Penn Electrophysiology of Encoding and Retrieval Study (PEERS)

BEH EEG Zarr

The Penn Electrophysiology of Encoding and Retrieval Study (PEERS) characterizes behavioral and electrophysiological correlates of memory encoding and retrieval in highly practiced individuals. Across five PEERS experiments, more than 300 subjects contributed over 7,000 ninety-minute memory testing sessions with EEG. This dataset includes three free recall experiments: ltpFR (PEERS1-3), ltpFR2 (PEERS4), and VFFR (PEERS5).

Langer et al. 2017 — Multimodal Resource for Studying Information Processing in the Developing Brain (MIPDB)

EEG Zarr

The Multimodal Resource for Studying Information Processing in the Developing Brain (MIPDB) provides high-density 128-channel EEG and eye-tracking recordings from a developmental cohort spanning childhood to adulthood. Participants completed a battery of cognitive and perceptual paradigms, including resting state, surround suppression, naturalistic viewing, contrast change detection, sequence learning, and symbol search. This BIDS conversion contains EEG data from 111 participants, with source eye-tracking and behavioural data preserved in sourcedata.

AJILE12: long-term naturalistic ECoG with wrist-movement events and behaviour labels (DANDI 000055)

iEEG

AJILE12 is a long-term naturalistic intracranial dataset of electrocorticography (ECoG) recorded opportunistically from 12 epilepsy patients during clinical monitoring at Harborview Medical Center. Recordings cover 55 full monitoring days (days 3-7 after implantation) with simultaneous video, from which upper-body pose, validated wrist-movement initiation events and coarse behavioural state labels were derived. This iEEG-BIDS representation converts the original NWB release from DANDI without altering signal values.

EEG During Mental Arithmetic Tasks

EEG Zarr

Scalp EEG recordings from 36 healthy university students during eyes-closed rest and a serial-subtraction mental arithmetic task. The dataset supports study of EEG correlates of cognitive workload and mathematical cognition, with applications in mental workload assessment and brain-computer interfaces. Participants were split post hoc into good and bad counters based on the number of completed subtractions. This BIDS version was converted from the PhysioNet release.
