Remember is an experience over time. The various components that Create Memory that make up what we refer to as “memory” (sounds, smells, emotions, and images) are produced by several but related mnemonic systems.
Learning of some kind must take place in order for there to be a memory. In other words, knowledge needs to be obtained. Information needs to be stored in memory until it is required. When all is said and done, we employ this information by pulling it from memory and activating it.
These three phases of memory—encoding, retention, and retrieval—are named for memory researchers and accurately sum up the creation of the memory process.
The process of integrating new information with prior knowledge is known as the encoding phase. Everybody encodes events in a distinct way. If the term “table” needs to be encoded, you can do so using a semantic code that explains the meaning of the word as well as the feelings it often evokes in you, or a visual code that describes the appearance (size, form) of the object. The depth of encoding determines the intensity of the memory trace; the more deeply a stimulus is processed, the more probable it is that a lasting trace will be produced.
What factors influence retention quality? According to a well-known idea from the 1970s called the “levels of processing theory,” information is better retained when it is encoded based on meaning (deep processing). Repetition, or technically reiteration, is the most often used method for information retention.
How Chemical does the formation of a Memory Occur?
The primary signaling units in the neurological system are neurons which create memory. The morphologically distinct and well-defined sections of a typical neuron consist of the cell body, dendrites, axons, and presynaptic terminals. The nucleus, which houses the genes needed for their transcription into proteins, is found in the cell body, which serves as the metabolic hub of the organism. Both the solitary long axon and the many short dendrites branch off from the cell body. Dendrites are the primary structure for receiving messages from neighboring neurons. They branch out towards the exterior, much like a tree.
The primary component for sending electrical signals, or “action potentials,” from one neuron to another is the axon. The axon splits into thin branches close to its terminal portion, forming communication structures with neighboring neurons. The term “synapse,” which comes from the Greek word “synapsis,” meaning “connection,” refers to these communication connections. The presynaptic terminal refers to the input of the synapse that is part of the neuron that sends the action potential, and the postsynaptic terminal is the output that is part of the neuron that receives the signal. The synaptic cleft divides the two neurons, preventing them from really coming into contact.
There are vesicles containing a chemical neurotransmitter at the presynaptic location. A mechanism known as vesicular exocytose releases the neurotransmitter into the synaptic cleft when an action potential that has traveled along the axon reaches the terminal. Next, the neurotransmitter attaches itself to certain receptors on the membrane of the postsynaptic terminal. This binding will cause postsynaptic alterations that either increase or decrease the activity of the postsynaptic neuron, depending on the neurotransmitter that is released.
Certain brain circuits become appropriately activated as a result of an experience. Activated neurons’ synapses undergo biochemical reactions as a result of this neuronal activity, which quickly increases synaptic strength. When there is enough calcium input into the postsynaptic neuron or neuronal activity, the cell nucleus receives biochemical reactions that activate transcription factors, including the protein CREB, which controls the production of certain genes. The cascade of gene expression changes the connectivity of the active circuit by causing long-term circuit rearrangements and an increase in synapses.
