This dataset contains intracranial EEG (stereo-EEG) recordings acquired during 41 high-frequency electrical cortical stimulations that evoked negative motor responses. Data come from 23 patients undergoing presurgical evaluation for drug-resistant epilepsy. Each recording spans about 24 seconds around a stimulation and includes pre- and post-stimulation 5-second epochs, which were used for connectivity analysis. Stimulation contact pairs, current intensities and evoked effects are annotated in the events files.
This derivative dataset repackages figure-level arrays from Tong et al. (2021), which examined hippocampal-adjacent anterior temporal lobe ripples in patients with drug-resistant epilepsy performing a paired-associates verbal memory task. It contains ripple-band signals, time-frequency power, ripple rasters, micro-LFP and spike data from subdural/depth iEEG contacts and 96-channel Utah microelectrode arrays, covering 7 participants and the panels of Figures 1-4. Raw continuous recordings are not included. Session date strings were removed for privacy.

Epoched intracranial EEG from 11 epilepsy patients (22 recordings, about 9 hours of epochs at 200 Hz) recorded during an object/scene localiser task and an associative recall task. The data are the extra-hippocampal channels released by Treder et al. (2021) on OSF and repackaged into BIDS iEEG format. The original study examined the role of the hippocampus as a switchboard between perception and memory.
EEG dataset from an instruction-following study in which participants received novel verbal instructions combining integration or selection of animate and inanimate images, a relevant feature (color or shape), and a response key. Each participant completed a main instruction-following task and a 1-back localizer task in a single session. The dataset supports investigation of neural representations of novel instructions.

This dataset contains behavioral events and intracranial EEG recordings from a delayed free recall task in which participants studied visually presented word lists, solved arithmetic distractor problems, and then freely recalled the words. Data were collected at multiple clinical sites in collaboration with the Computational Memory Lab at the University of Pennsylvania. Monopolar and bipolar recordings are provided with subject-specific electrode montages, MNI/Talairach coordinates, and brain region annotations.
