We are investigating cortical re-organization in adults and children with hearing loss who are fitted with hearing aids and cochlear implants using EEG and behavioral paradigms.

• Central Auditory Maturation in Children with Cochlear Implants: We are examining sensitive periods for cortical maturation using cortical auditory evoked potentials, high-density EEG using time and frequency domain electrophysiologic analyses.
  • For more information about cochlear implants please visit the National Institute on Deafness and Other Communication Disorders website

 

• Central Auditory development in hearing impaired children who receive intervention: We are evaluating the efficacy of cortical auditory evoked potentials to validate interventions (such as hearing aids and cochlear implants) in infants and young children with hearing loss.

• Cross-modal Cortical Re-organization in Hearing Impairment: Using high density EEG, we are examining how different sensory systems (e.g., visual and auditory) in the brain interact and change when normal auditory input has been altered.

• The influence of dys-synchrony on Cortical Development in children with Auditory Neuropathy Spectrum Disorder (ANSD): Ongoing research in our lab focuses on how dys-synchronous neural activity alters the auditory cortical maturation and behavioral outcomes in infants and children with ANSD. We are also developing objective, electrophysiologic techniques for guiding intervention with hearing aids and cochlear implants in children with ANSD.

• EEG correlates of cognitive auditory processing: We are developing innovative auditory and visual paradigms to examine correlates of cognitive processing in adults and children with auditory processing difficulties.

Lab Equipment

What we use to do the job

Our main lab is equipped with two state of the art research EEG systems: 1) Compumedics Neuroscan Synamps II, which allows individual channel EEG recordings as well as high density EEG (up to 128 channels); and 2) Electrogeodesics (EGI) 128 channel high ensity EEG system. Testing is carried out as our participants and patients sit comfortably in a double-walled sound suite equipped with a large flat pannel monitor, high grade speakers, supra aural headphones, insert earphones, and bone oscillator.

(pictures coming soon)

The lab also houses several workstations for use by students for data processing and analysis.

(pictures coming soon)

In addition, because our lab is focused on pediatirc research, we have plenty of movies, toys, and activities for children to use.
