How are odor molecules converted into olfactory signals and transmitted to the brain? American scientists Richard Axel and Linda Barker found that when odor molecules are combined with olfactory receptors, odor molecules as chemical signals pass through C. TP, the complex role of olfactory receptors of binding proteins (commonly known as C. protein), is transformed into electrical signals and then starts a relay run along the olfactory nerve. These signals first enter the skull from the nasal cavity and are finally transmitted to Certain subtle areas of the brain's olfactory cortex, where they are translated into specific olfactory information, are perceived by people. This is the complete theory of olfactory signal pathways that Axel and Buck have described for us. What is the following misunderstanding of Axel and Buck's olfactory signal pathway theory? ['Odor molecules are transformed from chemical signals to electrical signals by the olfactory receptors belonging to the G protein.', 'The end of the olfactory signal pathway is some fine regions in the olfactory cortex of the brain.', 'The olfactory signal pathway theory describes the process by which odor molecules are converted into olfactory signals and transmitted to the brain.', 'Smell molecules that are chemical signals reach certain fine regions of the olfactory cortex of the brain and are translated into olfactory information.']
