Answer:
K-complex
Explanation:
According to my research on EEG charts, I can say that based on the information provided within the question the researcher should be looking for a K-complex on Aaron's EEG's. This is the largest waveform in an EEG and occurs during stage 2 of NREM sleep. According to researchers this is when the brain evaluates not to signal danger and is also aiding sleep-based memory consolidation.
