Answer:
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).
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<u> information that retinal ganglion cell sends to the brain comes from many photoreceptors</u>.
The other options are not correct because convergence:
<em> A. It does not depend on all the information seen in the visual field.
</em>
<em> C. It does not depend on the sum of the amount of light it receives.
</em>
<em> D. It does not imply the amount of action potentials.
</em>
<em> E. There are no connections with other ganglion cells.</em>
Answer:
Fear is a natural emotion that protects people from harm when they face real and imminent danger. A phobia is an excessive fear or anxiety related to specific objects or situations that are out of proportion to the actual danger they present.
