Dyslexia, Rhythm, Language and the Developing Brain
Recent insights from auditory neuroscience provide a new perspective on how the brain encodes speech. Using these recent insights, I will provide an overview of key factors underpinning individual differences in children’s development of language and phonology, providing a context for exploring atypical reading development (dyslexia). Children with dyslexia are relatively insensitive to acoustic cues related to speech rhythm patterns. This lack of rhythmic sensitivity is related to the atypical neural encoding of rhythm patterns in speech by the brain. I will describe our recent data from infants as well as children, demonstrating developmental continuity in the key neural variables.
Neural systems for vocal perception
For social animals, successfully communicating with others is essential for interactions and survival. My research aims to answer a central question on the neuronal basis of this ability, from the perspective of the listener: how do our brains enable us to communicate with each other? My work develops nonhuman animal models to study the behavioural and neuronal mechanisms underlying the perception of vocal patterns. I will start by providing an overview of my past research characterizing the neuronal-level substrates of voice processing along the primate temporal lobe. I will then focus on my current work on vocal perception in mice, in which I utilize natural male-female courtship behaviour to evaluate the acoustic dimensions extracted by listeners from ultrasonic sequences. I will then talk about ongoing work investigating the neuronal substrates supporting the perception of behaviourally relevant acoustic cues from mouse vocal sequences.
