Summary
Brain activity differs between surgeons using laparoscopic and robotic surgery. Laparoscopic surgery increases intra-hemispheric brain coherence, while robotic surgery enhances inter-hemispheric coherence, revealing distinct neural coordination patterns.
Area of Science:
- Neuroscience
- Surgical Technology
- Brain-Computer Interfaces
Background:
- Voluntary movement control involves primary and non-primary motor areas.
- Functional coupling dynamics among motor areas remain unclear.
- No prior research compared brain dynamics in laparoscopic versus robotic surgery.
Purpose of the Study:
- To investigate and compare functional brain dynamics in surgeons using laparoscopic versus robotic surgical approaches.
- To assess differences in intra- and inter-hemispheric electroencephalogram (EEG) coherence during surgical tasks.
Main Methods:
- 16 trained surgeons performed a standardized motor task using either a laparoscopic or robotic approach.
- 32-channel EEG recorded neural activity.
- Fast Fourier Transform algorithm in MATLAB 5.3 analyzed EEG coherence spectra.
Main Results:
- Laparoscopic surgery showed increased intra-hemispheric coherence (theta and lower alpha bands) between motor areas (M1, S1, SMA, pre-SMA).
- Robotic surgery demonstrated increased inter-hemispheric coherence (upper alpha and beta bands) between homologous and some non-homologous motor areas.
- Both approaches showed statistically significant differences (p < 0.001).
Conclusions:
- Surgical approach (laparoscopic vs. robotic) differentially activates and coordinates motor and non-motor cortical areas.
- This study provides the first semi-quantitative assessment of brain-device interaction differences in surgical contexts.
- Findings highlight distinct neural engagement patterns based on surgical technology used.
