How does adaptation occur?
Adaptation happens as a result of a different mechanism for each sense. Touching causes a liquid movement in the cytoplasm of the receptor cells. This movement is sensed by the cell and conveyed to the brain in the form of electric signals. Despite the continuation of touching, the cytoplasm movement in receptor cells is stopped after a while and no signal is sent to the brain. So, no touching is felt. But when touching stops, as a result of a liquid movement in the cytoplasm of the receptor cells, a new signal prompts the brain that “touching is over.” In short, only the beginning and the end of touching is communicated to the brain. Despite the continuation of touching between the beginning and the end, the brain (rather the “soul”) is not bothered by this redundant information. Even though, many types of receptors serve in the process of adaptation to touching, only six of them have been thoroughly studied and named. The adaptation is not the same in all receptors; fast and advanced
