What is a media genius core?
Incoming sensory entry is directed to the cortex through the structure called thalamus. Many different groups of neurons include thalamus and one of them is the media genius core (MGN), also called the media genius body. MGN is connected to the auditory processing and the direction of attention to specific auditory stimuli. Conditional fear reactions including hearing impulses also use this structure in the brain. These regions have multiple input sources, but all receive information from Lower Colliculus, the initial area to which the auditory information is routed from the brain. In addition, everyone sends projections to the auditory cortex and other areas of the brain. The first subreare, ventral subnuleus, contains cells that are activated in response to certain sound frequencies. Information about sound intensites and how frequency and intensity differ between ears is also transmitted to the brain through these specific cells. Some cells in this area seem to respond to both sounds andto another sensory entry, such as a touch. They can also play a role in processing complex sounds because they respond to different frequencies. This area seems to be able to learn by learning.
The third main tuber of the media genius core is media subnuleus. Cells in this area process the duration of sound and volume. They also seem to respond to small frequency ranges instead of only one frequency. It seems that other sensory stimuli, such as visual information, affect how these cells react to sound.
Many cells in the media geniculate core send projections to the amygdala, the brain region contributes to learning and expressing reactions of fear. Activation of cells in MGN, which produces a chemical neurotransmitter glutamate, allows you to express the learned response to auditory fear. It seems that the same cells also contribute to the extinction of the reaction of fear.
cells in MGN that respond to the auditory stRES, so it does a specific pattern. These cells are connected to the creation of a certain ribonucleic acid (RNA) called c- fos . This process seems to result in the production of stress hormones called corticosteroids, hypothalamus. It seems that this initial induction of RNA and stress response depends at least partially, at least partially depends, at least partially.
