Infant Auditory Processing and Event-related Brain Oscillations

DOI: 10.3791/52420-v
What you'll learn
  • ✓ Apply high-density EEG netting procedures to infant subjects
  • ✓ Process and analyze event-related brain oscillations from raw EEG data
  • ✓ Interpret oscillatory dynamics during rapid auditory processing in infants
Protocol

High-density electroencephalography (dEEG) is being used increasingly to study brain development and plasticity in the early years of life. Here we present an application of sophisticated analysis techniques that builds on traditional EEG recording to understand the oscillatory dynamics of rapid auditory processing in the infant brain.

Difficulty
advanced
Total time
~1–2 hours per infant session (net application, recording, initial setup)

Steps

1
Apply infant EEG net and initiate recording

Position and secure high-density EEG electrode net on infant subject and establish baseline EEG recording while presenting auditory stimuli.

2
Process raw EEG data and extract oscillations

Apply filtering, artifact removal, and time-frequency analysis techniques to raw EEG recordings to isolate event-related brain oscillations.

3
Analyze and visualize event-related oscillatory responses

Quantify frequency-specific power changes and oscillatory dynamics during auditory processing epochs to characterize infant brain responses.
