Insofar as both nostrils are anatomically separated, modifications in responses can be interpreted as a central regulation process. Results showed that sensitization was clearly related to central mechanisms contrarily to desensitization which depended only of peripheral level. | | Language | eng | | Pub Type(s) | Journal Article
