Question

In the visual system, each retinal ganglion cell demonstrates convergence of information because:

A. It takes in all that it sees in its visual field
B. The information it sends to the brain comes from many photoreceptors
C. Each one sums the amount of light it receives
D. Of the number of action potentials it fires
E. Of the connections it has to other retinal ganglion cells

Answer 1

In the visual system, the convergence of information is due to the fact that each cell of the retinal ganglion cell can demonstrate that information it sends to the brain comes from many photoreceptors (option B).

Step-by-step explanation:

The retina is a structure formed by photoreceptors, called cones and rods. The photoreceptors attached to each retinal ganglion cell can form its visual reception field, while the group of ganglion cells that reach a specific area of the brain form the brain cell reception field.

In the visual system, convergence occurs because the receptive field of several photoreceptors reaches a retinal ganglion cell, and a group of ganglion cells reaches a brain cell to form its receptive field, so the information that retinal ganglion cell sends to the brain comes from many photoreceptors.

The other options are not correct because convergence:

A. It does not depend on all the information seen in the visual field.

C. It does not depend on the sum of the amount of light it receives.

D. It does not imply the amount of action potentials.

E. There are no connections with other ganglion cells.
