Fei Peng


Fei Peng's main research interest is the neural coding mechanisms of natural sounds, such as voice pitch of Mandarin tones and statistics in the textures. She has explored the neural coding of the time-varying pitch contours in Mandarin tones in the inferior colliculus of the guinea pig at Chongqing University, China; and investigated the auditory brainstem and cortex responding to the resolved and unresolved harmonics of Mandarin tones by measuring human EEG at Bionics Institute, Melbourne.

She is currently funded by the Research Grants Council Hong Kong, and to explore the neurons in the key stages of the ascending auditory pathway, including the inferior colliculus, primary and secondary auditory cortex of rats to synthetic auditory textures sounds with systematically varying statistics, presented in isolation and superposition.
