Advances in Understanding of Experimental Concussion Mechanisms ¹

This paper is an in-depth study of the mechanism of concussion. Prior to 1967, concussion experiments were conducted exclusively on dogs, but after results of trials on dogs, cats, and stumptail monkeys, the authors concentrated on the latter.

Varying numbers of blows, from different angles, were delivered to 12 monkeys. Results, both organic and behavioral, are discussed.
