedicated modules

anatomists are probably overzealous scientists

that little image compression occurs at early stages of visual processing

the concept of "trigger features" is questionable

Answer 1

Answer for 1-

An on -centre cell receiving a large amount of ambient (diffuse) illumination.

Explanation -ON centre or Off surrounding  - striking the bright spot at the centre receptive field subregion increase the cell response where as flashing bright annulus in surrounding receptive subregions inhibits the cell's response.

off centre or on surrounding gangalion cell have different response than above condition , it shows inhibition from small spot of light in centre and shows excitation response from annulus in surrounding.
