Arithmetic fact retrieval deficits in chronic stroke – a deficit of relearning?

This dataset contains processed lesion data of patients in the chronic phase of stroke (> 6 months) with initial Aphasia. They were tested on Addition, Subtraction and Multiplication, but only Multiplication was analysed using Lesion Behaviour Mapping. See "how to reproduce" for more details on the analysis. Results suggest that a multiplication deficit in the chronic phase of stroke stems from a deficit of arithmetic re-learning, as lesion behaviour mapping indicated mostly parahippocampal areas involved in (re-)learning.

Version 2 contains an additional README.txt file.
