The Old Cortex (lat. archicortex) is one of the two main layers of the cerebral cortex, which is located in the central part of the hemisphere and has a thickness of about 1 mm. It is the most ancient part of the cortex, which was formed during the process of evolution in mammals.
The cortex plays an important role in processing information related to sensory sensations (eg, vision, hearing, touch) and motor coordination. It is also involved in regulating various body functions such as breathing, heart rate and blood pressure.
The structure of the Old Cortex includes various types of neurons that are specialized in processing certain types of information. For example, neurons in the visual cortex are responsible for processing visual signals, and neurons in the motor cortex are responsible for controlling movements.
Although the Old Cortex is one of the main layers of the cortex, its role in brain function is not limited to processing sensory information. It also plays an important role in memory formation, learning new skills, and decision making.
Overall, the Old Cortex is a complex system of neurons that plays a key role in controlling body functions and processing information. Its study can help to better understand the mechanisms of brain function and develop new methods for treating various diseases associated with dysfunction of the cortex.
