Your brain is not fixed. It is constantly rewiring, adapting, and growing new connections throughout your entire life.
Neuroplasticity
Your brain can rewire itself, at any age
Neuroplasticity is your brain's ability to reorganize, adapt, and form new neural connections in response to learning, experiences, and even injuries, throughout your entire life. Research suggests that learning and therapy are linked to measurable changes in the brain. However, the brain cannot completely regenerate itself after severe damage. What it can do is remarkable: form new brain cells in some regions (how much this happens in adults is still debated), rewire existing connections, and strengthen or weaken synaptic pathways based on what you practice and experience.
When it can help
- Understanding that change is biologically possible at any age
- Building hope that therapy can create lasting brain changes
- Motivating consistent practice of new skills and patterns
- Understanding recovery after brain injury or stroke
What a session feels like
Learning and change in therapy are thought to rely on neuroplasticity. When you practice new ways of thinking, feeling, and behaving, in session and through homework, you may be strengthening new neural pathways. The more you practice, the stronger and more automatic these new patterns become.
How healing happens
New experiences and practice → new neural connections form → repeated practice strengthens them → lasting change becomes the new default
Who developed it
The concept has roots in Santiago Ramón y Cajal's early work; modern research advanced by Michael Merzenich, Eric Kandel (Nobel Prize, 2000), and others. Hebbian theory (Donald Hebb, 1949) provides the foundational principle
Good to know
Neuroscientist Carla Shatz coined the famous summary of Hebb's principle: 'Cells that fire together, wire together.' Every time you practice a thought pattern or behavior, you physically strengthen that neural circuit, for better or worse.
Mirror Neurons
Built to understand each other
Your brain contains a 'mirror neuron system,' networks that activate both when you perform an action and when you observe someone else performing that same action. This is thought to be a biological foundation for empathy, social learning, and understanding others' intentions. Individual mirror neurons have been directly observed in animals; in humans, brain imaging reveals broader mirror neuron systems rather than isolated cells.
When it can help
- Understanding the neuroscience of empathy
- Making sense of why emotions are 'contagious'
- Understanding how we learn by watching others
- Appreciating the biological basis of human connection
What a session feels like
Feeling safe around a calm person may help your body settle, and some researchers wonder whether mirror neuron systems play a role (this is debated). When your therapist is calm and regulated, your nervous system can 'mirror' that state through co-regulation. Group therapy can also be powerful, because you can learn from and feel supported by seeing others work through similar struggles.
How healing happens
Observing regulation in others → mirror systems activate → your own nervous system learns new patterns → expanded capacity for connection
Who developed it
Discovered by Giacomo Rizzolatti and colleagues at the University of Parma, Italy (1990s)
Good to know
The existence and exact function of mirror neurons in humans is still being researched and debated. What is well-established is that humans have brain systems that respond to observing others' actions and emotions, a biological foundation for our social nature.
