What does divergence mean in neural signaling?

• A. Nerve signals send out information to multiple places
• B. Nerve signals converge onto a single nucleus
• C. Signals travel only within a single neuron
• D. Signals are blocked at interneurons

Answer: (A)

Divergence in neural signaling is when a single neuron sends its output to multiple targets, so one signal can influence several downstream neurons or brain regions at once. This broad distribution allows information to reach different parts of a circuit simultaneously, coordinating diverse responses or activities. The phrasing that captures this idea is one nerve signal spreading to multiple places. In contrast, convergence is many inputs onto one neuron, signaling within a single neuron stays contained, and interneuron gating describes modulation or blocking rather than spreading signals.
