behavior/neurological
|
N |
• homozygotes exhibit normal spatial learning (water-maze test)
• homozygotes show normal motor coordination (rota-rod test)
• consistent with grossly normal hippocampal functions, acquisition and performance levels are only slightly, but insignificantly, reduced in the two-way active-avoidance paradigm
• other behavioral paradigms indicate normal gross sensory functions, reflexes, home cage activity, and food consumption

nervous system
|
N |
• homozygotes exhibit a normal brain anatomy; however, an up-regulation of chondroitin sulfate proteoglycan-3 (neurocan) protein is detected in the mutant forebrain
|
|
|
• the hippocampal CA1 region shows normal synapse distribution, frequency, and morphology
• basal properties and short-term plasticity of excitatory and inhibitory synapses to the pyramidal cells in the hippocampal CA1 region appear normal
• perineuronal nets are present around hippocampal nonpyramidal neurons in both wild-type and homozygous null mice; in mutants, however, the nets appear fuzzier and are less pronounced and less concentrated close to the plasma membrane
|
|
|
• homozygotes show significant defects in the maintenance of hippocampal LTP in brain slices, although the initial fEPSP slope is normal
