paraJS1-Ex4/para[+] is a suppressor of bang sensitive | recessive phenotype of eas2
paraJS1-Ex4 dominantly partially suppresses the bang sensitive phenotype of eas2 homozygotes. The minimum voltage of high frequency stimulation of the brain required to induce seizure (the seizure threshold) of eas2 homozygotes is significantly raised by paraJS1-Ex4/+, but not to wild-type levels as it is by paraJS1.
