LFP frequency and temporal resolution
1,820 area×frequency cells; 114 are temporally resolved. Whether independent estimators agree on when the change happened is itself the informative quantity here.
Unresolved does not mean unmodulated. Low-frequency LFP power can change strongly while its onset remains poorly localized in time. Response magnitude and temporal resolution are separate measurements, and this page reports only the second.
B1 · P(resolved | frequency)
B2 · LOW vs HIGH, paired within session
One line per session. The pairing is what makes this inferential: each session contributes a single difference Ds, so between-session and between-subject variation cannot inflate n.
median D = +7.27 percentage points · exact exhaustive sign-flip permutation p = 8.39e-05 (262,144 assignments enumerated over 18 non-zero sessions of 21) · Holm p = 1.7e-04 replicated across sessions
B4 · Censoring, and why there is no beta onset distribution
Beta latencies are strongly left-censored. Of 36 resolved beta cells, 17 sit exactly on the lower search bound and 25 (69%) fall at or below 20 ms. A naive beta onset distribution would report a bound, not a measurement, so none is shown here and boundary-pinned values are never rendered as ordinary latencies.
| band | n_resolved | n_at_lower_bound | n_le_20ms | frac_le_20ms | median_T_om_unpinned_ms |
|---|---|---|---|---|---|
| theta | 3 | 0 | 0 | 0 | 309 |
| alpha | 5 | 1 | 1 | 0.2 | 149.5 |
| beta | 36 | 17 | 25 | 0.69 | 193 |
| low_gamma | 36 | 1 | 8 | 0.22 | 59.5 |
| high_gamma | 24 | 0 | 2 | 0.08 | 139.5 |
| out_of_band | 10 | 0 | 1 | 0.1 | 152 |
Theta and alpha resolve too few cells (3 and 5 respectively) to support corpus latency claims. Low and high gamma are the main descriptive LFP timing regimes.
