| summary | In the rare case that both eyes fail to develop, there is a complete absence of light input to the visual system at all stages of development. This raises the question of how the brain utilises the cortical and subcortical areas that would usually process visual information. It has been shown in a number of studies that the ‘visual cortex’ of congenitally blind people is used to process ‘high-level’ auditory information such as language. In this talk I will present a series of fMRI studies in which we attempt to understand how auditory information reaches the occipital lobe. Specifically we have addressed the question of whether subcortical visual structures can also be used to convey auditory information using the visual hierarchy. I will also consider briefly how this altered brain function is reflected in auditory performance. From a developmental perspective this work provides significant insight into the extent to which the human brain can reorganise when deprived of input. |
