Summary
Neural network models predict sustained attention across visual and auditory tasks. Functional brain connectivity patterns generalize, suggesting shared mechanisms underlie attention regardless of sensory input.
Area of Science:
- Cognitive Neuroscience
- Neuroimaging
- Psychology
Background:
- Sustained attention is crucial for daily functioning and can involve various sensory inputs like vision and audition.
- Identifying generalizable neural predictors of behavior across datasets is a key goal in cognitive neuroscience.
- Previous research demonstrated that functional connectivity patterns can predict individual differences in sustained attention.
Purpose of the Study:
- To investigate whether connectome-based models predicting visual sustained attention performance generalize to auditory attention tasks.
- To determine if functional brain networks for sustained attention are modality-specific or modality-general.
- To assess the generalizability of whole-brain functional network models for sustained attention across different perceptual modalities.
Main Methods:
- Utilized functional magnetic resonance imaging (fMRI) to measure brain activity and functional connectivity.
- Trained predictive models on fMRI data to link functional connectivity patterns with sustained attention performance.
- Tested model generalizability on independent datasets and across visual and auditory attention tasks.
Main Results:
- A network model trained on visual attention generalized to predict auditory attention performance across three independent datasets.
- Functional networks demonstrated largely modality-general predictive capabilities for sustained attention.
- Both unique and shared features within functional networks predicted sustained attention performance irrespective of task modality.
Conclusions:
- Visual and auditory sustained attention appear to rely on shared neural mechanisms within the brain's functional networks.
- Whole-brain functional network models exhibit robust generalizability for predicting sustained attention.
- Findings support the modality-general nature of neural underpinnings for sustained attention.
