The '''uncus''' is a structure located in the [[medial temporal lobe]] of the [[brain]]. It is part of the [[parahippocampal gyrus]] and plays a significant role in the [[olfactory system]] and [[memory]] processing. The term "uncus" is derived from the Latin word for "hook," reflecting its hook-like shape.

== Anatomy ==

The uncus is situated at the anterior end of the parahippocampal gyrus, adjacent to the [[hippocampus]] and the [[amygdala]]. It is divided into two parts: the anterior and posterior segments. The anterior segment is involved in the olfactory system, while the posterior segment is associated with the hippocampal formation.

== Function ==

The primary functions of the uncus include:

* '''Olfaction''': The uncus is closely linked to the [[olfactory cortex]], which is responsible for the sense of smell. It receives input from the [[olfactory bulb]] and processes olfactory information.
* '''Memory''': The uncus is part of the [[limbic system]], which is crucial for memory formation and emotional responses. It works in conjunction with the hippocampus to encode and retrieve memories.

== Clinical Significance ==

The uncus can be involved in various neurological conditions, including:

* '''Uncal herniation''': This occurs when increased intracranial pressure causes the uncus to herniate through the [[tentorial notch]], leading to compression of the [[brainstem]] and potentially life-threatening consequences.
* '''Seizures''': Lesions or abnormalities in the uncus can lead to [[temporal lobe epilepsy]], characterized by complex partial seizures.
