phenotype observed in females
phenotype observed in males
N normal phenotype
nervous system
• marked decrease in the rhythmicity of spinal cord locomotor like outputs and increase in the variance of flexor related bursts between the left and right halves in the presence of allatostatin

behavior/neurological
• after application of allatostatin to the L2 - L4 segments 5 of 8 mice showed profound changes in their gate with changes in the timing and duration of both the stance and swing phases of the gait
• however, in the absence of treatment no gait abnormalities were seen

N normal phenotype
nervous system
• electroneurogram recordings from ventral roots indicates a suppression of synaptic transmission disrupting locomotor rhythm
• outputs from spinal cords show increased variability in the duration of individual motor bursts and in the length of the step cycle period which may be coupled with asymmetry in the duration of flexor bursts between the right and left sides of the spinal cord
• spinal cords show impaired production of locomotor like oscillations following induction with NMDA and 5-hydroxytryptamine or after electrical stimulation of sensory afferents
