Memorization is very unique because of all the parts and functions of the brain, how people have different levels of memorization, and how old memories can affect new memories. Memorization was an ancient technique in Greece around 2,500 years ago, where medieval scholars could remember all their books and Cicero (Roman philosopher) used to memorize his speeches. As time goes by there is more information about how storage works and what can affect it. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an Original Essay An important part of memorization is the parts of the brain working together. One part within the brain is the CREB gene, which was observed in rats, where it was “required for creating long-term memories.” “The CREB gene does this by encoding a protein that regulates the expression of other genes necessary for memory.” “The ability of CREB to regulate which cell shape memory is allocated to – memory allocation – has led to the “allocate to attach” hypothesis.” When two memories are linked, meaning they share the same neurons, it triggers upregulation of the CREB gene, where it remembers the second memory. In another study, they focused on a MCH (melanin-concentrating hormone) neuron during sleep in mice. “When the researchers monitored MCH signaling in mice, they found that the cell suppressed neurons in the hippocampus.” “The hippocampus is critical for memory formation, is involved in short-term memory (lasting a few seconds) and helps consolidate or recognize and stabilize memories in the cortex.” “The cortex is a long-term memory (of events that happened anywhere from a few minutes to decades ago) and it gets stronger there.” “The hippocampus also plays a role in forming autobiographical memories, along with the hippocampus, parahippocampus, cortex, and medial entorhinal cortex help process spatial memories such as where events occur.” Both studies mention neurons, there are specific ways neurons travel and send signals. First, “neurons receive signals via dendrites, branches that extend from the cell body.” Next, “the signals from the dendrites are organized in the cell body, if the signal is strong, the neurons will fire, sending electrical activity along its axon.” So, “when an electrical signal reaches the end of the axon, it triggers releases of neurotransmitters in the synapses between two neurons that bind receptors at the tip of the dendrites to the second neuron. Subsequently, “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, meaning a greater response next time; Additionally, other proteins trigger the production of scaffold proteins, which can stabilize the synapse, solidifying two neuronal connections. “Every person has a different level of memorization due to the way our brain works. In 1953 Henry Molaison had the temporal lobe that included the hippocampus on both sides of the brain removed to treat his epilepsy. “Although the surgery reduced his seizures, he could not form new memories. He remembered the experiences and people he met before the operation, but not after.” There are others who have the opposite level of memorization, for example Soloman Shereshevsky. Solomon could remember everything he had given his mind to and that.”
