Sensation is detecting stimulus from the environment. The main senses are vision, hearing, smell, taste, touch, motion, and balance. Touch is the first sense that is developed in the fetus and the last sense to leave us when we die. Touch is broken down into the feel of heat, cold, pressure, and pain.
Phoebe Gets Chicken Pox
In this scene from Friends Phoebe gets chicken pox for the first time and she passes it on to her friend. All they can think about is scratching the itchy spots. Phoebe's touch sensations are definitely in hyper drive. Especially the pain sensory.
Phoebe is also experiencing selective attention. Which means that her focus of conscious awareness a particular stimulus. The only stimulus that Phoebe can focus on is the itching and pain.
The pain circuit is when sensory receptors respond to potentially damaging stimuli by sending an impulse to the spinal cord, which passes the message to the brain, which interprets the signal as pain.
