nervous system

abnormal nervous system physiology ( J:209344 )

• frequencies of locomotor activity induced in isolated spinal cords increase with increasing NMDA concentrations, but are significantly lower than those observed in control spinal cords

• locomotor burst duration increases but duty cycle is not changed in mutant preparations (increased interburst interval)

• coefficients of variation of main locomotor parameters (cycle period, burst duration, amplitude, duty cycle) are increased compared to controls

• spinal cords from mutants display lower drug-evoked and stimulus-evoked locomotor frequencies

• flexor-extensor coupling is not significantly changed at any locomotor frequency

• Genetic Background: involves: 129S/SvEv * 129S6/SvEvTac * C57BL/6

nervous system

abnormal nervous system physiology ( J:209344 )

• electrical stimulation of spinal cords to induce locomotor activity is decreased by about 25% when Shox2 interneurons are inactivated by light, which is similar to the phenotype observed when the population of Shox2 interneurons is ablated

nervous system

abnormal spinal cord grey matter morphology ( J:209344 )

• number of Shox2-expressing V2a interneurons is reduced by 98%; total number of Shox2-expressing interneurons is reduced by >80%

abnormal nervous system physiology ( J:209344 )

• variability in locomotor parameters (cycle period, burst duration, amplitude) that are observed in isolated neonatal spinal cords exposed to low NMDA concentrations is increased in mutants compared to controls; higher NMDA concentrations reduce this variability

• other parameters such as burst frequency and flexor-extensor alternation are not significantly different
