What is cranial nerve detects tastes?
The cranial nerves carry taste information into the brain to a part of the brain stem called the nucleus of the solitary tract. From the nucleus of the solitary tract, taste information goes to the thalamus and then to the cerebral cortex. Like information for smell, taste information also goes to the limbic system (hypothalamus and amygdala).
What cranial nerve is stimulated by the drug?
Vagus nerve stimulation involves the use of a device to stimulate the vagus nerve with electrical impulses.
