Synaptic plasticity: one STEP at a time.

abstract：:Amyotrophic lateral sclerosis (ALS) is a lethal disease that is characterized by the relentless death of motoneurons. Mutations to Cu-Zn superoxide dismutase (SOD), though occurring in just 2-3% of individuals with ALS, remain the only proven cause of the disease. These mutations structurally weaken SOD, which indirec...
