The callosal dilemma: Explaining diaschisis in the context of hemispheric rivalry via a neural network model by Reggia, James A., Goodall, Sharon M., Shkuro, Yuri, Glezer, Mark

“…It is often suggested that a major factor in diaschisis is the loss of transcallosal excitation to the intact hemisphere from the lesioned one. However, there…”
