The implant hemisphere (side), age, sex, number of reading/repetition trials, and grid specifications for all eight subjects in the study are listed here. Associated neuroimaging and electrode localization can be found in Figure 2. Channels are delineated by region of interest, and further by the diameter of the electrode's exposed area, then by the inter-electrode spacing. SD: Standard macro-array (2 mm diameter, 1 cm pitch). HD-5: High density array (2 mm diameter, 5 mm pitch). HD-3: High density array (1 mm diameter, 3 mm pitch). μ: Micro-ECoG array (75 μm diameter, 1 mm pitch).
120 trials were recorded, but the synchronized microphone recording failed for the second set of 60 trials. Neural keyword spotting can be applied to this second block, but ground truth timing metrics are unavailable.
Recording session ended early.
