↵F1-a Each number represents a separate chimera. R, Right hemisphere; L, left hemisphere.
-
↵F1-b Interneuron percentages are based on direct counts versus estimates for pyramidal and granule cell populations. Only chimeras with the lowest-percentage chimerism of interneuron populations were counted.
-
↵* indicates not counted.
