How much pressure can we take on skin until we say it is painful, varies on location and between people, higher threshold in pain in the index finger in comparison to the neck muscle. When is heat able to be detected in terms of humans. What range of mechanical pressure can pain be sense. Many people with amputated limbs report feeling pain from their missing limb. A gate at spinal column controls whether pain receptors in the skin and organs is transmitted onto the the brain. Gate can incorporate both information from periphery along with information from the brain down. Balance of activation from peripheral pain signal and inhibition from brain results in final pain experienced/perceived.
