Mean size ± SD of GABA-LIR varicosities in three different fiber types running across the sensory neurons of a VS-3 organ

Length of varicosities [μm]Width of varicosities [μm]
Thick fiber8.5  ± 2.5 (4.7–14.5; n = 29)2.6  ± 0.65 (1.8–3.9; n = 29)
Medium fiber5.0  ± 1.2 (2.7–7.3; n = 27)1.7  ± 0.6 (0.7–3.3; n = 27)
Thin fiber1.7  ± 0.5 (0.7–2.5; n = 25)1.1  ± 0.5 (0.4–2.1; n = 25)
  • Mean values for length and width differ significantly in all three fiber types (one-sided t test; p < 0.001 in each case). Numbers in parentheses, range between extreme individual values and sample size, n.
