During active sleep, what is typically observed in a full-term neonate?

During active sleep in a full-term neonate, it is common to observe irregular respirations and rapid eye movements (REM). This state is characterized by bursts of activity and is crucial for brain development. The presence of eye movements indicates that the neonate is experiencing active dreaming or processing of information, which is essential during this early stage of life. Additionally, the irregularity in respiration rates reflects the neural immaturity of the infant and is typical during this sleep phase, as the autonomic nervous system continues to develop and stabilize.
