Definition:
(n.) The process of laminating, or the state of being laminated.
Example Sentences:
(1) Although the reeler, an autosomal recessive mutant mouse with the abnormality of lamination in the central nervous system, died about 3 weeks of age when fed ordinary laboratory chow, this mouse could grow up normally and prolong its destined, short lifespan to 50 weeks and more when given assistance in taking paste food and water from the weaning period.
