Brain Correlates of Speech Perception in Schizophrenia

This dataset contains materials from the study "Brain correlates of speech perception in schizophrenia patients with and without auditory hallucinations" by Soler-Vidal et al. (2022), aimed at studying the neural activation patterns associated with speech perception in healthy participants and individuals with schizophrenia, with and without auditory hallucinations.

🧠 Dataset Description

This repository provides a 2D slice-based version of the original t1w dataset, designed for efficient deep learning and representation learning workflows.

Each entry corresponds to a single 2D t1w slice extracted from a volume and includes both imaging metadata and participant-level clinical information.

📦 Dataset Structure

Each dataset entry contains:

volume_id → Unique identifier for the t1w volume/participant
slice_id → Index of the slice within the volume
image → 2D fMRI slice
age → Participant age
sex → Participant sex
iq → Intelligence quotient score
diagnosis → Clinical diagnosis (healthy or schizophrenia)
with_auditory_hallucinations → Boolean indicating whether the participant experiences auditory hallucinations

Use

from datasets import load_dataset
import matplotlib.pyplot as plt

dataset = load_dataset("chehablaborg/schizophrenia_speech_perception", split="train")

sample_id = 314

image = dataset[sample_id]["image"]
diagnosis = dataset[sample_id]["diagnosis"]

plt.imshow(image, cmap="gray")
plt.title(diagnosis)
plt.show()
