New paper published:Neural responses to naturalistic audiovisual speech are related to listening demand in cochlear implant users-- Nov 8, 2022

In this study we used The Office TV show as a stimulus in cochlear implant users. We showed that brain responses using this "naturalistic stimulus" relates to listening demand.

New paper published:Evidence of visual crossmodal reorganization positively relates to speech outcomes in cochlear implant users-- Nov 1, 2022

In this study we show that crossmodal plasticity is positively related to speech perception in noise in cochlear implant users.

New paper published:Objective and Subjective Hearing Difficulties Are Associated With Lower Inhibitory Control-- May 9, 2022

Congrats to Bowen and Priyanka who have successfully defended thier MSC thesis': December 8, 2021

COVID-19 update: June 8, 2020

We have temporarily ceased all testing in the physical lab until further details are avalible. However, we have been busy developing online testing material. Stay tuned!

We are hosting Dr. Carles Escera--Sept 28, 2018

We will be hosting Professor Carles Escera on Monday October 1st for a presentation:
Neurocognitive mechanisms in audition as revealed with the Frequency-Following Response
4:00-5:00pm
Room E115
Carles Escera is a full professor at the University of Barcelona who research focus is auditory attention, perception, memory and executive function using EEG in various neurological, neurodevelopemental, and psychiatric disorders. Click here for his website

Dr. Escera will be coming to the Cochlear Implant lab in the ENT clinic earlier in the day. If you'd like to meet him please contact me.
