How Does Memory Work? |I&S

In class we have been talking about memory. And this is an summary of “How does memory work?” by ScienceDaily.

New Vocabulary
ethernet: a way of connecting several computers to create a local area

neurotransmitters: a chemical that is released by a nerve, which allow signals to travel

long-term potentiation: repeated increase of the strengths between synapses

cognitive: process of gaining knowledge and understanding it mentally, like thinking and learning

impairment: being weakened or damaged

Summary
Memory is created when neurons communicate with each other. They do this through synaptic connections when certain neurotransmitters are there. However they only communicate when they get a same stimulus repetitively by the same neurotransmitters. And depending on the strengths of these connections it changes how a memory is formed, similar to a ethernet cable, which the durability is changed by how it is recognized by your brain (ScienceDaily). A memory is formed if the long-term potentiation (LTP) is maintained. This happens when the nerve cells talk to each other without further stimulation by the neurotransmitters. The strength of the LTP also effects your ability to recall memories, so when you lose your LTP, it causes cognitive loss and impairment. This happens when you don’t have connection between the nerve cells and they don’t talk to each other that often. Kind of like working out, you can train your muscles to become stronger by training often but when you stop, you gradually lose that strength.
