The inferior colliculus (IC) (Latin for lower hill) is the principal midbrain nucleus of the auditory pathway and receives input from several peripheral brainstem nuclei in the auditory pathway, as well as inputs from the auditory cortex. [1]

2023年5月26日 · Internal Anatomy of the Midbrain. Two transverse sections of the midbrain will be discussed: the level of the inferior colliculus, and the level of the superior colliculus. Level of the Inferior Colliculus. The anteriolateral surface of the midbrain houses the paired crus cerebri. Four fibre tracts run within the crus:

2023年8月14日 · The inferior colliculus (IC; plural: colliculi) is a paired structure in the midbrain, which serves as an important relay point for auditory information as it travels from the inner ear to the auditory cortex.

2024年4月1日 · The auditory midbrain, also known as the inferior colliculus (IC), serves as a crucial hub in the auditory pathway. Comprising diverse cell types, the IC plays a pivotal role in various auditory functions, including sound localization, auditory plasticity, sound detection, and sound-induced behaviors.

2024年9月30日 · The inferior colliculus, despite its rather unassuming name, is anything but inferior when it comes to its importance in the auditory system. Situated in the midbrain, just below its flashier cousin, the tectum , this small but mighty structure serves …

Connecting the auditory brain stem to sensory, motor, and limbic systems, the inferior colliculus is a critical midbrain station for auditory processing.

The inferior colliculus (IC) is a midbrain auditory structure that integrates information from several ascending auditory pathways, descending corticotectal projections, intercollicular pathways and extra-auditory sources, particularly from the somatosensory system. Three subdivisions may be distinguished in the IC, both morphologically and on ...

2023年11月3日 · The function of the superior colliculi is to facilitate the ocular reflexes that mainly have protective functions, for example, covering your eyes upon a sudden onset of brightness. The inferior colliculi are connected with the cochlear nuclei and are involved in the processing of auditory information. They project to the medial geniculate ...

2023年10月30日 · The inferior colliculus consists of a large nucleus of gray matter that lies beneath a corresponding surface elevation located at the posterior surface of the midbrain. There are two inferior colliculi, one on each side of the midline.

Brainstem (dorsal view) A:Thalamus B:Midbrain C:Pons D:Medulla oblongata 7 and 8 are the four colliculi.. The midbrain is the shortest segment of the brainstem, measuring less than 2cm in length. It is situated mostly in the posterior cranial fossa, with its superior part extending above the tentorial notch. [2]The principal regions of the midbrain are the tectum, the cerebral aqueduct ...
