Ataxic gait in Robo3tm1.1Ache/Robo3tm1.1Ache Ptf1atm1.1(cre)Cvw/Ptf1a+ mice
nervous system
|
• severe impairment of the interolivary commissure
|
|
• only about 1/3 of inferior olivary neurons project contralaterally compared to wild-type controls where all neurons project contralaterally
|
behavior/neurological
|
• in an Erasmus ladder test step time and overall walking pattern are severely abnormal
• impairment is more severe than that of Grid2Lc mice
|
|
• decrease in latency to fall of a rotarod
• impairment is more severe than that of Grid2Lc mice

Reduced internuclear commissure in Robo3tm1.1Ache/Robo3tm1.1Ache Egr2tm2(cre)Pch/Egr2+ mice
nervous system
|
• at E11 - E12, a severe reduction of commissural projections in r3 and r5 is seen
• at E15 and in newborns, virtually no axons are found to cross the midline at the level of the abducens nuclei
|
|
• globular bushy cell projections from the anteroventral cochlear nucleus to the principal cells of the median nucleus of the trapezoid body are exclusively ipsilateral
|
behavior/neurological
|
• impairment in horizontal visual vestibuloocular reflex (VVOR) but not in vertical VVOR
|
|
• impairment in horizontal OKR but not in vertical OKR
• defects occur predominantly in the low frequency range
|
|
• impairment in horizontal VOR but not in vertical VOR
• defects in VOR are more predominant at high frequencies
|
hearing/vestibular/ear
|
• impairment in horizontal VOR but not in vertical VOR
• defects in VOR are more predominant at high frequencies
|
|
• 3 rather than 4 waves are present ipsilaterally and the third wave has a longer latency and is not followed by any identifiable wave
• the appearance of contralateral wave IVc is delayed compared to controls
