Archipallium

Archipallium (archipallium; archi- + anat. pallium cloak of the cerebrum) is the oldest part of the cloak of the cerebral hemispheres of the vertebrate brain. The archipallium is formed from the medial wall of the forebrain cavity and consists of the hippocampus and olfactory cortex. This part of the cerebral cortex plays an important role in processing olfactory information and memory formation. The archipallium is present in all terrestrial vertebrates, including reptiles, birds and mammals. It is evolutionarily older than other parts of the cloak - paleopallium and neopallium.

Archipallium is a term used in anatomy to refer to the mantle of the brain. The cerebrum, also known as the hemispheres, is part of the central nervous system and is responsible for many functions, including thinking, speech, vision and hearing.

The archipallium consists of several layers of tissue that cover the cerebral hemispheres and form the outer layer. It is about 1 mm thick and has many functions, including protecting the hemispheres from damage, regulating temperature and pressure inside the skull, and participating in memory and learning processes.

One of the main functions of the archipallium is its ability to process sensory information coming from the senses. It is also involved in regulating movement and coordinating body movements.

In medical practice, the archipallium can be damaged by head injuries, strokes or other diseases of the central nervous system. In such cases, damage to the archipallium can lead to impaired sensory and motor functions, as well as problems with memory and learning.

Thus, the archipallium plays an important role in the functioning of the central nervous system, and its damage can lead to serious consequences for health and quality of life.
