Math format invariance data & code

Here we provide preprocessed fMRI data and analysis scripts used in "Quantitative modeling demonstrates format-invariant representations of mathematical problems in the brain” The preprocessed data are provided for each participant (sub-01 to sub-08). The analysis scripts require MATLAB (R2019b) and FreeSurfer. Ridge regression <pre><code>ID = 'sub-01'; Method = 'Operator'; Code = 1; %1: all operators %2: only single operators %3: only double operators Ridge(ID, Method, Code) Ridge_CrossModal(ID, Method, Code)</code></pre> Modality invariance and modality specificity <pre><code>ModInv(ID, Method, Code) ModInv_MinusRead(ID, Method, Code) ModSpec(ID, Method, Code)</code></pre> Representational similarity analysis RSM_Group_WholeCortex(Method, Code) <pre><code>RSM_Group_WholeCortex(Method, Code) RSM_Group_WholeCortex_MinusRead(Method, Code)</code></pre> Principal component analysis <pre><code>PCA_Group_WholeCortex(Method, Code)</code></pre> If you have any questions, please send an email to nakai.tomoya [at] neuro.mimoza.jp.
