Electromyographic features of MCK-UCP1 mice.

<p>A: representative electromyography recordings in gastrocnemius from a 7-month-old wild-type mouse (left panel), and two 7-month-old MCK-UCP1 mice showing weak (middle panel) and intense (right panel) altered electrical activity. B: fraction of mice presenting with aberrant spontaneous denervation activity in at least one muscle territory. Wild-type mice (empty triangles), MCK-UCP1 mice (filled triangles) (n = 6–10 mice per group). C: decrement observed in a repetitive stimulation test in gastrocnemius from 7-month-old wild-type (Wt) and MCK-UCP1 mice (n = 6 mice per group). D: sensory nerve velocity in 7-month-old wild-type (Wt) and MCK-UCP1 mice (n = 6 mice per group).
