An insular cell (c. insularis), also known as an “insular epithelium,” is a type of epithelial cell that forms the surface of the brain. It is located on the inner surface of the temporal lobe and is part of the cerebral cortex responsible for processing auditory information.
The insular cell plays an important role in the processing of auditory information, as it is highly sensitive to sound vibrations and can detect even very faint sounds. It is also involved in processing emotional signals such as fear and joy and can influence a person's mood.
In addition, the insular cell is involved in memory formation and learning. It forms connections between neurons, which allows information to be stored in the brain and used in the future.
However, despite its important role, the insular cell remains poorly understood. Research suggests that its functions may be linked to the development of depression and other mental disorders, so studying this cell could help develop new treatments for these diseases.
