Dr Bourne’s interest in systems neuroscience led to a fascination with how reliably and capably the brain develops and becomes tightly interconnected to enable the complex behaviours species have evolved to perform. However, development is an area of neuroscience that is often overlooked in terms of defining the substrate and cause of neurological and psychiatric disorders. Therefore, Dr Bourne’s overarching research goal is to probe the neural substrate of certain diseases and conditions through the development lens. A region of the brain that will be part of a significant focus is the pulvinar nuclei of the thalamus, which has expanded in size, complexity,and function throughout mammalian evolution. Therefore, an overarching aim of the Section on Cellular and Cognitive Neurodevelopment is to take a multi-technique approach to explore the development of thalamocortical circuits and their plasticity into adulthood. This approach has the potential to identify the neural underpinnings of disorders, including schizophrenia, autism, and cortical blindness, as well as help us understand how the brain differentially operates at different stages of life.
