Habituation and adaptation to odors in humans
WebHabituation is a form of non-associative learning in which an innate (non-reinforced) response to a stimulus decreases after repeated or prolonged presentations of that stimulus. Responses that habituate include those that involve the intact organism (e.g., full-body startle response) or those that involve only components of the organism (e.g., … WebHumans have about 350 olfactory receptor subtypes that work in various combinations to allow us to sense about 10,000 different odors. 18. Correct option is option a. pressure and pain receptors (Humans have pain and pressure receptors in the body and when they are stimulated ,they might produce sensation of itching , vibration and tickling ) 19.
