Creating a false memory

Memory is vital to form your personal identity. Memory gives us a sense of stability, a relationship with the reality we need to function daily. It is memory that gives us shape and tells us and those around us who we are. Despite the fundamental importance of memory, its basis for the human brain remains largely a mystery. Attempts have been made to develop computer models of the human brain. But it turned out that this part of the brain is much more complex and goes beyond any system invented until now. Because memory can disappear or can be forged. Recently, scientists have tried to probe memory at the cellular level, using optogenetics to manipulate neural circuits in animals. Despite the rapid progress, we are far from understanding the uproar of what memory means. It is easy to think that memory is normal, natural. But when a disease occurs, Alzheimer's, for example, then we only understand the mystery.

Can you trust your own memory?

People constantly remember past experiences. In a moment of silence, remorse, flashback or simply in the subway to the office. Any smell, color or sensation gives us a sense of ya-vu. Memory always works. He is always there to tell us who we are and why we are like that. Memory is the sum of our past experiences, mistakes, victories, defeats, love stories, friendships. In addition to external stimuli, there are internal stimuli that can trigger memories or lead to the formation of new ones.

However, cell populations have been discovered in a region of the hippocampus that can generate false memories. Scientists are trying to study their neural interactions and their behavior towards true memories. Optogenetics can help us understand this behavior and the formation of associative memory.

Memories can be unworthy of trust. So scientists have tried to create a false memory by manipulating these cells. The neurons reactivated later, conditioning the fear in a certain context. Then it is possible to generate a false memory through fear using artificial means.
Is there a false memory syndrome?

The medical response is definitely. Fake Memory Syndrome (FMS) describes a condition in which a person's identity and relationships are affected by memories that are incorrect but firmly believed. The origin of the term comes from Peter J. Freyd, who made that base popular. The term is not recognized as a psychiatric disease in medical textbooks. But the principle of memory that can be altered by external influences is overwhelmingly accepted by scholars.

False memories may be the result of memory recovery therapy, a form defined in the 1990s. Some of the prominent figures in the field are forensic psychologist Ralph Underwager, psychologist Elizabeth Loftus and sociologist Richard Ofshe.

Neuroscience tries to explain how brain activity determines knowledge. This means that we must first identify the regions of the brain responsible for the internal production of mental representations and the interruption of these activities to see how cognitive processes are affected. Specifically, people have a rich repertoire of mental representations generated internally by processes such as conscious or unconscious memory, dream or imagination. However, the way in which these internal representations can be combined with external stimuli to generate new memories has not yet been fully studied.

The scientists used laboratory mice for tests. Using fear as a conditioning method, episodes of memories that affected the hippocampus were triggered.
Hippocampus - the place where language, associations and space navigation are born

The hippocampus is an important part of the human brain. It is part of the limbic system (this is the basis of emotions) and is found below the cerebral cortex. He is responsible for language, associations and spatial navigation. In addition, this is where short-term memory transforms into long-term memory.

In the case of Alzheimer's, this region is the first affected. The hippocampus can also be affected in the absence of oxygen, encephalitis and epilepsy.

Scientists have also shown that activated cells in the hippocampus can be reactivated in times of fear. Therefore, a false associative memory based on fear will be formed as a stimulus. Memory is a natural construction. The act of remembering can be susceptible to change. In humans, gossip and the illusion of memory often occur. These phenomena often occur as a result of incorporating incorrect information into memories. And these come from external sources. Congenital studies have shown intense activity in humans in the hippocampus during the recall of true information, but also in the case of false ones. But it was not possible to find the exact place where they dissociated. Based on studies and laboratory experiences, scientists speculate that false memories and false memory can also be formed in humans in a natural context by internal factors determined by an already formed memory and its association with an external stimulus.
The human brain can store everything Internet

New research shows us that a human brain could store all the Internet content in memory. Scientists have discovered that brain cells use 26 different types of information coding. The computer only uses "1 and 0". Therefore, the brain can retain enormous information. A real blow to the world of neuroscience. Maybe movies like Total Recall, Matrix, Inception, Extraction are not that far from the truth. And our descendants could become a kind of Johnny Mnemonic of the future.

And the human brain could do with the energy that a light bulb needs. A computer must be 10 times stronger and use 1 GW, a complete nuclear station.
