Did you know that people can experience a phantom limb sensation? Even after an amputation, individuals often feel sensations like itching or movement in the missing limb. This is due to the brain's representation of the body, which doesn't immediately adjust to the physical change. Techniques like mirror therapy, where the reflection of the intact limb tricks the brain into seeing the missing limb, have shown success in alleviating these sensations. This fascinating phenomenon illustrates how our perception and reality can sometimes differ dramatically.
