Frog Nerve Reflex : Even after a frog has been killed, certain nerve pathways can still respond to stimuli. When the frog’s legs are placed in hot water, the heat can stimulate the remaining nerve endings, causing the muscles to contract and give the appearance of movement. This does not mean the frog is alive, as it is simply a post-mortem reflex. The phenomenon is interesting from a physiological perspective but is not an indication of life or consciousness in the frog | Hedi Science News
