Hypothesis
How does neurophysiological activity of cortical structures relate to subjective time estimations?
Conclusion
Different brain regions are involved in time estimation depending on whether the eyes are open or closed.
Supporting Evidence
- Beta-band activity in the left precuneus correlated with longer subjective minutes when eyes were closed.
- Different brain regions showed opposite correlations for time estimation depending on whether the eyes were open or closed.
- Participants produced similar subjective minute durations in both conditions, around 58 seconds.
Takeaway
This study looked at how our brain tells time when we can see or when we can't, finding that different parts of the brain help us estimate time in each situation.
Methodology
Participants estimated 1-minute intervals with eyes open and closed while their brain activity was recorded using EEG.
Limitations
EEG has low spatial resolution and the study's correlational design limits causal conclusions.
