behavior/neurological
• mutants attend less accurately to short, spatially unpredictable stimuli when the attentional demand of the task is high and also show a general tendency to make more perseverative responses than wild-type mice
• mutants initially respond as accurately as wild-type mice, however subsequently they fail to sustain their attention over the duration of the task, indicating reduced vigilance, or ability to sustain attention over a long period of time
• treatment of mice with the cholinesterase inhibitor donepezil results in an enhanced ability to sustain attention
