In Biology class we used to pith frogs before we dissect 'em. Using a pin, we puncture a hole through their skull. Then we move the pin about to destroy the brain. I think this is supposed to make dissection less painful for the frogs. They won't feel the pain from a cutting blade if they're brain dead...i suppose.
You can still test the stretch reflex even if their brain is destroyed since reflexes only need 3 components that are still intact in a pithed frog --
1. sensory afferent fiber
2. control center (spinal cord)
3. motor efferent fiber

∙ 9y agoAs long as the animal has been pithed recently a stretch reflex can be elicited. Reflexes are loops from the sensor to the spinal cord and do not require brain processing.

What is reflex and complex behavior in animal systems?
reflex action is that immediate response to the external stimuli which is provided for the spinal cord itself and not the brain and further the complex action is taken by brain by further thinking upon the matter
What is the difference between a behavioral adaptation and a learned adaptation?
A reflex is a response to a stimulus that the animal was born with, but a learned behavior is a response to a stimulus that the animal learns or is taught.
