Non-Intentional N-Acetylcysteine Overdose Associated with Cerebral Edema and Brain Death.

N-acetylcysteine is the established treatment for acetaminophen toxicity. This medication's complex dosing schedule engenders a high incidence of medication errors. While nuisance side effects are common, only rare case reports describe serious outcomes associated with N-acetylcysteine administration, all of which take place in the setting of non-intentional N-acetylcysteine overdose.

Visual task complexity and eye movement patterns influence measures of human neurovascular coupling.

Human neurovascular coupling research conventionally aims to selectively activate the posterior circulation using a visual task. Different research groups use divergent visual tasks ranging in complexity and eye movement patterns with potential confounding effects. To understand the role of task complexity and eye movement patterns in neurovascular coupling, we performed a series of experiments with visual tasks ranging in complexity, eye speed, and eye movement amplitude.
