The term "paleencephalon" refers to an area of the brain located in the cerebral cortex, and is part of the limbic system. Synonyms for "paleencephalon" include the olfactory cortex, limbic cortex, and archipallium. The olfactory cortex is responsible for processing and recognizing smells, while the limbic cortex plays a role in emotions and memory formation. The archipallium is thought to be an evolutionarily ancient area of the brain and is believed to be involved in instinctual behaviors. Understanding the synonyms for paleencephalon can be useful in neuroscience research and medical diagnoses.
