Hey, everyone. Let's take a look at this question together when a single presynaptic neuron synapses with multiple post synaptic neurons allowing for signal amplification and the spread of information to multiple pathways. It is called, what is it? Answer choice. A parallel fiber system. Answer choice B converging circuit, answer choice C reverberating circuit or answer choice D diverging circuit. Let's work this problem out together to try to figure out which of the following answer choices best explains when a single presynaptic neuron synapses with multiple post synaptic neurons. So in order to solve this question, we have to recall what we know about when we have a single presynaptic neuron that synapses with multiple post synaptic neurons allowing for signal amplification and the spread of information to multiple pathways. So we have that single presynaptic neuron that synapses with multiple postsynaptic neurons. And we can say we have our single presynaptic neuron that synapses with a postsynaptic neuron. And then another post tic neuron and another post synaptic neuron where we can identify that at this point that synapse from the single presynaptic neuron diverges from the pathway into multiple postsynaptic neurons, which is referred to as a diverging circuit. So answer choice D diverging circuit is the correct answer. Since a diverging circuit involves that single presynaptic neuron synapses with multiple postsynaptic neurons allowing for that spread of information to multiple pathways. So answer choice D is the only correct answer choice. I hope you found this video to be helpful. Thank you and goodbye.
