Abstract:
Visual impairment and visual hallucinations are diagnostic signposts of dementia with Lewy bodies (DLB). Visual impairment is easily explicable as a functional impairment that results from damage to the visual cortices, whereas there is currently no compelling explanations for the mechanisms of visual hallucinations and other false perceptions. Here, I review evidence regarding the phenomenology and mechanisms of false perceptions in DLB, and propose that false perceptions maybe behavioral consequence of aberrant cortical state caused by cholinergic insufficiency.

Lewis Acids and Bases
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...
