Previous research has shown a relationship between robust neural encoding of speech by the auditory brainstem and children's phonological abilities. Two areas of brainstem encoding this work has included are the ABR dimensions of consistency, or how similar responses are to a repeated stimulus, and differentiation, or the degree to which responses…

Stuttering is a developmental speech disorder characterized by interruptions of fluency. A large body of research suggests that stuttering occurs due to a reduced ability to generate timing signals in order to sequence speech sounds. One piece of supporting evidence for this is that when speaking along with an external timing source like a…

Models of speech perception suggest a dorsal stream connecting the temporal and inferior parietal lobe with the inferior frontal gyrus. This stream is thought to involve an auditory motor loop that translates acoustic information into motor/articulatory commands and is further influenced by decision making processes that involve maintenance of…

Short term synaptic plasticity is a phenomenon which is commonly found in the central nervous system. It could contribute to functions of signal processing namely, temporal integration and coincidence detection by modulating the input synaptic strength. This dissertation has two parts. First, we study the effects of short term synaptic plasticity…
