Infant Right Hemisphere Brain Activity During Rapid Face Image Categorization

Dryad hosts electrophysiological brain recordings from 4–6 month old infants viewing natural object images at 6 images per second. The dataset captures a face-selective neural response at 1.2 Hz over the right hemisphere, absent for phase-scrambled control images. These findings by Adélaïde de Heering, published in 2020, indicate early development of face perception capabilities.

Use Cases

• Analyze the 1.2 Hz frequency-tagged neural response to identify face-selective processing in infant EEG data.
• Compare brain activity patterns between natural face images and phase-scrambled control images to isolate high-level visual categorization.
• Investigate right hemisphere lateralization of the face-selective response across variable stimuli differing in size, viewpoint, and illumination.
• Use the rapid 6 Hz presentation paradigm to study the temporal dynamics of infant visual perception and figure-ground segregation.

Strengths

• Data originates from a controlled experiment using a highly sensitive and objective frequency-tagging EEG approach.
• Stimuli included widely variable natural face images, testing generalization across changes in expression, age, and gender.
• Findings are published and the dataset is openly available under a CC0 1.0 license.

Limitations

• The sample population is limited to infants aged 4–6 months, restricting generalizability to other age groups.
• Specific technical details like the number of infant participants, recording channels, or trial counts are not provided in the input.
• The dataset's structure, file formats, and size are unknown, which may complicate initial data access and processing.
