Which theory states that vocal fold vibration is mainly dependent on neural impulses?

The theory that asserts vocal fold vibration is primarily dependent on neural impulses is the Neurochronaxic theory. This concept emphasizes the role of the nervous system in controlling the timing and pattern of vocal fold vibrations. According to this theory, the rate of vocal fold vibration is directly tied to the neural impulses that stimulate the muscles responsible for opening and closing the vocal folds. These neural impulses dictate when the vocal folds should vibrate, relating the vibratory cycle to the timing of nerve signals from the brain.

In contrast, the other theories provide different perspectives on vocal fold vibration. Myoelastic-Aerodynamic theory focuses on the mechanical properties and the airflow dynamics that contribute to vocal fold vibration, rather than the neural control mechanism. Vibratory theory encompasses various factors, including mechanical and aerodynamic aspects, but does not specifically assert the primacy of neural impulses. Dynamical systems theory looks at the complex interactions within the vocal system as a whole but does not single out neural impulses as the main driving force behind vibration. Understanding these distinctions clarifies why the Neurochronaxic theory is identified as the theory linking vocal fold vibrations to neural impulses.
