behavior/neurological
|
• in an open field and elevated plus maze
|
|
• in a Morris water maze, escape latency is increased compared to in wild-type mice
|
nervous system
|
• mice exhibit decreased paired-pulse facilitation compared with wild-type mice
• however, long-term and post-tetanic potentiations are normal

|
• mice exhibit decreased paired-pulse facilitation compared with wild-type mice
• however, long-term and post-tetanic potentiations are normal
|
behavior/neurological
|
• in a fear conditioning assay, mice exhibit reduced freezing, especially in the test of spatial context, indicating impaired learning and memory
• however, mice show normal social behavior in the three-chamber test
|
|
• in the elevated plus-maze test, mice spend more time in the open arm and less in the closed arm, indicating reduced anxiety
|
|
• mice cover a greater distance at a greater speed in the open-field test
|
nervous system
|
• the hippocampal dentate gyrus shows decreased thickness at 20 weeks of age, however the CA1 and CA3 regions are normal
|
|
• the number of CUX1+ neurons in layers 2-4 is reduced
• however, the corpus callosum appears normal
|
|
• mice show reduced thickness of cortical layers 2-4 at 5 and 20 weeks of age, whereas thickness of layers 5 and 6 remains normal
