  "account": "Vocal communication relies on the structural integrity of the vocal folds, but the consequences of injury on vocal behavior are not fully understood. A study using California mice, a species known for its vocal songs, explored how targeted vocal fold injury affects production. By analyzing recordings over time and examining tissue changes via histology, researchers observed an acute swelling in the vocal fold structures. Despite keeping vocal activity levels constant, the injury led to a noticeable change in the vocal pattern. This suggests that vocal behavior can continue even when there are significant alterations to the tissues responsible for sound production, indicating that the ability to communicate does not always reflect the health of the underlying system. The findings offer a new way to study how injuries and tissue changes can modify vocal communication, with implications for broader understanding of how vocal use, injury, and recovery affect acoustic signals.",
  "summary": "Vocal communication depends on the biomechanical integrity of the vocal folds, yet how impairment alters vocal behavior remains poorly understood. We used the California mouse (Peromyscus californicus), a highly vocal species that produces songs through airflow-induced vocal fold vibration, to experimentally examine how defined vocal fold injury alters vocal production. Longitudinal recordings…",
