More than a reflex: How the spine shapes sex

The study found that a specific spinal circuit is involved in both ejaculation and arousal, and integrates sensory inputs to adjust its output based on the animal's internal state. The researchers also discovered that Gal⁺ neurons receive sensory input from the penis and can trigger ejaculation, but their effects are suppressed by brai...
