Does neuroscience mainly or even exclusively relate to students with disabilities of some kind such as dyslexia/dyscalculia?
No. Most cognitive neuroscience research is done with normal persons. The development of fMRI has made it possible to run normal persons in neuroimaging studies and determine the network of neural areas involved in a given task. Since these networks change with development and practice they can provide insight into questions of how normal individuals carry out skills like reading or computing and allow us to explore how various learning procedures modify these networks in normal participants. For example, neuroimaging has shown a number of brain areas involved in skilled reading. We and ask what education method is most effective in altering the activation of these brain areas and how do they influence the time course of this activation? This can be done at various stages of the acquisiton of the skill. It is altogether possible that different forms of learning, all generally effective could have their influence on different parts of the network. This information could be very useful i
