behavior/neurological
• freezing is decreased relative to wild-type controls when placed in the training context 24h after training
|
• while freezing increased across trials, freezing to tone was decreased relative to wild-type controls
• however, no differences are detected in motor activity, auditory reactivity or pain responsiveness
|
• on the first day of reversal training homozygotes took longer to learn the new platform location compared to wild-type controls
|
• while escape latency decreases across trials in a Morris water maze, performance is impaired relative to wild-type controls
• however, no difference is detected in swim speed or distance traveled
