What Is Neuroplasticity?

The science of how the brain changes itself

Once you appreciate plasticity, you never train casually again.

Definition

Neuroplasticity refers to synaptic and structural changes that occur when neurons fire together repeatedly. It is the biological foundation of learning.

Plasticity can be functional (changing synapse strength) or structural (growing new branches, adding myelin).

Triggers & Inhibitors

Focused attention, novelty, urgency, and reward drive plastic changes. Chronic stress, monotony, and sleep deprivation blunt them.

Neurochemicals like acetylcholine and dopamine signal “this matters”—without them the brain ignores practice.

Applying Plasticity to Training

Design sessions that begin with priming (movement, breath) to raise attention, followed by intense but brief practice, then immediate rest or contrasting activity.

Log progress and celebrate micro-wins to keep dopamine involved, ensuring the brain tags the session as valuable.

Action Steps

Prime before practice

Use cardio or breathwork to raise acetylcholine before drilling.

Train in waves

Cycle 15 minutes of focused practice with 5 minutes of rest.

Sleep like it matters

Protect deep sleep so plastic changes consolidate.

Frequently Asked Questions

Does plasticity slow with age?

It declines slightly but never disappears. Adults simply need deliberate practice and recovery.

Can plasticity be harmful?

Yes—bad habits also wire in. Be intentional about what you repeat.
