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

Steps to reproduce
Data was created by running it through Lesion Quantification Toolkit (Griffis et al., 2021). Both lesion disconnection maps as well as parcel-disconnections were analyzed in Niistat using Freedman-Lane, with Multiplication as a dependent variable and lesion size and number reading skills as covariates. Further files are provided to reproduce visualization as in the paper.
