Physiology Which statement concerning sensory neurons or their functional propeies is true? A All sensory fibers are unmyelinated B In spatial summation, increasing signal strength is transmitted by using progressively greater numbers of sensory fibers C Increased stimulus intensity is signaled by a progressive decrease in the receptor potential D Continuous subthreshold stimulation of a pool of sensory neurons results in disfacilitation of those neurons 💡 Explanation Which statement concerning sensory neurons or their functional propeies is true? ✓ Correct Answer: B. In spatial summation, increasing signal strength is transmitted by using progressively greater numbers of sensory fibers
