I'm not against eating meat (I eat meat everyday) but when that goats head was removed was the body still twitching and moving or was that just me who saw that? I thought that was supposed to be a quick, painless death.
You are right in your observation!
Body indeed was twiching
Pain is not something physical but the preception that is processed by Brain centre ( Thalamus to be specific ) and the information passed on to even higher centre that make one concious of pain
But all the sensory preceptions( almost ) has to pass through spinal cord to reach Brain and also all the Motor activity messages also pass through spinal cord from CNS to reach Periphery..
So when Head is cut suddenly animal might feel pain for the fraction of second while cuting is still in the process but once head is seperate
Brain stop recieving signals and hence cant precieve pain
But the Spinal cord still keep on firing neurons in uncontrolled or autonomus fashion and produce movemnets in the head less body without higher control.
