behavior/neurological
• following treatment with pilocarpine, mice exhibit a shorter latency to the first epileptiform discharge and first seizure episode compared to wild-type mice
• however, duration of seizure episodes was not different than in similarly treated wild-type mice
• in a wire-hang and rotarod test
• grip strength is impaired
• however, grip strength can be improved by prior injections of cholinesterase inhibitors
• mice exhibit a deficit in social recognition memory compared to wild-type mice
• mice are unable to maintain long periods of physical activities unlike wild-type mice

nervous system
• following treatment with pilocarpine, mice exhibit a shorter latency to the first epileptiform discharge and first seizure episode compared to wild-type mice
• however, duration of seizure episodes was not different than in similarly treated wild-type mice
• steady-state depression of evoked endplate potential is greater than in wild-type mice
• mice exhibit smaller and less frequent miniature endplate potentials than in wild-type mice
• acetylcholine release is decreased compared to in wild-type mice
• acetylcholine levels in the brain are increased compared to in wild-type and heterozygous mice due to reduced release

homeostasis/metabolism
• mice are unable to maintain long periods of physical activities unlike wild-type mice
