Clinical data and average changes in HbO2 concentration during the clinical recordings
| Patient | Age (sex) | Handiness (profession) | Recording duration (# blocs) | Technical issues | Diagnosis | Additional neuroimaging modalities | Δ [HbO2] (µmol/l) |
|---|---|---|---|---|---|---|---|
| C1 | 63 (M) | R (retired) | 2 × 1 h | None | LS‐TIA |
MRA: L occlusion of M1, R severe supraclinoid ICA stenosis ASL: decrease rCBF within the L MCA territory |
LH* = −1.50 RH* = −1.50 |
| C2 | 23 (F) | R (educator) | 10 h | None | Bi‐temporal lobe epilepsy | iSPECT: increase CBF over the middle and posterior portions of the right TL |
LT = 29.75 RT = 71.09 |
| C3 | 30 (F) | R (student) | 24 h | Helmet not ICU‐friendly | Refractory SE |
iiSPECT: R posterior temporal seizure focus MEG: temporal spikes from the posterior portion of the insula and R temporal opercula |
LF** = 0.49 RF** = 1.63 RT** = 0.51 |
| C4 | 51 (F) | Right (retired) | 8 h (N = 7) | None | Stroke, refractory epilepsy | fMRI: R language dominance |
BL = 0.40 BR = 0.85 (LIN = −0.36) |
M: male; F: female; R: right; L: left; HbO2: oxyhemoglobin; LI: laterality index; BL: Broca left; BR: Broca right; LH: left hemisphere; RH: right hemisphere; LT: left temporal RT: right temporal; LF: left frontal; RF: right frontal; TL: temporal lobe; ICU: intensive care unit; MRA: magnetic resonance angiography; ASL: arterial spin labeling; rCBF: regional cerebral blood flow; iSPECT: ictal single position emission computed tomography; iiSPECT: interictal single positron emission computed tomography; MEG: magnetoencephalography; fMRI: functional magnetic resonance imaging; *: one session of recording, **: one burst of seizure.
