Memory and Brain Mechanisms
The goal of this paper is to understand how the brain and memory processes are intertwined and how certain techniques can improve these processes. In an essay of 1,000-1,250 words, discuss how memories are formed and maintained in the brain through the actions of neural circuitry. Use at least four scholarly resources to address the following questions:
How are memories formed in the brain (using neural circuitry), and how are they maintained?
Given what we know about brain mechanisms in memory, are our memories accurate? Explain your answer using information on how memories are stored in the brain. Include an explanation of how working memory is similar to and different from long term memory.
How can knowledge of the brain and memory systems be used to help individuals suffering from memory problems (e.g., poor memory, amnesia, PTSD)?
Sample Answer
How are memories formed in the brain (using neural circuitry), and how are they maintained?
Memories are formed in the brain through a process called neural plasticity. Nability eural plasticity is the of the brain to change and adapt in response to experience. When we learn something new, the connections between neurons in our brains are strengthened. These strengthened connections form the basis of our memories.
The process of memory formation can be divided into three stages: encoding, storage, and retrieval.
- Encoding is the process of taking in new information and converting it into a form that can be stored in the brain. This process involves the hippocampus, a small structure in the medial temporal lobe. The hippocampus is responsible for creating new memories and linking them to existing memories.
- Storage is the process of maintaining memories over time. Memories are stored in a distributed network of neurons throughout the brain. This network includes the hippocampus, as well as other areas of the brain such as the cortex and the amygdala.
- Retrieval is the process of accessing memories from storage. Retrieval is often triggered by a cue, such as a smell, a sound, or a visual image. When a cue is encountered, it activates the network of neurons that stores the memory. This activation allows the memory to be brought back into consciousness.
