The Olfactory Process and its Effect on Human Behavior

The olfactory process and its impact on human behavior Childhood memory can be caused by many incentives, the most powerful of which is a specific scent. A few years ago, I had torn Christmas decorative boxes from the attic. One of the boxes contained an old, partly melted candle, which was placed in the basement of the fireplace and illuminated by Christmas Eve. From the yellow newspaper, spread each unique aromatherapy candle, I suddenly have vivid memories of my childhood experience.

The olfactory bulb is a special structure that processes the olfactory signal and sends its output to the olfactory part of the cerebral cortex. It is a major brain component of many vertebrates, but it is greatly diminished in humans and other primates (sensation is mainly obtained through visual sense rather than odor). However, the size is not the only difference. The shape is also very different. The hindbrain and midbrain of mammals are usually similar to other vertebrates, but the forebrain is largely different, the forebrain greatly expands and the structure changes. The cerebral cortex is the most prominent part of the brain in the brain. In vertebrates other than mammals, the surface of the brain is lined up in a relatively simple three-layer structure called the cerebral cortex. In mammals, the cerebral cortex evolves into a complex six-layer structure called the neocortex or the same cortex.

In most vertebrates, the olfactory bulb is the most elongated (anterior) part of the brain, as seen in rats. However, in humans, the olfactory bulb is located on the lower side (lower side) of the brain. The olfactory bulb is isolated from the olfactory epithelium of the mammal and is supported and protected by the ethmoid plate perforated by the olfactory axons. The bulb is divided into two different structures: the main olfactory bulb and the auxiliary olfactory bulb

The olfactory bulb is considered to be the most important site for processing olfactory information and processes the information after transducing epithelial cells of the nasal organ via the receptor. It was found that each recipient cell expressed only one form of receptor protein, thereby forming approximately 1000 different recipient cells. In addition, it has been found that similar receptor cell axons typically accumulate on glomerular-like glomeruli. These axons are located at the distal primary dendrite site and belong to the mitral valve cell synapse. As a result, a map of the olfactory space is generated on the olfactory bulb. Since the excitatory input of synapses widely disperses carbon dioxide cells within the bulb, it is known that each individual receptor cell in the bulb responds to a different kind of odor or smell. This indicates that the main function of the olfactory bulb is to decode the various contours of the synaptic input associated with various odors.
