How does memory work?

Definitions of 5 vocabulary terms

Memory: The process of our brain maintaining the information over time.

Neurons: Cells that transmit nerve impulses in the brain

Neurotransmitters: Chemicals that send signals from one nerve cell to another.

Long-term potentiation (LTP): The ability of brain cells to increase the strength between brain cell connections.

Synapses: A small gap of the neuron that carries the signal to the next neron.

Paragraph Description

The functions of a memory isn’t just about experiencing a event in life, make it into a memory and store inside the brain. Neurons communicate with other neurons when they recieve stimulation from same neurotransmitters and the strength of the connections is what tells us about how a memory works. It is said by William Griffith, Ph.D., a cellular neuroscientist and chair of the Department of Neuroscience and Experimental Therapeutics at the Texas A&M Health Science Center College of Medicine, that LTP, long-term potentiation explains memory a lot since it changes the strength of brain cell connections. If your brain has made a ‘strengthened synaptic contact’ and nerve cells transmitted signal to one another, then a momeory is made. To remember memories is by maintaing the LTP. When your losing strength in your LTP synaptic connections, this could cause cognitive loss and impairment. The decrease in neurons communicating to each other makes the connections weak, which makes it harder to recall memories. Memories can be thought back when you look or smell something as it relates to an event in a past. Behaviours such as addiction can be associated with memory as well because the pathways for addiction are strengthened. But there is more to be researched on how the brain generates, consolidates and retrieves memories.
