N normal phenotype
behavior/neurological
• mice exhibit impaired contextual fear memory, spending less time freezing in a context in which they received 2 tone-shock pairs
• however, mice show normal cued fear memory
• in the Morris water maze, mice show mildly impaired spatial learning and memory, showing fewer platform crossings during the training phase and on day 4 of the probe trial, but not on day 7
• mice exhibit anxiety-like behavior in the elevated plus maze, making fewer open arm entries and having a lower ratio of open arm entries to total arm entries
• in the novel object recognition task, mice do not exhibit a preference for the novel object over a familiar object as is seen in wild-type mice
• mice are hyperactive in the open field
• mice display stereotypic behavior in the marble burying task, burying more marbles and at a faster rate
• mice show deficits in social interaction, with mice showing no preference for the stranger mouse versus an inanimate object as seen in wild-type mice

nervous system
• mice exhibit higher levels of protein synthesis in the brain than wild-type mice

phenotype observed in males
N normal phenotype
behavior/neurological
• although learning ability in the acquisition and memory phases of the water-based Y maze and modified Morris water maze tasks are intact, males are impaired in locating the new platform positions in the reversal phases
• mutants exhibit increased self grooming
• males exhibit mild hyperactivity, however no impairments in motor coordination, motor learning and sensorimotor gating
• males exhibit repetitive digging behavior in the marble-burying test
• males do not show a preference for a nonspecific stranger versus a new, inanimate object
• males exhibit diminished reciprocal interactions with a freely moving stranger mouse
• treatment with 4DGI-1, an inhibitor of Eif4e-Eif4g interactions, results in a decrease in repetitive behaviors, perseverative behaviors, and in social behavior deficits

nervous system
• about 12% increase in spine density and smaller spine volume in layer 2/3 medial prefrontal cortex pyramidal neurons
• mutants exhibit an increase in the frequency, but not amplitude, of miniature excitatory postsynaptic currents in layers 2/3 of acute medial prefrontal cortex slices
• mutants exhibit an increase in the amplitude, but not frequency, of miniature inhibitory postsynaptic currents in layers 2/3 of acute medial prefrontal cortex slices
• mutants exhibit enhanced long-term depression in the striatum
• mutants exhibit enhanced hippocampal metabotropic glutamate receptor dependent (mGluR)-long-term depression
• treatment with 4DGI-1, an inhibitor of Eif4e-Eif4g interactions, normalizes the enhanced striatal long term depression
