Infant Macaque Visual Cortex BOLD fMRI Data Across Development

Functional MRI data from seven infant macaque monkeys scanned repeatedly over an age range of 102 to 1431 days. The dataset includes BOLD responses to large rotating checkerboard stimuli and Glass pattern stimuli, analyzed with GLM and multivoxel pattern analysis (MVPA) methods. It focuses on contrasts such as Glass pattern present/absent and static/dynamic presentation across visual areas V1, V4, and MT-V5.

Use Cases

• Analyze the developmental trajectory of BOLD activation in V1, V4, and MT-V5 in response to Glass pattern stimuli across the 102-1431 day age range.
• Compare GLM and MVPA analysis results for contrasts like static/dynamic Glass pattern presentation to assess method sensitivity.
• Investigate the hierarchical development of dorsal and ventral visual streams using BOLD responses to structured/random Glass pattern form.
• Model the relationship between age and the emergence of robust differential BOLD activity for the Glass pattern present/absent contrast.

Strengths

• Longitudinal data from seven subjects scanned repeatedly over a wide developmental window of 102 to 1431 days.
• Includes BOLD responses to multiple stimulus types (checkerboard, Glass patterns) analyzed with two distinct methods (GLM, MVPA).
• Focuses on three specific analytical contrasts (Glass pattern present/absent, static/dynamic, structured/random) across key visual areas.

Limitations

• Small sample size of seven infant macaques limits statistical power and generalizability.
• Data collected under anesthesia, which may not reflect fully naturalistic visual processing or behavioral states.
• No raw columnar data or sample data is available for independent verification or alternative analysis.
