Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that affects spinal cord motor neurons. Here the authors use induced pluripotent stem cell-derived motor neurons obtained from patients with ALS-linked mutations, and find functional deficits resulting from a progressive decrease in voltage-activated Na+ and K+currents that occur in the absence of cell death.
