Which of the following is not typically associated with EEG waveforms seen in infants?

In the context of EEG waveforms observed in infants, alpha waves are typically not present. Alpha waves are associated with relaxed, awake states in older children and adults, generally emerging around the age of 5 to 7 years. In infants, the predominant waveforms include delta and theta waves, which are part of the normal developmental EEG pattern. Delta waves are prominent during deep sleep, while theta waves are seen during drowsiness and light sleep.

Beta waves occur in more alert states and tend to appear later in neurological development, becoming more prominent as children grow older. The presence of alpha waves is tied to a specific developmental stage that infants have not yet reached, underscoring why alpha waves are not typically associated with their EEG patterns.
