How do posterior slow waves of youth behave when adolescents open their eyes?

When adolescents open their eyes, posterior slow waves, often referred to as posterior dominant rhythm or alpha waves, typically attenuate. This attenuation occurs because the act of opening the eyes is associated with increased alertness and a shift in brain activity. In a resting state with closed eyes, alpha waves are more prominent, reflecting a relaxed state of wakefulness. However, as the individual becomes more engaged or attentive, as happens when their eyes are opened, alpha wave activity generally decreases. This change is a normal physiological response indicating a transition from a more passive state to an active state of awareness and cognitive processing. Therefore, the behavior of posterior slow waves during this transition reflects the brain’s adaptability to varying levels of sensory input and arousal.
