What is olfactory bark?
sensory networks in the body generally have the corresponding areas in the brain they give them. The olfactory bark is a responsible area, in many animals, for receiving and processing the fragrance or olfactory entry. This area, located near the limbic system, just below the cerebrium, is a place where most scent -related signals are processed. Its purpose and location contribute to some of the symptoms that are observed in the disease -affecting brain -affected states, the largest area of the brain.
In other senses, the signals are first processed in thalamus, but olfactory bark receives information directly from the receptors. The honest receptors in the nose send signals to nearby olfactory bulbs, just below the frontal lobes of the brain, and these gearboxes are then transmitted to the olfactory cortex or lobe. Information can then be processed and projections send this data to Thalam, where it can be integrated with the Oossese information as vision. Many projections from this bark go to another lobe called island barkwhere neurons integrate olfactory signals with those related to the feeling of taste. This area is responsible for a close relationship between two senses.
other neuronal connections connect olfactory bark with amygdala, part of the limbic system involved in the perception of emotions and memory. This particular network may result in a strong connection between fragrances and memories. In addition, emotional and behavioral reactions to the fragrance are associated with projections that allow this bark to interact with the amygdala and thalamus. When an unpleasant odor is detected, the brain scanning revealed that blood flow increases in these areas, showing that they actively process information.
occasionally, there may be health conditions that are closely linked to actions and a unique position of olfactory bark. Some chemical compounds as well as electrical signals are able to cause seizures due to the presence of a trigger zone called an Uncusfound in this area. The seizure activity that begins in this area can often begin with an individual hallucination of aversive fragrance. Tumors that exert pressure on the UNCU can also cause this area to push against a certain skull nerves; This can lead to a number of consequences for sensory input and movement, in a state called Untal Hernation.
