This Phase I clinical trial studied the effects of non-invasive neuromodulation-induced prehabilitation (NIP) on the language production network in 26 patients with operable brain tumors affecting language regions. The language-targeted NIP group showed reduced overlap between stimulation targets and language activation maps, indicating selective modulation of the language network without compromising cognitive function.
Key findings
- The language-targeted NIP group showed reduced overlap between stimulation targets and language activation maps.
- No significant modulation effects were detected in the motor network in either group.
- Language and cognitive performance were preserved during the modulation of the language production network.
Why it matters
Understanding how prehabilitation can selectively reorganize critical language networks without impairing function is essential for optimizing surgical outcomes in patients with brain tumors. This approach may allow for more extensive resections while maintaining essential cognitive abilities.
