Polysynaptic reflexes involve synapses on both sides.

Explanation:
Polysynaptic reflexes rely on interneurons, creating multiple synapses along the pathway. These interneurons can be on the same side of the spinal cord or cross to the opposite side via commissural connections. This cross-communication allows the nervous system to coordinate actions across both sides of the body, as seen in reflexes that involve the opposite limb to maintain balance when one limb withdraws. So, polysynaptic reflexes commonly include synapses that involve both sides of the body, making the statement true. For contrast, monosynaptic reflexes involve a direct synapse between a sensory neuron and a motor neuron and are typically confined to the same side without interneuronal cross-talk.
