Primary Outcome Measures:
  • qEEG assessed through the absolutes alpha-power of the two occipital leads [ Time Frame: In each treatment period (1, 2, 3, 4) the measure will be taken on Day 1 prior to dosing of AZD1446 or placebo and1h, 2h, 3h, 6h, and 24 hour after dosing of AZD1446 or placebo ]

Secondary Outcome Measures:
  • qEEGs/ERPs assessed by mismatch negativity and p300 [ Time Frame: In each treatment period (1, 2, 3, 4) the measure will be taken on Day 1 prior to dosing of AZD1446 or placebo and1h, 2h, 3h, 6h, and 24 hour after dosing of AZD1446 or placebo ]
