Read this post to learn about the different types of memory and the parts of the brain that are responsible for them.
Short-term memory is the holding amounts of information in an active, readily available state for a short period of time.
An example would be trying to hold the answer to a test question in your head before a test, if you stop repeating it for as short as a few seconds, you will forget what you were thinking.
Often compared to short-term memory, working memory is a limited-capacity cognitive system, important for reasoning and guidance of decision making and behavior.
1) Explicit Memory
Explicit Memory is when you consciously memorize something, such as phone numbers, or your personal social security number.
Declarative Memory is a type of explicit memory. It is a recall of factual information such as a date of an event, faces, concepts, or rules to a game.
Three main types of declarative memory:
- Semantic memory – the recall of general facts, a part of the declarative memory.
- Episodic memory – the recall of personal facts, a part of the declarative memory.
- Autobiographical memory – refers to knowledge about events and personal experiences from the individual’s life. While similar to episodic memory, autobiographical memory only pertains to the individual events.
2) Implicit Memory
Implicit memory is an unconscious store of memory that can affect thoughts and behaviors even though the event of the memory is not remembered.
An example would be visiting a location as a child, and when you come back as an adult decades later, you remember the specific location of something.
Implicit memory includes:
- Procedural memory – which helps you remember how to perform actions or skills. An example of this would be remembering how to drive or tying a shoelace even after not doing so for a long time.
- Emotional memory – memories that evoke a strong emotional response, can have both declarative and procedural processes.
Parts of the Brain (Cortex) that are Involved in Memory
- Frontal Lobe – The frontal lobe is a very important coordinator of information, and thus important in working memory. The frontal lobe is also important for remembering what we need to do in in the future, select relevant memories for a given occasion, and coordinating various types of information into a memory trace.
- Temporal Lobe – The temporal lobe is the most associated with memory. Home of the hippocampus, the temporal lobe is associated with autobiographical memory and recognition memory.
- Parietal Lobe – The parietal lobe helps us direct our attention to the task at hand, and assists with verbal short-term memory.
Other Parts of the Brain Involved in Memory
- Hippocampus (spatial and recognition memory) – The hippocampus is usually the first part of the brain that would be damaged in Alzheimer’s disease [R]. The hippocampus also plays a big role in the transfer of short-term to long-term memory [R].
- Amygdala (emotional memory) – Involved in the transfer of memories to long-term memories of emotionally arousing events.
- Cerebellum (procedural memory) – The cerebellum plays a role in memory involving movement coordination and how to do repetitive day to day tasks.
- Prefrontal Cortex (process and retain information)
- Striatum or neostriatum (procedural memory) is important in the retrieval of procedural memory.
While different parts of the brain are associated with memory, learning and memory involve long-term potentiation (persistent strengthening of synapses), and long-term depression (long-lasting decrease in synaptic strength). These processes are involved synaptic plasticity.

Health Tools I Wish I Had When I Was Sick
At SelfHacked, it’s our goal to offer our readers all the tools possible to get optimally healthy. When I was struggling with chronic health issues I felt stuck because I didn’t have any tools to help me get better. I had to spend literally thousands of hours trying to read through studies on pubmed to figure out how the body worked and how to fix it.
That’s why I decided to create tools that will help others cut down the guesswork:
- Lab Test Analyzer – a software tool that will analyze your labs and tell you what the optimal values are for each marker — as well as provide you with actionable tips and personalized health and lifestyle recommendations to help you get there.
- SelfDecode – a software tool that will help you analyze your genetic data from companies such as 23andme and ancestry. You will learn how your health is being impacted by your genes, and how to use this knowledge to your advantage.
- SelfHacked Secrets – an ebook where we examine and explain the biggest overlooked environmental factors that cause disease. This ebook is a great place to start your journey if you want to learn the essential steps to optimizing your health.
- SelfHacked Elimination Diet course – a video course that will help you figure out which diet works best for you
- Selfhacked Inflammation course – a video course on inflammation and how to bring it down
- Biohacking insomnia – an ebook on how to get great sleep
- Lectin Avoidance Cookbook – an e-cookbook for people with food sensitivities
- BrainGauge – a device that detects subtle brain changes and allows you to test what’s working for you
- SelfHacked VIP – an area where you can ask me (Joe) questions about health topics
