Neuromuscular junctions in homozygous third instar larvae show a complete lack of synaptic homeostasis after treatment with philanthotoxin-433 (PhTX): the average EPSP amplitude is significantly reduced in the presence of PhTX compared with the baseline measured in the absence of PhTX.
Neuromuscular junctions in double heterozygous RimMB07541/+ ; Rab3-GAPunspecified/+ third instar larvae do not show significant synaptic compensation after treatment with philanthotoxin-433.
