  • Essay / Memorization and its process in the human brain

    Memorization is very unique because of all the parts and functions of the brain, how people all have different levels of memorization, and how Old memories can impact new ones. Memorization was an ancient technique in Greece around 2,500 years ago where medieval scholars could remember their entire books and Cicero (Roman philosopher) used to memorize his speech. Over time, we gain more information about how memory works and what can influence it. Say no to plagiarism. Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”? Get an original essay Much of memorization is about parts of the brain working together. Part of the brain is the CREB gene, which was studied in rats, where it was "required for the creation of long-term memories." “The CREB gene accomplishes this task by coding for a protein that regulates the expression of other genes necessary for memory.” “The ability of CREB to regulate the cellular shape that receives memory – memory allocation – has led to the ‘allocation to link’ hypothesis.” When two memories are linked, that is, they share the same neurons, this triggers the CREB gene to increase, where it memorizes the second memory. In another study, they focused on an MCH (melanin concentrating hormone) neuron during sleep in mice. “When researchers tracked the MCH signal in mice, they found that the cell suppressed hippocampal neurons.” “The hippocampus is essential for memory formation, it is involved in short memory (lasts a few seconds) and helps consolidate or recognize and stabilize memories in the cortex.” “The cortex is a long-term memory (of events that occurred between minutes and decades earlier) and reinforced here.” “The hippocampus also plays a role in the formation of autobiographical memories, while the hippocampus, parahippocampus, cortex, and medial entorhinal cortex help process spatial memories such as where events occur.” In the two mentioned neuron studies, neurons travel and send signals in specific ways. First, “neurons receive signals via dendrites, branches that extend from the cell body.” Then, "signals from the dendrites are organized within the cell body. If the signal is strong, neurons will fire, sending electrical activity along its axon." Then, “when an electrical signal reaches the end of the axon, it triggers the release of neurotransmitters in the synapses between two neurons and binds the receptors located at the end of the dendrites to the second neuron. Later, “if the first two neurons repeatedly activate the second neuron, the connection strengthens; when neurotransmitters bind to the second neuron, calcium flows into the second cell. Calcium activates enzymes that increase the number of receptors on the surface of cells, which means a greater response next time; As an added bonus, other proteins trigger the production of scaffolding proteins, which can stabilize the synapse, thereby solidifying two neuronal connections. » Everyone has a different level of memorization due to the way our brains work. In 1953, Henry Molaison had his temporal lobe, which includes the hippocampus on both sides of the brain, removed to treat his epilepsy. “Even though the operation reduced his seizures, he was unable to form new memories. He remembered the experiences and..”
