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 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.
