CNI – The Vital Role of the Olfactory Nerve in Human Sense of Smell and Memory Processing

what is the function of CNI (olfactory)?

smell (special sensory)

CNI, also known as the olfactory nerve, is responsible for the sense of smell in humans. The function of the olfactory nerve is to detect and transmit the information related to the perception of smell from the olfactory epithelium, which is located in the upper part of the nasal cavity, to the olfactory bulb in the brain. The olfactory receptor neurons located in the olfactory epithelium detect the odor molecules, and the signals are then transmitted through the axons of the olfactory nerve to the olfactory bulb. The olfactory bulb is responsible for processing the olfactory information and sending it to other parts of the brain for further processing, including the amygdala and hippocampus, which are involved in emotion and memory, respectively. Overall, the function of the CNI is essential for detecting and recognizing different scents, which can have various emotional and physiological effects on the body.
