Question

Convergence in the context of sensory neurons describes: select one:
a. the reason why receptive fields are so small.
b. how one primary sensory receptor neurons synapses with a secondary neuron.
c. how multiple primary sensory neurons synapse on a single secondary neuron.
d. how receptive fields can overlap with one another.

Answer 1

Answer;

C. how multiple primary sensory neurons synapse on a single secondary neuron.

Explanation;

-Convergence play an important role in receptive fields because there is some overlap in field shape, primary sensory neurons can converge onto a single secondary neuron, which allows for summation of multiple stimuli.

- During secondary receptive field multiple primary sensory neurons converge on a single secondary sensory neuron, their individual receptive fields merge. The larger the secondary receptive field the less the discrimination.
