What is the hippocampus in the human brain? What is the function of the hippocampus in the brain

It is a brain area that helps humans process long-term learning and memory of sound, light, taste, and other events, and plays the so-called "narrative memory" function. In medicine, the "hippocampus" is the cerebral cortex.

An internal fold that forms an arcuate bulge around the choroidal fissure at the base of the "lateral ventricles", which consists of two fan-shaped parts, sometimes referred to collectively as hippocampal structures. The function of the hippocampus is to charge the main memories of human beings in the near future, a bit like the memory of a computer, which clearly retains memories within a few weeks or months for quick access. Memory is actually nerve cells.

The form of connection between them. However, the storage or discarding of certain information is not based on conscious judgment, but by the hippocampus of the human brain. The hippocampus functions as a conversion station in the process of memory.

When neurons in the cerebral cortex receive various sensory or perceptual messages, they transmit them to the hippocampus. If the hippocampus responds, neurons begin to form persistent networks, but if this approved pattern is not passed, the experience received by the brain automatically disappears. Short-term memories in everyday life are stored in the hippocampus, and if a memory fragment, such as a ** number or a person is mentioned repeatedly in a short period of time, the hippocampus will transfer it to the cerebral cortex.

Become a permanent memory. Therefore, people with more developed hippocampus areas will have a relatively stronger memory. If the information stored in the hippocampus is not used for a period of time, it will be "deleted", that is, forgotten.

The information stored in the cerebral cortex is not permanently forgotten, and if you do not use the information for a long time, the cerebral cortex may "delete" the information. Some people experience the loss of some or all of their memories after an injury to the hippocampus. It all depends on the severity of the injury, i.e. whether the hippocampus is partially or completely out of action.

The most powerful doctor: The hippocampus tissue in the human brain, which is mainly responsible for short-term memory, should not be faulted.

Answer: The hippocampus of the brain helps humans process long-term learning and memory of sound, light, taste, and other events. This is also known as "narrative memory".Medically, the hippocampus is an inner fold of the cerebral cortex that forms an arcuate-shaped bulge at the base of the lateral ventricle around the choroidal fissure, which is composed of two fan-shaped parts, sometimes referred to collectively as hippocampal structures; The hippocampus functions as the primary memory of the human being in charge of the recent past, a bit like the memory of a computer, which vividly retains memories within a few weeks or months for quick access.

Memories are the form of connections between nerve cells. However, the storage or discarding of certain information is not a conscious judgment, but is handled by a small structure in the human brain, the hippocampus. The hippocampus functions as a conversion station in the process of memory.

When neurons in the cerebral cortex receive various sensory or perceptual messages, they relay them to the hippocampus. If the hippocampus responds, neurons begin to form persistent networks, but if this approved pattern is not passed, the experience received by the brain automatically disappears.

The hippocampus is mainly responsible for storing information, which is the key part of human learning and memory, but it is a temporary storage system, when a kind of information is contacted, it is stored in the hippocampus, and then the brain will regularly check the information to see if it has been used again, if the information is used many times in a certain period of time, then it will be judged that the information is useful, and then it will be transferred to another place in the brain, and it will be permanently preserved in a solidified form.

If the hippocampus is removed, it will not be able to convert short-term procedural memory into long-term memory. At the same time, the memory of the past will slowly fade.

The cerebral hippocampus is the name given to a part located within the temporal lobe of the brain, and there are two hippocampuses in humans, one in the left and one in the left and right cerebral hemispheres. It is part of the limbic system and plays a role in memory and spatial localization. The name** is derived from the curved shape of this part that resembles a seahorse.

In Alzheimer's disease, the hippocampus is the first area to be damaged: it manifests as memory loss and loss of orientation perception. Hypoxia of the brain (hypoxia) and encephalitis can also cause damage to the hippocampus.

In animal anatomy, the hippocampus is the oldest part of the evolution of the brain. **The hippocampus of the old cortex is especially pronounced in primates and cetaceans in marine life. However, the hippocampus of primates, especially humans, accounts for only a small percentage of the telencephalon compared to the relatively young cerebral cortex of the evolutionary tree.

Compared with the development of the neocortex, the growth of the hippocampus plays an important role in primates by causing a significant increase in brain volume.

The exact role can be found on Wikipedia.

part of the brain.

In the first 50s of the last century, scientists discovered that the "hippocampus" in the brain plays a crucial role in storing information—and if the hippocampus is removed, the previous memories will disappear along with it. But how do nerve cells in the hippocampus hold the information in place? Scientists have discovered that some molecules are involved in the formation of memories.

In addition, synaptic formation of nerve cells is also associated with memory. But scientists don't know enough about how memory works – and it's so important for understanding ourselves.

The hippocampus is mainly responsible for learning and memory, short-term memories in daily life are stored in the hippocampus, if a memory fragment, such as a ** number or a person is repeatedly mentioned in a short period of time, the hippocampus will transfer it to the cerebral cortex and become a permanent memory. Therefore, people with a more developed hippocampus will have a relatively stronger memory. If the information stored in the hippocampus is not used for a period of time, it will be "deleted", that is, forgotten.

The information stored in the cerebral cortex is not permanently forgotten, and when you do not use the information for a long time, the cerebral cortex may "delete" the information. Some people experience a loss of some or all of their memories after an injury to their hippocampus. It all depends on the severity of the injury, i.e. whether the hippocampus is partially or completely ineffective.

Studies have shown that damage to the hippocampus of the brain affects imagination.

Recent research by British scientists has found that people with damage to the hippocampus of the brain have poor imagination in addition to poor memory. According to foreign reports, scientists have previously known that damage to the hippocampus can lead to forgetfulness, and researchers at University College London in the United Kingdom have further explored the effects on other aspects.

Affected people in the hippocampus were asked to imagine a future meeting with friends or a Christmas party, or to be on a beach or in a bar, but they reported that they were unable to form a concrete image in their brains, replaced by a bunch of detached fragments of images. Researchers suggest that this may be because the hippocampus is responsible for providing the brain with an environment in which to construct various types of images. The researchers have published the findings in the Proceedings of the National Academy of Sciences.
