What is an entorhinal bark?
Entorhinal bark is one of the most important memory centers of the brain. Its main function is to give messages to AZ hippocamp, which is considered one of the main parts of the brain and the epicenter of long -term memory and spatial navigation. Entorhinal cortex is located in the middle temporal lobe, under the cerebral peel and near the hippocamp. It is one of the first areas of the brain that has been affected by the accumulation of Alzheimer's disease. Entorhinal bark is usually considered part of this structure. Five senses transmits information about hippocamp through entorhinal cortex. Entorhinal bark also transmits messages between hippocamp and neocortex, an area of the brain that processes motor skills, conscious thinking and perception of the senses, between several other vital functions.
Entorhinal bark plays C C central role in memory. This area processes and combines memories, especially during sleep cycles. It also uses sensory information to derive whether it had previously experienced a specificSensory event. It is assumed that entorhinal bark retains the nervous plan of spatial movements. This area has a number of cells of cells that help individuals navigate clockwise or counterclockwise.
When Alzheimer's disease hits, it creates an amyloid plaque accumulation in the brain. Amyloid is a type of accumulation of fibrous protein that is a biological feature of Alzheimer's disease. After gathering in neocortex, it attacks entorhinal bark, making it one of the first affected areas of almosks affected by Zeimer's disease. Other proteins called neurofibrillary tangle also reach into entorhinal cortex before they reach other areas of the brain.
The acrual of these substances directly affects the ability of the entorhinal bark to function properly. In many cases, the whole atrophy of the entorhinal cortex during Alzheimer's disease. This process results in the main problemY short -term memory preservation, memory consolidation and spatial navigation.
Further research of entorhinal bark suggests that the region can also play a role in the development of depression and schizophrenia. One study showed that the right side of the entorhinal cortex was significantly lower in older patients with clinical depression. Also, brain atrophy associated with schizophrenia can begin in the entorhinal cortex.
