  • Control and agrinΔz/Δz values are the average ± SEM. The values in parentheses indicate the number of animals examined (

  • * p < 0.05,

  • F2-165 p < 0.001). Percentages (%) refer to the increase in the number of motoneurons with respect to the controls.

  • F2-a The control values were 1800 and 2128 hypoglossal motoneurons.
