Despite initial and outspoken hesitation,1 quantum chaos has established itself as a veritable field of modern research. However, whereas classically chaotic dynamics describes the behavior of trajectories in phase space, quantum chaos refers to the exponentially fast dispersion of information throughout a quantum many-body system.

A common problem encountered in many areas of science occurs when a model of a dynamical system is required, but models based on first-principles are unavailable, inaccurate, or intractable. In these cases, analysis must be developed based on time series data.

In this work, we present a novel method to decipher and interpret the neural activity patterns associated with bird songs during sleep. Our research reveals that thanks to the discovery of vocal muscles’ activity during sleep, we can effectively translate these silent replays of neural activity into synthetic songs. Key to our approach is the utilization of a dynamical systems model for song production.
