- description: |
- Neural computations are often fast and anatomically localized.
- Yet, investigating such computations in humans is challenging because non-invasive methods have either high temporal or spatial resolution, but not both.
- Of particular relevance, fast neural replay is known to occur throughout the brain in a coordinated fashion about which little is known.
- We develop a multivariate analysis method for functional magnetic resonance imaging that makes it possible to study sequentially activated neural patterns separated by less than 100 ms with precise spatial resolution.
- Human participants viewed images individually and sequentially with speeds up to 32 ms between items.
- Probabilistic pattern classifiers were trained on activation patterns in visual and ventrotemporal cortex during individual image trials.
- Applied to sequence trials, probabilistic classifier time courses allow the detection of neural representations and their order.
- Order detection remains possible at speeds up to 32 ms between items.
- The frequency spectrum of the sequentiality metric distinguishes between sub- versus supra-second sequences.
- Importantly, applied to resting-state data our method reveals fast replay of task-related stimuli in visual cortex.
- This indicates that non-hippocampal replay occurs even after tasks without memory requirements and shows that our method can be used to detect such spontaneously occurring replay.
