In Biology Classes
This method also refers to a procedure used in biology classes to immobilize a specimen, for instance a frog, by inserting a needle up through the base of the skull (from the back) and then wiggling the needle around, destroying the brain. It allows for dissecting the frog, as well as observing its living physiology, such as the beating heart and expansion and contraction of the lungs, without causing unnecessary pain to the animal. The specimen remains living because respiration continues through the skin without cerebral control.
