Differentiate between divergent and convergent neural circuits
A) In divergent circuits, information spreads from one neuron to several neurons. In convergent circuits, several neurons synapse with one postsynaptic neuron. B) In divergent circuits, several neurons synapse with one postsynaptic neuron. In convergent circuits, information spreads from one neuron to several neurons. C) In divergent circuits, information from one neuron is spread through one hemisphere of the cerebrum. In convergent circuits, information from one neuron is spread through both cerebral hemispheres. D) In divergent circuits, information from one neuron is spread through both cerebral hemispheres. In convergent circuits, information from one neuron is spread through one hemisphere of the cerebrum. E) In divergent circuits, branches of axons somewhere along on the circuit extend back toward the source and stimulate the presynaptic neuron similar to a positive feedback loop. In a convergent circuit, the original presynaptic neuron is not stimulated by axons further down the circuit.
