All percentages are taken from the total number of cells that met the criteria to have a step tracking response. IA cells, intermediate-aligned cells; GCA cells, go cue-aligned cells; MOA cells, movement onset-aligned cells. Two right columns show percentages of cells that have both a C1 response and are GCA or MOA.
