What is the inferior colliculus?
In the central part of the human brain, there are four large adjacent structures that are primarily reserved for visual and hearing senses. The largest two lobes, called colliculus superior, are associated with both eyes. The lower two, called the lower colliculus, are responsible for processing signals derived from left and right ears. These two important human senses are possible precisely because this simple, divided brain anatomy. Its twisted, narrowed and liquid chamber is lined with cilia-strap cells that vibrate in response to specific frequencies and trigger a nerve cell for electrically pulse. All nerve cells coming from Kochlea a lot of acoustic nerve. Several other main nerves converge with acoustic nerves to form a nerve bundle called lateral liniscus, which is heading to the brain.
The lateral entrance point of Lemniscus is the middle brain, just above and in front of the medulla or the brain, and under, and behind the brain lobes of the front brain. In addition to the basic neuroanatomy of the left and the PRAThe middle of the human brain is divided into the upper and lower half. The resulting four, roughly round lobes are called the corpus quadrigemina. The larger upper halves are the superior colliculi and the bottom of the bottom is the lower colliculi.
Lower Colliculus is organized in three parts. There is a compact central core or ganglium cluster of multipolar neurons. It is enclosed by outer dorsal and lateral bark, which are a thick belt of bimodal nerve cells derived from lateral lemniscus.
side lemniscus enters the brain at the base of lower colliculus. Some of the individual nerves of the lateral lemniscus go through and further on the thalamus and the temporal lobe bark, where signals from multiple sensory and cognitive sources can integrate. Some nerves end up in the central core. Most nerves go beyond and end on the lower colliculus on the opposite side.
almost all human auditory signaling pathways are directed to the lower colliculus. It also receives neural signals from the superior colliceculus, the somato-residential nerve fibers from the brain stem and the input of higher function from the auditory cortex of the front brain. Although these connections are mostly bimodal, most of the output signals of both lower collice are designed by the brain media genius body, whose function is similar to the switchboard for other cognitive analyzes. The role of lower colliculus is the most basic, such as the pitch resolution, frequency recognition and frightened reflex.
Most of the signals sent by the right -of -the -iced cross -ground lower colliculus of the human brain and vice versa for the left ear. This binaural parallel processing of mechanical energy of compressed air waves, otherwise known as sound, is essential for human perception. Unlike radar triangulation, one Colliculus compares a given signal with its counterpart on the opposite side of Colliculus for variable differences such as time delayand Doppler's shift to locate the sound source in three -dimensional space. Human binocular vision, processed by Twin Superior Colliculi, is allowed by the same basic principle.
