Mental rehearsal activates the <strong>motor cortex</strong>, the <strong>premotor cortex</strong>, and the <em>supplementary motor area — the brain&rsquo;s internal movement planning hub</em> — in patterns measurably similar to actual physical execution. But the claim that &ldquo;your brain can&rsquo;t tell the difference&rdquo; between imagined and real movement is neurologically imprecise. Ultra-high-field 7T fMRI reveals a critical distinction: imagery recruits only the superficial layers of primary motor cortex, while actual movement engages both superficial and deep cortical layers. In my practice, I&rsquo;ve found this nuance — the partial overlap rather than total equivalence — is exactly what makes structured mental rehearsal so effective as a neural training tool.</p>
