The superior olive complex (SOC) is a group of auditory nuclei in the brainstem of amphibians, reptiles, and mammals. One of the main functions of the SOC is Encoding cues contributing to vocal lateralization based on converging binaural ascending inputs from the two ventral cochlear nuclei.

What is the function of the upper olive pit?

The superior olive complex (SOC) or superior olive nucleus is a collection of brainstem nuclei, Plays a role in multiple aspects of hearing It is an important part of the ascending and descending auditory pathways of the auditory system.

What happens when the upper olive complex is damaged?

Unilateral or bilateral lesions of the superior olive complex (SOC) were performed by local injection of kainic acid via a micropipette stereotaxically lowered into the rat auditory brainstem.The effect of the disease is destroy cell body High quality olives that do not damage channel fibers.

What is the role of the ventral cochlear nucleus?

The ventral cochlear nucleus (VCN) has two main types of cells that are specialized to encode intensity (stellate cells) and time (dense cells), so Provides information about the location of the soundwhile the dorsal cochlear nucleus (DCN) encodes pitch information and analyzes sound quality.

What happens to the cochlear nucleus?

ventral cochlear nuclear cell extract Information carried by auditory nerves in firing timing and activation patterns of auditory nerve fiber populations.

Where is the cochlear nucleus located?

The cochlear nucleus is a group of two small special sensory nuclei in the upper medulla Cochlear nerve component for the vestibulocochlear nerve. They are part of extensive cranial nerve nuclei within the brainstem.

How many upper olive complexes are there?

have three Major SOC nuclei in most mammals studied: lateral superior olivary (LSO), medial superior olivary (MSO), and medial trapezoid (MNTB).

What is the olive complex?

Inferior olive pit (or « complex »), i.e. part of the oligocerebellar system Mainly involved in cerebellar motor learning and function. The superior olivary nucleus is thought to be part of the pons and part of the auditory system that helps perceive sound.

What is the role of the lateral lemniscus?

Anatomical Terminology of Neuroanatomy

The lateral lemniscus is a bundle of axons in the brainstem, Transmits information about sound from the cochlear nucleus to various brainstem nuclei and ultimately to the contralateral hypothalamus.

What is an oval?

The medulla, also known as the medulla, The lowest part of the brain and the lowest part of the brain stem… The medulla oblongata plays a key role in transmitting signals between the spinal cord and higher parts of the brain and in controlling voluntary activities such as heartbeat and breathing.

What is the core of Ambiguus made of?

(« Nucleus ambiguus » is marked in the center right.) The Nucleus ambiguus (« ambiguous nucleus » in English) is A group of large motor neuronslocated deep within the medullary reticulum named by Jacob Clarke.

What does the cerebellar peduncle do?

cerebellar peduncle is nerve bundles that allow communication between the cerebellum and the rest of the central nervous system. Three pairs of cerebellar peduncles carry out this communication. The lower foot brings sensory information about the actual position of body parts such as limbs and joints.

How many reticular structures are there in the brain?

The human reticular structure is almost 100 Brains nuclei, and contain many projections to regions such as the forebrain, brainstem, and cerebellum.

What does an ambiguity kernel do?

The fuzzy nucleus is the location of the motor cell body, which innervates the ipsilateral muscles of the soft palate, pharynx, larynx, and upper esophagus, and is the Primarily responsible for swallowing and speaking.

What is a red nucleus?

red core is Large structure in the center of the outer cover This involves the coordination of sensorimotor information. Crossing fibers of the superior cerebellar peduncle (the main output system of the cerebellum) surround and partially terminate in the red nucleus.

What is a trapezoid?

The trapezoid is part of the auditory pathway Some axons from the cochlear nucleus cross here or cross to the other side before proceeding to the superior olive nucleus. This is thought to help with sound localization.

How does the medial superior olive structure help with the sound localization test?

How does the medial superior olive structure aid in sound localization?medial superior olive structure As a relay station in the brainstem, input from both ears helps detect interaural time differenceswhich in turn is critical for localizing sound.

What is the role of the superior and inferior colliculi of the brain?

it acts as Channels for almost all auditory signals in the human body. Its main functions are signal integration, frequency identification and pitch discrimination. It also processes sensory signals from the superior colliculus located above it.

Where does the cochlear nucleus transmit auditory information?

Information is transmitted from receptors in the organ of Corti (cochlear hair cells) of the inner ear to the central nervous system, by vestibulocochlear nerve (CN VIII). This pathway eventually reaches the primary auditory cortex for conscious perception.

Where is the medial geniculate nucleus located?

medial geniculate nucleus formation A small protrusion on the subthalamic caudal surface between the lateral geniculate body and the occiput (Figure 21.11; see also Figure 15.10).

Is the cochlea part of the nervous system?

The cochlear nerve (also the auditory or auditory neuron) is one of two part Part of the vestibulocochlear nerve, the cranial nerve that resides in the amniotic membrane, and the other part is the vestibular nerve. The cochlear nerve transmits auditory sensory information directly from the cochlea in the inner ear to the brain.

What are the three cerebellar peduncles?

There are three on each side: Inferior cerebellar peduncle (#4025, #6172), middle cerebellar peduncle (brachium pontis) (#8361, #6553) and superior cerebellar peduncle (brachium conjunctivum) (#6554). The middle and inferior cerebellar peduncles contain most of the cerebellar afferents.

What is the literal meaning of cerebellar peduncles?

Medical definition of cerebellar peduncle

: any of the three large bands of nerve fibers that connect each hemisphere of the cerebellum to the parts below and below the brain Front: a: The part connecting the cerebellum and midbrain.

What is the cerebellar peduncle made of?

The superior cerebellar peduncle is a pair of white matter structures that connect the cerebellum and midbrain.The middle cerebellar peduncle connects the cerebellum to the pons and is entirely centripetal fibers.
