How is it co-opted by and coordinated with other behaviors?

Breathing is such a fundamental, innate behavior. Yet, we also have the amazing capacity to immediately stop or alter it, like when we speak, cry, swallow, or hold our breath and even the type of breath we take can be regulated by our emotions, like a “sigh of relief”. This is in stark contrast to the body’s other key rhythm, our heartbeat. To understand how this occurs, we have focused our efforts towards understanding how innate vocalizations, like neonatal cries, are timed and coordinated with the breath.
