Characteristics of ALS donors and extraocular (EOM) and limb muscles examined in each donor.

*The donors were numbered according to the order in which they were collected for EOM vs limb studies. For consistency with the previous donor numbers [6], the newly added and earliest donor of limb muscle only was named Da.RS, rectus superior; RL, rectus lateralis; RM, rectus medialis; OS, obliquus superior; VL, vastus lateralis; BB, biceps brachii; TA, tibialis anterior. The total number of samples studied is given in brackets. wt = wild type phenotype.
