Neuroplasticity
The brain's ability to reorganize itself by forming new neural connections.
Does visualisation physically change the brain?
The brain does reorganise with repeated experience, and imagery is a form of repeated experience. What the evidence does not support is the stronger claim that picturing a goal rewires you into achieving it. Structural change follows sustained practice, not exposure alone.

Frequently asked
How long does change take?
Meaningful structural change is measured in weeks to months of consistent practice, not days. Any source promising a rewired brain in a week is overstating the literature.
Is 'neurons that fire together, wire together' accurate?
It is a useful summary of Hebbian learning and it is also a simplification. It describes how repeated co-activation strengthens connections; it does not mean that imagining an outcome produces it.
