Data and code for: Large-Scale Maps of Altered Cortical Dynamics in Early-Stage Psychosis Are Related to GABAergic and Glutamatergic Neurotransmission

DOI

This repository contains: 

  1. Raw MEG resting state data of a pharmacological experiment, which include the administration of lorazepam, memantine or placebo. Info_filewise.xlsx contains a list with file name, session number and drug. See README file for more information. 

  2. Power spectral density (PSD) and the fitted FOOOF models of the above-mentioned raw data, for each parcel in the anatomical atlas by Glasser et al., 2016. 

  3. Two sets of six dynamics parameters, one for the pharmacological experiment and one of a clinical dataset. The latter contains 191 participants: 32 patients with first episode psychosis, 114 participants with clinical high risk for psychosis, and 45 healthy controls. 

  4. Code and supporting files for generating the results in Arazi et al., 2025. See https://github.com/DonnerLab/2025_Arazi_Large-scale-dynamical-signatures-of-psychosis for more info.
