In Establishing, versus maintaining, brain function: a neurocomputational model of cortical reorganisation after injury to the immature brain, Varier et al develop a neural network model of motor control and then "lesion" it as it is training. I am new to neural networks and really do not even know where to begin in emulating them so that I can investigate this further for myself. Any hints would be appreciated. The details of the model can be found on page 16 of the linked arxiv paper.
