Uncus

The uncus is a structure in the brain, part of the temporal lobe and the limbic system. It is located near the front of the hippocampus, and is involved in the processing of different types of sensory input.

Anatomy[edit | edit source]

The uncus is located in the medial part of the temporal lobe. It is formed by the anterior part of the parahippocampal gyrus, and is located near the front of the hippocampus. The uncus is divided into two parts: the amygdala and the entorhinal cortex. The amygdala is involved in processing emotions, while the entorhinal cortex is involved in memory and navigation.

Function[edit | edit source]

The uncus is part of the limbic system, a group of structures in the brain that are involved in emotion, memory, and behavior. The uncus is involved in the processing of different types of sensory input, including smell and taste. It is also involved in the formation of memories, particularly those related to sensory experiences.

Clinical significance[edit | edit source]

Damage to the uncus can result in a variety of neurological and psychiatric conditions. For example, uncus syndrome is a condition characterized by seizures, olfactory hallucinations, and memory disturbances. This syndrome is often caused by a tumor or other lesion in the uncus.

In addition, the uncus can be affected by Alzheimer's disease, a neurodegenerative disorder characterized by memory loss and cognitive decline. In Alzheimer's disease, the uncus and other parts of the limbic system are often among the first areas of the brain to show signs of damage.
