N normal phenotype
• almost 50% thinner than in controls
• layer is disorganized with a reduction in synaptic complexes
• mitochondria are swollen with severe disruption of cristae
• exhibits extracelluelar edema
• layer is thinner than in control littermates
• amplitude of b-wave responses is reduced and delayed at all flash intensities in 2 month old mice
