behavior/neurological
• when the platform is removed from the water maze heterozygous mice spend more time in the former platform quadrant suggesting better retention of the platform position
|
nervous system
• at P1 and 12 weeks glycine uptake in brain homogenates is significantly reduced compared to wild-type
|
• low concentrations of amphetamine fail to disrupt pre-pulse inhibition in heterozygous mice
|
• perfusion with glycine or D-serine fails to increase the amplitude of NMDA receptor currents of CA1 pyramidal cells
