Data related to: Hippocampal ripples and their coordinated dialogue with the default mode network during recent and remote recollection, Norman et al. (2021)

This dataset contains intra-cranial EEG recordings and analysis code related to the paper: "Hippocampal ripples and their coordinated dialogue with the default mode network during recent and remote recollection" by Norman et al. (https://doi.org/10.1016/j.neuron.2021.06.020)
The study investigates the role of hippocampal ripples in the human brain during retrieval of recent and remote autobiographical memories and semantic facts. The intracranial recordings underwent standard preprocessing as described in the paper and were stored in EEGLAB datasets. The analysis code that accompanies the dataset implements the main analyses described in the paper.

The dataset includes the following zip files:

• iEEG data and main analysis code:
  • “Norman_et_al_2021_iEEG_data_and_code_1.zip" 
  • “Norman_et_al_2021_iEEG_data_and_code_2.zip" 
• Patients' anatomical data:
  • “Norman_et_al_2021_Freesurfer.zip”
• Additional toolboxes (developed by others):
  • “MATLAB_toolboxes.zip”

The code is written primarily in Matlab (version R2018b) and runs on a desktop computer with a 3.4Ghz Intel Core i7-6700 CPU with 64GB RAM. Matlab's Signal Processing Toolbox is required, as well as EEGLAB, Unfold toolbox, and several other open-source toolboxes.
