5 new vocabulary:
–synaptic connections: a conjunction between nerve cells within the brain that pass a signal from neurones to neurones.
–neurotransmitter: a chemical substance which is released at the end of a nerve fibre by the arrival of a nerve impulse and allows the transmission of signals.
–neurones: a specialized cell transmitting nerve impulses; a nerve cell.
–LTP: is a persistent strengthening of synapses based on recent patterns of activity.
–cognition: the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses.
How does memory work?
Scientist have done many experiments and a lot of research on the brain and especially how the brain remembers something. However, the memory of our brain is still a big mystery. Due to this, scientist only have a guess on how the brain gathers memories. They think that the more an event is repeated or the bigger the effect of the event, the more you will remember it. Neurones are nerve cells within your brain and these neurones pass information to each other through synaptic connection. Although that is true, this happens when certain neurotransmitters are present. However, the memory only really “sticks” in your brain when the same neurotransmitters are repeated multiple times. This repetition between the neurones makes them stronger and this is act of repetition is called long-term potentiation (LTP). LTP happens through cognition. If you can remember many memories from long ago it means you have a strong LTP. When this LTP is kept and excised the memory is formed and stored in our brain within the long-term memory section. On the other hand, cognitive loss can happen if a strong LTP memory is lost. These could be lost my a brain damaging accident.
