How the brain and therapy work together

The Brain's Job: Keeping You Alive Through Predictions

Our brains are essentially prediction machines with one primary job: keeping us alive. To do this, they rely on past experiences to predict future events. This is all based on what we've encoded in our memory.

When we encounter danger in the past but only manage to cope with it instead of solving it, those coping mechanisms get stored in our memory. Then, when we face something similar in the future, our brain automatically uses those past coping strategies. It's like if you taste a delicious cake and later encounter ingredients like eggs, flour, and butter. Your brain might label the new dish as cake, even if it isn’t.

This automatic process helps the brain save energy. It's unconscious and hard to recognize, let alone slow down to evaluate whether the past is truly repeating itself.

The Hose and the Snake

Imagine seeing a hose coiled up on the floor and for a moment thinking it's a snake. Your brain uses the shape of the hose to make a quick judgment to protect you. After a second, you realize it’s just a hose, and you can go about your gardening.

In relationships, these automatic assumptions are harder to recognize. We often mistake our gut feelings for objective truth. For example, if you grew up with parents who couldn’t handle big emotions like sadness, anger, or fear, you might have learned to suppress these feelings to cope. This coping strategy gets encoded in your brain.

Coping vs. Solving

As an adult, when you feel sad, scared, or angry in a romantic relationship, you might automatically suppress these emotions. You might feel anxious, irritable, or distracted but not recognize the underlying sadness, fear, or anger. This can lead you to stay in unhealthy relationships because your emotions, which are meant to guide you, are being ignored.

The Role of Therapy

Describing this unconscious process is challenging because it's designed to be unnoticed. This is where therapy comes in. Good psychotherapy helps you recognize the core issues behind your behaviors, like difficulty focusing, irritability, numbness, or getting overly upset. Therapy guides you in creating new, healthier responses that truly solve your problems rather than just coping with them.

By working through these issues in therapy, you can update your brain's prediction models with new data that reflects actual solutions, allowing you to live a more fulfilling life.

How Our Brain Learns and Adapts: The Magic of Memory Reconsolidation

When we’re born, our brains aren’t fully developed; they’re like houses with just the framing up. So, in the beginning, we heavily rely on our lower brain areas and start interacting with the world through our core emotions. These primal interactions happen through instinctive reactions to our sensory experiences. The feedback from these experiences gets stored and helps us learn. Over time, with repetition, these experiences turn into long-term, non-declarative memories, creating implicit prediction models (see our easy to read post on implicit prediction models).

Our brains learn through a method called prediction error. If a prediction is wrong, we update it; if it’s right, we stick with it. This process, which Freud called the Reality Principle, helps us use energy efficiently while adapting to survive. Memories and predictions guide our actions, from our posture to social strategies and facial expressions. These non-declarative memories are (like Tinactin) quick-acting and long-lasting, making them reliable for forming automated prediction models, even though updating them can be tough.

However, these memories can be updated through a process called memory reconsolidation. When we recall and viscerally feel these implicit memories, they become destabilized and open to new information before consolidating again. The provides a potential to change deeply held connections between emotions, events, and self-protective behaviors if new, powerful experiences contradict old expectations. Thus, memory is a constructive process, piecing together bits of the past to predict the future. We are still learning how and where this can apply clinically but any good effective psychotherapy will harness this mechanism in the brain.

Our subcortical systems, memories, and prediction models support the brain’s higher functions, like thinking and feeling. The cortex, allows us to learn and adapt. Unlike our primary instincts, learning involves creating predictions about what is adaptive at the moment (instincts are built in, we don’t have to learn them). What we learn as adaptive may therefore differ from instinctive reactions.

Memory Reconsolidation: A Deeper Dive

Karin Nader and Oliver Hardt’s groundbreaking work revolutionized our understanding of memory. Before their research, it was believed that memories formed linearly, transitioning from short-term in the hippocampus to long-term storage elsewhere. They showed that recalling long-term memories makes them unstable and requires reconsolidation to remain long-term. This means memories can change each time they're recalled, making memory a dynamic process.

Their research indicates that after a memory is reactivated, it stays open to new learning for about six hours before reconsolidating. This process doesn’t damage the brain and is specific to individual memories. Memory reconsolidation has since influenced psychotherapy, such as Bruce Ecker’s Coherence Therapy, by showing that old memories can be updated with new emotional experiences, facilitating growth and reducing anxiety.

This concept aligns with Frank Alexander’s idea of the corrective emotional experience, suggesting that updating old memories with new, positive experiences can help resolve long-standing emotional issues. Interestingly, Nader and Hardt were students of neuroscientist Joseph LeDoux, who initially doubted their hypothesis but changed his stance after they proved it correct.

Understanding how our brains learn, adapt, and change through memory reconsolidation not only gives us insight into our own behaviors but also opens up new possibilities for personal growth and therapeutic techniques. Whether we’re dealing with past traumas or looking to improve our adaptive strategies, the dynamic nature of memory offers hope for lasting change.
