behavior/neurological
• the vestibulo-occular reflex is less impaired in cwh homozygotes than in homozygotes for the sprl allele
|
• although homozygotes are able to swim at the water's surface, they swim in circles
|
• all homozygotes circle, whereas only approximately half of sprl homozygotes circle and homozygotes for a null allele were not found to circle

• normal ABR thresholds and vestibular sensory evoked potentials, normal appearing cochlea and otoconia in both the saccule and utricle, and intact otoconial membranes despite the vestibular dysfunction

• the vestibulo-occular reflex is less impaired in cwh homozygotes than in homozygotes for the sprl allele
