The effects of denervation and of direct electrical stimulation of denervated muscle upon the acetylcholine receptor (AChR) clusters and acetylcholinesterase (AChE) spots in the fast avian muscle posterior latissimus dorsi have been investigated. Denervation at day 2 after hatching leads to a disappearance of the junctional AChR clusters and to a marked decrease of AChE spots. Direct electrical stimulation of denervated muscle allows the maintenance of AChR clusters and partly prevents the loss of AChE spots. When AChR cluster and post‐synaptic AChE have disappeared in a denervated muscle, muscle activity induced by direct stimulation is unable to induce their accumulation.
