During EEG monitoring, what typically happens to the amplitude of the background rhythm in children as they develop?

As children develop, the amplitude of the background rhythm in their EEG typically increases. This phenomenon reflects a maturation process in the brain as neural connectivity improves and more synchronized cortical activity occurs. In early childhood, the EEG patterns often show more variability and lower amplitudes due to the ongoing development of the brain and its various synaptic connections. As maturation progresses, the organization of neural networks becomes more efficient, leading to increased amplitude in the background rhythms. This increase in amplitude can be particularly observed in frequency bands associated with higher cognitive functions and overall cortical activity. Such changes in EEG patterns are essential in assessing normal brain development and identifying any potential abnormalities.
