Hillock (Colliculus, Pl. colliculi)

Mound (Colliculus, Pl. Colliculi): functions and location

The colliculus is a small elevation located in the midbrain. In particular, two pairs of colliculi, superior (superior) and inferior (interior colliculi), are located on the quadrigeminal plate. The colliculi are important neuronal centers and play a key role in processing information related to vision and hearing.

The superior colliculi are the supracortical centers of the visual analyzer and are responsible for processing visual information. They play an important role in spatial orientation and response to external stimuli. The superior colliculus is also involved in controlling eye and head movements.

The inferior colliculi (inferior colliculi) are auditory neuronal centers and are responsible for processing sound information. They play an important role in the recognition and localization of sound stimuli. The inferior colliculus is also involved in the control of reflexes associated with auditory stimuli.

The location of the colliculi in the midbrain is due to their role in transmitting information between different areas of the brain. The colliculi are connected to areas such as the cerebral cortex, cerebellum, medulla oblongata, and spinal cord. Thanks to these connections, the colliculi play an important role in motor coordination and sensory processing.

The colliculus is an important component of neuronal circuits associated with vision and hearing. Impaired functioning of the mounds can lead to various visual and hearing impairments, as well as impaired motor coordination. Although research into the functions of the colliculi continues, it is now known that these neuronal centers play an important role in processing information related to vision and hearing.

Colliculi (colliculus) are small elevations located on the upper part of the quadrigeminal plate of the brain. They are centers for visual and auditory information processing and participate in the formation of motor reactions of the body.

The superior colliculi, called the superior colliculi, are responsible for processing visual information from the eyes. They receive information from the optic nerves and transmit it to the cerebral cortex, where it is analyzed and interpreted. The superior colliculus is also involved in visual reflexes, such as turning the head or eyes in response to a change in visual stimulus.

The inferior colliculi, known as the interior colliculi, are auditory processing centers. They receive signals from the auditory nerves, process them and transmit them to the cerebral cortex for further processing. The inferior colliculus is involved in auditory reflexes and allows the body to respond to auditory signals, such as the sound of an alarm or an approaching object.

Both pairs of colliculi are located on the upper part of the roof of the brain - the quadrigeminal plate. The roof is the top part of the brain and consists of several layers of neurons that provide various functions of the brain. The roof also contains other structures such as the thalamus, hypothalamus and pituitary gland, which are involved in regulating many physiological processes in the body.

Thus, the colliculi are important centers for processing visual and auditory information in the brain. Their work allows the body to respond correctly to external stimuli and ensure normal functioning.

Colliculi are small elevations located on the quadrigeminal plate in the midbrain. They are part of the auditory-visual system and play an important role in processing information from the senses.

The mounds have two pairs: upper (superior colliculus) and lower (inferior colliculus). The superior colliculus is the supracortical center of the visual analyzer and is responsible for processing visual information. The inferior colliculus, in turn, is the auditory center and processes sound signals.

Both colliculi are connected to other parts of the brain, such as the thalamus and hypothalamus, which ensure the transfer of information between them. This connection allows the colliculi to communicate with each other and provide more accurate information processing.

In addition, the hillocks are involved in the formation of motor reactions. They control movements of the eyes and other parts of the body, and are also involved in the regulation of emotions and mood.

Thus, the colliculi play an important role in the functioning of the auditory-visual system, ensuring accurate and efficient processing of information coming from the senses, and ensuring the proper functioning of the motor and emotional functions of the body.
