monocular rearing

an experimental paradigm in which an animal is raised from birth with vision restricted to one eye by suturing the eyelids closed or by inserting an opaque contact lens in one eye. Monocular rearing during the critical period has profound structural and functional consequences for the developing visual system, including a shift in the ocular dominance of cortical neurons to favor the nonoccluded eye and a broadening of the ocular dominance columns corresponding to the open eye.

anticholinergic syndrome

anticholinergic syndrome

a disorder produced by anticholinergic drugs and due to their antagonistic effects at acetylcholine receptors, marked by symptoms involving both the peripheral and central nervous systems. The former include dry mucous membranes, dry mouth, and flushed skin and face, whereas the latter include ataxia (unsteady gait), drowsiness, slurred speech, confusion and disorientation, hallucinations, and deficits, particularly of short-term memory. Tricyclic antidepressants, aliphatic phenothiazines, antiparkinsonian agents, and scopolamine are examples of drugs that can cause anticholinergic syndrome. This syndrome is often observed in patients receiving combinations of such drugs.
