Do you know that the human brain is the most vigorous “computer” of the modern generation? Today, in the digital era, when many processes are automated, the human brain remains the strangest thing in the world. Millions of nerve cells and connections between these cells still comprise lots of secrets and hidden facts.
The fundamental goal of this essay is to determine what the hippocampus is and what role it performs in the human brain.
Hippocampus is a part of the brain that has a look of a seahorse. The inner folds of the middle section of the brain are its location. There is one hippocampus on every side of the brain. This organ is comprised of three primary layers.
It stands to mention that the society knew about it more than three centuries ago and since that moment this brain part became the most studied one. The hippocampus function is to involve an individual in learning. Still, it is a part of the limbic system. Each scientist knows that this particular system is responsible for such emotions as aggression, drinking, eating, sexual activity and even anxiety. On that score, this organ is also a part of all these emotions.
Hippocampus acquired its name from the Latin language. It means “sea horse” (due to its form). Its exact location is between the cerebral cortex and thalamus.
The basic premise of the hippocampus is to help people process two kinds of memories: spatial relationships and declarative memories. The first type is responsible for involving routes. This kind of memories is kept in the right hippocampus.
Declarative memory is responsible for learning facts, speeches, events, etc. The hippocampus is critical for this memory type. There were made many scientific pieces of research and investigations in this particular area. Furthermore, more than 50 years ago, there was an individual, who complained about epileptic seizures that happen too often (for several times per one day). The surgeon made a decision to delete the hippocampus. The surgery helped him forget about epileptic seizures, but it changed his way of life. After that, he started complaining about various memory problems. The patient remembered what happened to him in his childhood, but he couldn’t remember the events that happened yesterday. To create new memories became a real issue for the man. Very often he forgot about what he was talking about several minutes ago and with whom.
Thanks to this person, scientists made progress in learning all memory capabilities. The hippocampus takes part in the encoding of events, sequences of events and other episodes of life.
We see what happens to a person if this organ is removed. The patient will experience the same health problems when the hippocampus is affected by diseases. The primary reason of the widespread Alzheimer’s disease is the hippocampus injury. Due to this process, the person can’t create and remember new events. Depression and stress also influence the hippocampus. It changes its size.
In sober fact, three illnesses affect this organ. These are:
It is evident that hippocampus is significant for the human memory. The modern scientists still are carrying out researches in this field.
