How Memory Works: The Science of Recall and Powerful Ways to Improve It

How We Remember

We rely on memory every single day—whether it’s remembering where you left your keys or recalling a fun vacation from years ago. But understanding how memory works is a fascinating process involving different brain regions, neural connections, and cognitive functions. Memory isn’t just about storing and retrieving information—it’s about memory formation and retention, which allows us to navigate life, solve problems, and build relationships.

Understanding how to increase memory can allow you to maintain sharp cognitive function and protect long-term brain health. Whether you want to improve learning, recall details more easily, or prevent memory decline, knowing how memory is created and maintained is the key to boosting brain performance.

How Memory Works: The Science Behind Recall

Memory is the brain’s system for gathering, storing, and retrieving information. But it’s not as simple as hitting “save” on a computer. How memory works is through a dynamic process where different brain regions work together to ensure you can recall important details when needed.

At the core of memory formation and retention is the hippocampus, which consolidates short-term memories and moves them into long-term storage. Other parts of the brain also play key roles:

• Prefrontal Cortex – Responsible for short-term and working memory.
• Basal Ganglia – Manages long-term procedural memory (habits and skills).
• Amygdala – Strengthens emotional memories, helping us remember experiences tied to strong emotions.

Memory is more than a mental filing system—it is shaped by neurons, emotions, and experiences. Strengthening it is key to better focus, deeper connections, and lifelong brain health.

How Are Memories Created?

Memory formation involves the brain building and strengthening connections between neurons. This process is known as “synaptic plasticity,” and it reshapes the brain, turning new information into long-lasting memories.

Here are the four key steps in how memory is created:

• Gathering: You take in information from your surroundings.
• Encoding: Your brain translates that information into a format it can store.
• Storage: The brain organizes and stores it for future use.
• Retrieval: You access stored information when needed.

At the core of memory function is the hippocampus, which consolidates short-term memories and helps move them into long-term storage. Other areas of the brain—like the prefrontal cortex for short-term memory and the basal ganglia for long-term procedural memory—play vital roles as well.

Memory is more than a mental filing system; it’s the foundation of our identity, shaped by neurons, emotions, and experiences. Learning how to increase memory is key to sharper focus, deeper connections, and lifelong brain health.

What Are the Types of Memory?

Memory is not a single system; different types of memory serve different functions. Understanding the various types helps improve memory formation and retention and offers insight into how to increase memory effectively.

1. Working Memory

Working memory is like the brain’s temporary workspace. It helps you hold small amounts of information while completing tasks—like remembering a phone number long enough to dial it or following directions in a new area. It’s quick, flexible, and essential for problem-solving and learning.

Working memory differs from short-term memory because working memory actively manipulates information. Think of it as juggling tasks in your mind, like solving a math problem, while short-term memory simply holds the information for a brief period.

2. Short-Term Memory

Short-term memory temporarily holds information for a few seconds or minutes before it’s either forgotten or transferred to long-term storage. You can boost short-term memory through chunking (grouping information) or rehearsing it repeatedly.

While short-term memory doesn’t manipulate information like working memory does, it acts as a temporary holding space before deciding whether information is important enough for long-term memory.

3. Long-Term Memory

Long-term memory is the brain’s archive, where information is stored for years—or a lifetime. The easiest way to think of long-term memory is as a vast storage system. It’s divided into two categories:

• Declarative (explicit) memory: This stores facts and events, like the capital of a country or the details of your last birthday.
• Non-declarative (implicit) memory: This covers skills and habits you don’t consciously think about, like riding a bike or tying your shoes.

4. Subconscious Memory

Subconscious memory operates below your awareness, storing automatic behaviors and beliefs that guide your actions without conscious effort. For example, driving a familiar route or brushing your teeth is influenced by subconscious memory.

Examples of Subconscious Memory:

• Automatically reaching for your phone when you hear a notification sound.
• Typing without looking at the keyboard after years of practice.
• Reacting to a specific smell that triggers a childhood memory.

How to access subconscious memory:

• State-Dependent Memory: Revisit the place or mental state where the memory was formed.
• Sensory Triggers: Certain sights, sounds, or smells can bring subconscious memories to the surface.
• Hypnosis and Guided Meditation: Techniques like these can help you access deep layers of your subconscious.

5. Conscious Memory

Conscious memory, also called explicit memory, involves actively recalling information, such as the plot of a favorite movie or facts from a book. This type of memory can be improved through techniques like repetition and mnemonics.

The Role of Emotion in Memory Retention

Emotionally charged events—whether positive or negative—are often remembered more vividly and for longer periods than neutral experiences. Why? Because emotion acts as a memory booster, making those moments stand out. Memories tied to strong emotions, like fear or joy, trigger the release of stress hormones such as noradrenaline and glucocorticoids. These hormones can enhance memory retention up to a point. However, chronic stress can impair memory function, making it harder to recall details clearly.

Why Do We Forget Some Memories?

Forgetting is a normal brain function that helps prioritize useful information while letting go of unnecessary details. However, stress, trauma, and lack of sleep can negatively impact how memory works. Extreme cases, such as memory suppression, occur when the brain blocks painful memories to protect emotional well-being.

How to Increase Memory and Protect Brain Health

Now that you understand how memory works, let’s talk about some tips on how to increase memory and protect brain health. Here are the easiest ways to boost your brain function:
Nootropics and Supplements: Supplements like creatine, lion’s Mane, NAD+, and Omega-3 fatty acids support cognitive function and memory. Nootropics enhance brain health by improving blood flow, boosting neurotransmitter production, and protecting brain cells.

• Adaptogens: Herbs like ashwagandha, ginseng, and bacopa monnieri have been used for centuries to help with stress, focus, and memory. These adaptogens reduce inflammation and oxidative stress, which are key factors in cognitive decline.
• Key Nutrients: Vitamins such as B12, folate, and vitamin D play crucial roles in maintaining brain health. B12 and folate support neurotransmitter production, while vitamin D helps protect brain cells and overall cognitive function.
• Sleep: Sleep is essential for memory consolidation, the process that converts short-term memories into long-term ones. Aim for 7-9 hours of quality sleep each night to allow your brain to repair, regenerate, and store the day’s memories.
• Exercise: Regular physical activity promotes healthy blood flow to the brain, increases brain-derived neurotrophic factor (BDNF), and reduces stress. Exercise also enhances synaptic plasticity, which supports memory formation.
• Brain-Training Exercises: Engage in puzzles, memory games, learning new skills, or reading to challenge your brain and improve memory.
